The SAA7114H is a video capture device for applications at the image port of VGA controllers. The SAA7114H is a combination of a two-channel analog preprocessing circuit including source selection, anti-aliasing filter and ADC, an automatic clamp and gain control, a Clock Generation Circuit (CGC), a digital multi-standard decoder containing two-dimensional chrominance/luminance separation by an adaptive comb filter and a high performance scaler, including variable horizontal and vertical up and down scaling and a brightness, contrast and saturation control circuit. It is a highly integrated circuit for desktop video applications. The decoder is based on the principle of line-locked clock decoding and is able to decode the colour of PAL, SECAM and NTSC signals into ITU 601 compatible colour component values. The SAA7114H accepts as analog inputs CVBS or S-video (Y/C) from TV or VCR sources, including weak and distorted signals. An expansion port (X-port) for digital video (bi-directional half duplex, D1 compatible) is also supported to connect to MPEG or video phone codec. At the so called image port (I-port) the SAA7114H supports 8 or 16-bit wide output data with auxiliary reference data for interfacing to VGA controllers. The target application for SAA7114H is to capture and scale video images, to be provided as digital video stream through the image port of a VGA controller, for display via VGA's frame buffer, or for capture to system memory. In parallel SAA7114H incorporates also provisions for capturing the serially coded data in the vertical blanking interval (VBI-data). Two principal functions are available: 1. To capture raw video samples, after interpolation to the required output data rate, via the scaler 2. A versatile data slicer (data recovery) unit.
* Power-on control * 5 V tolerant digital inputs and I/O ports * Software controlled power saving standby modes supported * Programming via serial I2C-bus, full read-back ability by an external controller, bit rate up to 400 kbits/s * Boundary scan test circuit complies with the "IEEE Std. 1149.b1 - 1994". 2 APPLICATIONS
* Desktop video * Multimedia * Digital television * Image processing * Video phone applications.
SAA7114H incorporates also a field locked audio clock generation. This function ensures that there is always the same number of audio samples associated with a field, or a set of fields. This prevents the loss of synchronization between video and audio, during capture or playback. The circuit is I2C-bus controlled (full write/read capability for all programming registers, bit rate up to 400 kbits/s).

1. In accordance with the "IEEE1149.1" standard the pads TDI, TMS, TCK and TRST are input pads with an internal pull-up transistor and TDO is a 3-state output pad. 2. Pin strapping is done by connecting the pin to supply via a 3.3 k resistor. During the power-up reset sequence the corresponding pins are switched to input mode to read the strapping level. For the default setting no strapping resistor is necessary (internal pull-down). 3. Pin RTCO: operates as I2C-bus slave address pin; RTCO = 0 slave address 42H/43H (default); RTCO = 1 slave address 40H/41H. 4. Pin ALRCLK: 0 = 24.576 MHz crystal (default); 1 = 32.110 MHz crystal. 5. For board design without boundary scan implementation connect the TRST pin to ground. 6. This pin provides easy initialization of the Boundary Scan Test (BST) circuit. TRST can be used to force the Test Access Port (TAP) controller to the TEST_LOGIC_RESET state (normal operation) at once.

8.1.2.1 Clamping
SAA7114H
The clamp control circuit controls the correct clamping of the analog input signals. The coupling capacitor is also used to store and filter the clamping voltage. An internal digital clamp comparator generates the information with respect to clamp-up or clamp-down. The clamping levels for the two ADC channels are fixed for luminance (60) and chrominance (128). Clamping time in normal use is set with the HCL pulse at the back porch of the video signal.
The AGC (automatic gain control for luminance) is used to amplify a CVBS or Y signal to the required signal amplitude, matched to the ADCs input voltage range. The AGC active time is the sync bottom of the video signal. Signal (white) peak control limits the gain at signal overshoots. The flow charts (see Figs 7 and 8) show more details of the AGC. The influence of supply voltage variation within the specified range is automatically eliminated by clamp and automatic gain control.
8.1.2.2
Gain control
The gain control circuit receives (via the I2C-bus) the static gain levels for the two analog amplifiers or controls one of these amplifiers automatically via a built-in Automatic Gain Control (AGC) as part of the Analog Input Control (AICO).

8.1.3.1 Chrominance path
SAA7114H
The 9-bit CVBS or chrominance input signal is fed to the input of a quadrature demodulator, where it is multiplied by two time-multiplexed subcarrier signals from the subcarrier generation block 1 (0 and 90 phase relationship to the demodulator axis). The frequency is dependent on the chosen colour standard. The time-multiplexed output signals of the multipliers are low-pass filtered (low-pass 1). Eight characteristics are programmable via LCWB3 to LCWB0 to achieve the desired bandwidth for the colour difference signals (PAL, NTSC) or the 0 and 90 FM signals (SECAM). The chrominance low-pass 1 characteristic also influences the grade of cross-luminance reduction during horizontal colour transients (large chrominance bandwidth means strong suppression of cross-luminance). If the Y-comb filter is disabled by YCOMB = 0 the filter influences directly the width of the chrominance notch within the luminance path (large chrominance bandwidth means wide chrominance notch resulting to lower luminance bandwidth). The low-pass filtered signals are fed to the adaptive comb filter block. The chrominance components are separated from the luminance via a two line vertical stage (four lines for PAL standards) and a decision logic between the filtered and the non-filtered output signals. This block is bypassed for SECAM signals. The comb filter logic can be enabled independently for the succeeding luminance and chrominance processing by YCOMB (subaddress 09H, bit 6) and/or CCOMB (subaddress 0EH, bit 0). It is always bypassed during VBI or raw data lines programmable by the LCRn registers (subaddresses 41H to 57H), see Section 8.2. The separated UV-components are further processed by a second filter stage (low-pass 2) to modify the chrominance bandwidth without influence to the luminance path. It's characteristic is controlled by CHBW (subaddress 10H, bit 3). For the complete transfer characteristic of low-passes 1 and 2 see Figs 10 and 11. The SECAM processing (bypassed for QUAM standards) contains the following blocks: * Baseband `bell' filters to reconstruct the amplitude and phase equalized 0 and 90 FM signals * Phase demodulator and differentiator (FM-demodulation) * De-emphasis filter to compensate the pre-emphasized input signal, including frequency offset compensation (DB or DR white carrier values are subtracted from the signal, controlled by the SECAM switch signal). 2000 Mar 15 19
The succeeding chrominance gain control block amplifies or attenuates the UV-signal according to the required ITU 601/656 levels. It is controlled by the output signal from the amplitude detection circuit within the burst processing block. The burst processing block provides the feedback loop of the chrominance PLL and contains: * Burst gate accumulator * Colour identification and killer * Comparison nominal/actual burst amplitude (PAL/NTSC standards only) * Loop filter chrominance gain control (PAL/NTSC standards only) * Loop filter chrominance PLL (only active for PAL/NTSC standards) * PAL/SECAM sequence detection, H/2-switch generation. The increment generation circuit produces the Discrete Time Oscillator (DTO) increment for both subcarrier generation blocks. It contains a division by the increment of the line-locked clock generator to create a stable phase-locked sine signal under all conditions (e.g. for non-standard signals). The PAL delay line block eliminates crosstalk between the chrominance channels in accordance with the PAL standard requirements. For NTSC colour standards the delay line can be used as an additional vertical filter. If desired, it can be switched off by DCVF = 1. It is always disabled during VBI or raw data lines programmable by the LCRn registers (subaddresses 41H to 47H), see Section 8.2. The embedded line delay is also used for SECAM recombination (cross-over switches).

8.1.3.2 Luminance path
SAA7114H
The rejection of the chrominance components within the 9-bit CVBS or Y input signal is done by subtracting the re-modulated chrominance signal from the CVBS input. The comb filtered UV-components are interpolated (upsampled) by the low-pass 3 block. It's characteristic is controlled by LUBW (subaddress 09H, bit 4) to modify the width of the chrominance `notch' without influence to the chrominance path. The programmable frequency characteristics available in conjunction with the LCBW2 to LCBW0 settings can be seen in Figs 12 to 15. Note that these frequency curves are only valid for Y-comb disabled filter mode (YCOMB = 0). in comb filter mode the frequency response is flat. The centre frequency of the notch is automatically adapted to the chosen colour standard. The interpolated UV-samples are multiplied by two time-multiplexed subcarrier signals from the subcarrier generation block 2. This second DTO is locked to the first subcarrier generator by an increment delay circuit matched to the processing delay, which is different for PAL and NTSC standards according to the chosen comb filter algorithm. The two modulated signals are finally added to build the re-modulated chrominance signal.
The frequency characteristic of the separated luminance signal can be further modified by the succeeding luminance filter block. It can be configured as peaking (resolution enhancement) or low-pass block by LUFI3 to LUFI0 (subaddress 09H, bits 3 to 0). The 16 resulting frequency characteristics can be seen in Fig.16. The LUFI3 to LUFI0 settings can be used as a user programmable sharpness control. The luminance filter block also contains the adjustable Y-delay part; programmable by YDEL2 to YDEL0 (subaddress 11H, bits 2 to 0).

8.1.4 SYNCHRONIZATION
SAA7114H
The prefiltered luminance signal is fed to the synchronization stage. Its bandwidth is further reduced to 1 MHz in a low-pass filter. The sync pulses are sliced and fed to the phase detectors where they are compared with the sub-divided clock frequency. The resulting output signal is applied to the loop filter to accumulate all phase deviations. Internal signals (e.g. HCL and HSY) are generated in accordance with analog front-end requirements. The loop filter signal drives an oscillator to generate the line frequency control signal LFCO, see Fig.19. The detection of `pseudo syncs' as part of the macrovision copy protection standard is also done within the synchronization circuit. The result is reported as flag COPRO within the decoder status byte at subaddress 1FH. 8.1.5 CLOCK GENERATION CIRCUIT
The internal signal LFCO is a digital-to-analog converted signal provided by the horizontal PLL. It is the multiple of the line frequency: 6.75 MHz = 429 x fH (50 Hz), or 6.75 MHz = 432 x fH (60 Hz). Internally the LFCO signal is multiplied by a factor of 2 and 4 in the PLL circuit (including phase detector, loop filtering, VCO and frequency divider) to obtain the output clock signals. The rectangular output clocks have a 50% duty factor. Table 2 Decoder clock frequencies CLOCK XTALO LLC LLC2 LLC4 (internal) LLC8 (virtual) FREQUENCY (MHz) 24.576 or 32.110 27 13.5 6.75 3.375

POWER-ON RESET AND CHIP ENABLE (CE) INPUT
A missing clock, insufficient digital or analog VDDA0 supply voltages (below 2.7 V) will start the reset sequence; all outputs are forced to 3-state (see Fig.20). The indicator output RES is LOW for about 128 LLC after the internal reset and can be applied to reset other circuits of the digital TV system.
It is possible to force a reset by pulling the Chip Enable (CE) to ground. After the rising edge of CE and sufficient power supply voltage, the outputs LLC, LLC2 and SDA return from 3-state to active, while the other signals have to be activated via programming.

8.2 Decoder output formatter
SAA7114H
The output interface block of the decoder part contains the ITU 656 formatter for the expansion port data output XPD7 to XPD0 (for a detailed description see Section 9.4.1) and the control circuit for the signals needed for the internal paths to the scaler and data slicer part. It also controls the selection of the reference signals for the RT port (RTCO, RTS0 and RTS1) and the expansion port (XRH, XRV and XDQ). The generation of the decoder data type control signals SET_RAW and SET VBI is also done within this block. These signals are decoded from the requested data type for the scaler input and/or the data slicer, selectable by the control registers LCR2 to LCR24 (see also Chapter 15 "I2C-bus description", subaddresses 41H to 57H). Table 3 Data formats at decoder output DATA TYPE teletext EuroWST, CCST European closed caption
For each LCR value from 2 to 23 the data type can be programmed individually. LCR2 to LCR23 refer to line numbers. The selection in LCR24 values is valid for the rest of the corresponding field. The upper nibble contains the value for field 1 (odd), the lower nibble for field 2 (even). The relationship between LCR values and line numbers can be adjusted via VOFF8 to VOFF0, located in subaddresses 5BH (bit 4) and 5AH (bits 7 to 0) and FOFF subaddress 5BH (bit D7). The recommended values are VOFF[8:0] = 03H for 50 Hz sources (with FOFF = 0) and VOFF[8:0] = 06H for 60 Hz sources (with FOFF = 1), to accommodate line number conventions as used for PAL, SECAM and NTSC standards; see Tables 4 to 7.

8.3 Scaler
SAA7114H
The High Performance video Scaler (HPS) is based on the system as implemented in SAA7140, but enhanced in some aspects. Vertical upsampling is supported and the processing pipeline buffer capacity is enhanced, to allow more flexible video stream timing at the image port, discontinuous transfers, and handshake. The internal data flow from block to block is discontinuous dynamically, due to the scaling process itself. The flow is controlled by internal data valid and data request flags (internal handshake signalling) between the sub-blocks. Therefore the entire scaler acts as a pipeline buffer. Depending on the actually programmed scaling parameters the effective buffer can exceed to an entire line. The access/bandwidth requirements to the VGA frame buffer are reduced significantly. The high performance video scaler in SAA7114H has the following major blocks. * Acquisition control (horizontal and vertical timer) and task handling (the region/field/frame based processing) * Prescaler, for horizontal down-scaling by an integer factor, combined with appropriate band limiting filters, especially anti-aliasing for CIF format * Brightness, saturation, contrast control for scaled output data * Line buffer, with asynchronous read and write, to support vertical up-scaling (e.g. for videophone application, converting 240 into 288 lines, YUV 4 : 2 : 2) * Vertical scaling, with phase accurate Linear Phase Interpolation (LPI) for zoom and down-scale, or phase accurate Accumulation Mode (ACM) for large down-scaling ratios and better alias suppression * Variable Phase Delay (VPD), operates as horizontal phase accurate interpolation for arbitrary non-integer scaling ratios, supporting conversion between square (SQR) and rectangular (CCIR) pixel sampling * Output formatter for scaled YUV 4 : 2 : 2, YUV 4 : 1 : 1 and Y only (format also for raw data) * FIFO, 32-bit wide, with 64 pixel capacity in YUV formats * Output interface, 8 or 16 (only if extended by H-port) data pins wide, synchronous or asynchronous operation, with stream events on discrete pins, or coded in the data stream.
The overall H and V zooming (HV_zoom) is restricted by the input/output data rate relations. With a safety margin of 2% for running in and running out, the maximum HV_zoom is equal to: T_input_field - T_v_blanking 0.98 x ------------------------------------------------------------------------------------------------------------------------------------in_pixel x in_lines x out_cycle_per_pix x T_out_clk For example: 1. Input from decoder: 50 Hz, 720 pixel, 288 lines, 16-bit data at 13.5 MHz data rate, 1 cycle per pixel; output: 8-bit data at 27 MHz, 2 cycles per pixel; the maximum HV_zoom is equal to: 20 ms - 24 x 64 s 0.98 x -------------------------------------------------------- = 1.18 720 x 288 x 2 x 37 ns 2. Input from X-port: 60 Hz, 720 pixel, 240 lines, 8-bit data at 27 MHz data rate (ITU 656), 2 cycles per pixel; output via I + H-port: 16-bit data at 27 MHz clock, 1 cycle per pixel; the maximum HV_zoom is equal to: 16.666 ms - 22 x 64 s 0.98 x ------------------------------------------------------------- = 2.34 720 x 240 x 1 x 37 ns The video scaler receives its input signal from the video decoder or from the expansion port (X-port). It gets 16-bit YUV 4 : 2 : 2 input data at a continuous rate of 13.5 MHz from the decoder. Discontinuous data stream can be accepted from the expansion port (X-port), normally 8-bit wide ITU 656 like YUV data, accompanied by a pixel qualifier on XDQ. The input data stream is sorted into two data paths, one for luminance (or raw samples), and one for time multiplexed chrominance U and V samples. An YUV 4 : 1 : 1 input format is converted to 4 : 2 : 2 for the horizontal prescaling and vertical filter scaling operation. The scaler operation is defined by two programming pages A and B, representing two different tasks, that can be applied field alternating or to define two regions in a field (e.g. with different scaling range, factors, and signal source during odd and even fields). Each programming page contains control: * For signal source selection and formats * For task handling and trigger conditions * For input and output acquisition window definition * For H-prescaler, V-scaler and H-phase scaling.

PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC comb filter, VBI-data slicer and high performance scaler
Raw VBI-data will be handled as specific input format and need an own programming page (= own task). In VBI pass through operation the processing of prescaler and vertical scaling has to be set to no-processing, but the horizontal fine scaling VPD can be activated. Upscaling (oversampling, zooming), free of frequency folding, up to factor 3.5 can be achieved, as required by some software data slicing algorithms. These raw samples are transported through the image port as valid data and can be output as Y only format. The lines are framed by SAV and EAV codes. 8.3.1 ACQUISITION CONTROL AND TASK HANDLING (SUBADDRESSES 80H, 90H, 94H TO 9FH AND C4H TO CFH)
SAA7114H
(XD11 to XD0, YD11 to YD0) closes the window, but the window is cut vertically, if there are less output lines than expected. The trigger events for the pixel and line counts are the horizontal and vertical reference edges as defined in subaddress 92H. The task handling is controlled by subaddress 90H (see Section 8.3.1.2).
8.3.1.1
Input field processing
The acquisition control receives horizontal and vertical synchronization signals from the decoder section or from the X-port. The acquisition window is generated via pixel and line counters at the appropriate places in the data path. From X-port only qualified pixels and lines (= lines with qualified pixel) are counted. The acquisition window parameters are: * Signal source selection regarding input video stream and formats from the decoder, or from X-port (programming bits SCSRC[1:0]91H[5:4] and FSC[2:0]91H[2:0]) Remark: The input of raw VBI-data from internal decoder should be controlled via the decoder output formatter and the LCR registers (see Section 8.2 "Decoder output formatter") * Vertical offset defined in lines of the video source, parameter YO[11:0]99H[3:0]98H[7:0] * Vertical length defined in lines of the video source, parameter YS[11:0]9BH[11:8]9AH[7:0] * Vertical length defined in number of target lines, as result of vertical scaling, parameter YD[11:0]9FH[11:8]9EH[7:0] * Horizontal offset defined in number of pixels of the video source, parameter XO[11:0]95H[3:0]94H[7:0] * Horizontal length defined in number of pixels of the video source, parameter XS[11:0]97H[3:0]96H[7:0] * Horizontal destination size, defined in target pixels after fine scaling, parameter XD[11:0]9DH[3:0]9CH[7:0]. The source start offset (XO11 to XO0, YO11 to YO0) opens the acquisition window, and the target size
The trigger event for the field sequence detection from external signals (X-port) are defined in subaddress 92H. From the X-port the state of the scalers H-reference signal at the time of the V-reference edge is taken as field sequence identifier FID. For example, if the falling edge of the XRV input signal is the reference and the state of XRH input is logic 0 at that time, the detected field ID is logic 0. The bits XFDV[92H[7]] and XFDH[92H[6]] are defining the detection event and state of the flag from the X-port. For the default setting of XFDV and XFDH at `00' the state of the H-input at the falling edge of the V-input is taken. The scaler directly gets a corresponding field ID information from the SAA7114H decoder path. The FID flag is used to determine, whether the first or second field of a frame is going to be processed within the scaler and it is used as trigger condition for the task handling (see bits STRC[1:0]90H[1:0]). According to ITU 656, FID at logic 0 means first field of a frame. To ease the application, the polarities of the detection results on the X-port signals and the internal decoder ID can be changed via XFDH. As the V-sync from the decoder path has a half line timing (due to the interlaced video signal), but the scaler processing only knows about full lines, during 1st fields from the decoder the line count of the scaler possibly shifts by one line, compared to the 2nd field. This can be compensated by switching the V-trigger event, as defined by XDV0, to the opposite V-sync edge or by using the vertical scalers phase offsets. The vertical timing of the decoder can be seen in Figs 21 and 22. As the H and V reference events inside the ITU 656 data stream (from X-port) and the real-time reference signals from the decoder path are processed differently, the trigger events for the input acquisition also have to be programmed differently.

Task handling
Remarks: * To activate a task the start condition must be fulfilled and the acquisition window offsets must be reached. For example, in case of `start immediately', and two regions are defined for one field, the offset of the lower region must be greater than (offset + length) of upper region, if not, the actual counted H and V position at the end of the upper task is beyond the programmed offsets and the processing will `wait for next V'. * Basically the trigger conditions are checked, when a task is activated. It is important to realize, that they are not checked, while a task is inactive. So you can not trigger to next logic 0 or logic 1 with overlapping offset and active video ranges between the tasks (e.g. task A STRC[2:0] = 2, YO[11:0] = 310 and task B STRC[2:0] = 3, YO[11:0] = 310 results in output field rate of 503 Hz). * After power-on or software reset (via SWRST[88H[5]]) task B gets priority over task A.
The task handler controls the switching between the two programming register sets. It is controlled by subaddresses 90H and C0H. A task is enabled via the global control bits TEA[80H[4]] and TEB[80H[5]]. The handler is then triggered by events, which can be defined for each register set. In case of a programming error the task handling and the complete scaler can be reset to the initial states by the software reset bit SWRST[88H[5]] at logic 0. Especially if the programming registers, related acquisition window and scale are reprogrammed, while a task is active, a software reset must be done after programming. Contrary to the disabling/enabling of a task, which is evaluated at the end of a running task, SWRST at logic 0 sets the internal state machines directly to their idle states. The start condition for the handler is defined by bits STRC[1:0]90H[1:0] and means: start immediately, wait for next V-sync, next FID at logic 0 or next FID at logic 1. The FID is evaluated, if the vertical and horizontal offsets are reached. With RPTSK[90H[2]] at logic 1 the actual running task is repeated (under the defined trigger conditions), before handing control over to the alternate task. To support field rate reduction, the handler is also enabled to skip fields (bits FSKP[2:0]90H[5:3]) before executing the task. A TOGGLE flag is generated (used for the correct output field processing), which changes state at the beginning of a task, every time a task is activated. Examples can be seen in Section 8.3.1.3.

8.3.1.3 Output field processing
SAA7114H
As reference for the output field processing, two signals are available for the back-end hardware. These signals are the input field ID from the scaler source and a TOOGLE flag, which shows, that an active task is used an odd (1, 3, 5...) or even (2, 4, 6...) number of times. Using a single or both tasks and reducing the field or frame rate with the task handling functionality, the TOGGLE information can be used, to reconstruct an interlaced scaled picture at a reduced frame rate. The TOGGLE flag isn't synchronized to the input field detection, as it is only dependent on the interpretation of this information by the external hardware, whether the output of the scaler is processed correctly (see Section 8.3.3). With OFIDC = 0, the scalers input field ID is available as output field ID on bit D6 of SAV and EAV, respectively on pin IGP0 (IGP1), if FID output is selected.
When OFIDC[90H[6]] = 1, the TOGGLE information is available as output field ID on bit D6 of SAV and EAV, respectively on pin IGP0 (IGP1), if FID output is selected. Additionally the bit D7 of SAV and EAV can be defined via CONLH[90H[7]]. CONLH[90H[7]] = 0 (default) sets D7 to logic 1, a logic 1 inverts the SAV/EAV bit D7. So it's possible to mark the output of the both tasks by different SAV/EAV codes. This bit can also be seen as `task flag' on the pins IGP0 (IGP1), if TASK output is selected.

8.3.2 HORIZONTAL SCALING
SAA7114H
The overall horizontal required scaling factor has to be split into a binary and a rational value according to the equation: output pixel H-scale ratio = ----------------------------input pixel 1 1024 H-scale ratio = --------------------------- x -----------------------------XPSC[5:0] XSCY[12:0] where, parameter of prescaler XPSC[5:0] = 1 to 63 and parameter of VPD phase interpolation XSCY[12:0] = 300 to 8191 (0 to 299 are only theoretical values). For example, 13.5 is to split in 14 x 1.14286. The binary factor is processed by the prescaler, the arbitrary non-integer ratios is achieved via the variable phase delay VPD circuitry, called horizontal fine scaling. Latter calculates horizontally interpolated new samples with a 6-bit phase accuracy, which relates to less than 1 ns jitter for regular sampling scheme. Prescaler and fine scaler are building the horizontal scaler of the SAA7114H. Using the accumulation length function of the prescaler (XACL[5:0]A1H[5:0]), application and destination dependent (e.g. scale for display or for a compression machine), a compromise between visible bandwidth and alias suppression can be found.
* The bit XC2_1[A2H[3]], which defines the weighting of the incoming pixels during the averaging process - XC2_1 = 0 1 + 1...+ 1 +1 - XC2_1 = 1 1 + 2...+ 2 +1 The prescaler builds a prescale dependent FIR low-pass, with up to (64 + 7) filter taps. The parameter XACL[5:0] can be used to vary the low-pass characteristic for a given integer prescale of 1XPSC[5:0]. The user can therewith decide between signal bandwidth (= sharpness impression) and alias. Equation for XPSC[5:0] calculation is: Npix_in XPSC[5:0] = lower integer of ---------------------Npix_out where, the range is 1 to 63 (value 0 is not allowed!); Npix_in = number of input pixel, and Npix_out = number of desired output pixel over the complete horizontal scaler. The use of the prescaler results in a XACL[5:0] and XC2_1 dependent gain amplification. The amplification can be calculated according to the equation: DC gain = ((XACL - XC2_1) + 1) x (XC2_1 + 1) It is recommended to use sequence lengths and weights, which results in a 2N DC gain amplification, as these amplitudes can be renormalized by the XDCG[2:0] 1 controlled ------ shifter of the prescaler. N 2 The renormalization range of XDCG[2:0] is 1, 12... down to 1 128. Other amplifications have to be normalized by using the following BCS control circuitry. In these cases the prescaler has to be set to an overall gain 1, e.g. for an accumulation sequence of `1 + 1 + 1' (XACL[5:0] = 2 and XC2_1 = 0), XDCG[2:0] must be set to `010', equals 14 and the BCS has to amplify the signal to 43 (SATN[7:0] and CONT[7:0] value = lower integer of 4 x 64). 3 The use of XACL[5:0] is XPSC[5:0] dependent. XACL[5:0] must be 2 x XPSC[5:0]. XACL[5:0] can be used to find a compromise between bandwidth (= sharpness) and alias effects.
8.3.2.1
Horizontal prescaler (subaddresses A0H to A7H and D0H to D7H)
The prescaling function consists of an FIR anti-alias filter stage and an integer prescaler, which is building an adaptive prescale dependent low-pass filter, to balance sharpness and aliasing effects. The FIR prefilter stage implements different low-pass characteristics to reduce alias for down-scales in the range of 1 to 12. A CIF optimized filter is build in, which reduces artefacts for CIF output formats (to be used in combination with the prescaler set to 12 scale). See Table 10. The functionality of the prescaler is defined by: * An integer prescaling ratio XPSC[5:0]A0H[5:0] (= 1 to 63), which covers the integer down-scale range 1 to 163 * An averaging sequence length XACL[5:0]A1H[5:0] (= 0 to 63); range 1 to 64 * A DC gain renormalization XDCG[2:0]A2H[2:0]; 1 down to 1128

Remark: Due to bandwidth considerations XPSC[5:0] and XACL[5:0] can be chosen different to the previous mentioned equations or Table 11, as the H-phase scaling is able to scale in the range from zooming up by factor 3 to down-scale by a factor of 10248191. Figs 26 and 27 show some resulting frequency characteristics of the prescaler. Table 11 shows the recommended prescaler programming. Other programmings, than documented in Table 11, may result in better alias suppression, but the resulting DC gain amplification needs to be compensated by the BCS control, according to the equation: 2 CONT[7:0] = SATN[7:0] = lower integer of --------------------------------DC gain x 64
XDG[2:0]
SAA7114H
Where: 2XDCG[2:0] DC gain DC gain = (XC2_1 + 1) x XACL[5:0] + (1 - XC2_1). For example, if XACL[5:0] = 5, XC2_1 = 1, then DC gain = 10 and the required XDCG[2:0] = 4. The horizontal source acquisition timing and the prescaling ratio is identical for both luminance path and chrominance path, but the FIR filter settings can be defined differently in the two channels. Fade-in and fade-out of the filters is achieved by copying an original source sample each as first and last pixel after prescaling. Figs 24 and 25 show the frequency characteristics of the selectable FIR filters.

8.3.2.2 Horizontal fine scaling (variable phase delay filter; subaddresses A8H to AFH and D8H to DFH) 8.3.3.1
SAA7114H
Line FIFO buffer (subaddresses 91H, B4H and C1H, E4H)
The horizontal fine scaling (VPD) should operate at scaling ratios between 12 and 2 (0.8 and 1.6), but can also be used for direct scale in the range from 17.999 to (theoretical) zoom 3.5 (restriction due to the internal data path architecture), without prescaler. In combination with the prescaler a compromise between sharpness impression and alias can be found, which is signal source and application dependent. For the luminance channel a filter structure with 10 taps is implemented, for the chrominance a filter with 4 taps. Luminance and chrominance scale increments (XSCY[12:0]A9H[4:0]A8H[7:0] and XSCC[12:0]ADH[4:0]ACH[7:0]) are defined independently, but must be set in a 2 : 1 relation in the actual data path implementation. The phase offsets XPHY[7:0]AAH[7:0] and XPHC[7:0]AEH[7:0] can be used to shift the sample phases slightly. XPHY[7:0] and XPHC[7:0] covers the phase offset range 7.999T to 132T. The phase offsets should also be programmed in a 2 : 1 ratio. The underlying phase controlling DTO has a 13-bit resolution. According to the equations Npix_in 1 XSCY[12:0] = 1024 x ------------------- x ---------------------- and XPSC Npix_out XSCY[12:0] XSCC[12:0] = ------------------------------ the VPD covers the scale 2 range from 0.125 to zoom 3.5. VPD acts equivalent to a polyphase filter with 64 possible phases. In combination with the prescaler, it is possible to get very accurate samples from a highly anti-aliased integer down-scaled input picture. 8.3.3 VERTICAL SCALING
The line FIFO buffer is a dual ported RAM structure for 768 pixels, with asynchronous write and read access. The line buffer can be used for various functions, but not all functions may be available simultaneously. The line buffer can buffer a complete unscaled active video line or more than one shorter lines (only for non-mirror mode), for selective repetition for vertical zoom-up. For zooming up 240 lines to 288 lines e.g., every fourth line is requested (read) twice from the vertical scaling circuitry for calculation. For conversion of a 4 : 2 : 0 or 4 : 1 : 0 input sampling scheme (MPEG, video phone, video YUV-9) to CCIR like sampling scheme 4 : 2 : 2, the chrominance line buffer is read twice of four times, before being refilled again by the source. By means of the input acquisition window definition it has to be preserved, that the processing starts with a line containing luminance and chrominance information for 4 : 2 : 0 and 4 : 1 : 0 input. The bits FSC[2:1]91H[2:1] are defining the distance between the Y/C lines. In case of 4 : 2 : 2 and 4 : 1 : 1 FSC2 to FSC1 have to be set to `00'. The line buffer can also be used for mirroring, i.e. for flipping the image left to right, for the vanity picture in video phone application (bit YMIR[B4H[4]]). In mirror mode only one active prescaled line can be held in the FIFO at a time. The line buffer can be utilized as excessive pipeline buffer for discontinuous and variable rate transfer conditions at expansion port or image port.
The vertical scaler of the SAA7114H consists of a line FIFO buffer for line repetition and the vertical scaler block, which implements the vertical scaling on the input data stream in 2 different operational modes from theoretical zoom by 64 down to icon size 164. The vertical scaler is located between the BCS and horizontal fine scaler, so that the BCS can be used to compensate the DC gain amplification of the ACM mode (see Section 8.3.3.2) as the internal RAMs are only 8-bit wide.

and field rate conversion are supported (i.e. de-interlacing, re-interlacing). Figs 28 and 29 and Tables 12 and 13 are describing the use of the offsets. Remark: The vertical start phase, as well as scaling ratio are defined independently for luminance and chrominance channel, but must be set to the same values in the actual implementation for accurate 4 : 2 : 2 output processing. The vertical processing communicates on it's input side with the line FIFO buffer. The scale related equations are: * Scaling increment calculation for ACM and LPI mode, down-scale and zoom: Nline_in YSCY(C)[15:0] = lower integer of 1024 x ------------------------ Nline_out * BCS value to compensate DC gain in ACM mode (contrast and saturation have to be set): CONT[7:0]A5H[7:0] respectively SATN[7:0]A6H[7:0] Nline_out = lower integer of ------------------------ x 64 , or Nline_in 1024 = lower integer of ------------------------------ x 64 YSCY[15:0]
Vertical scaling of any ratio from 64 (theoretical zoom) to 1 (icon) can be applied. 63 The vertical scaling block consists of another line delay, and the vertical filter structure, that can operate in two different modes. Called linear interpolation (LPI) and accumulation (ACM) mode, controlled by YMODE[B4H[0]]. * LPI mode: In Linear Phase Interpolation (LPI) mode (YMODE = 0) two neighbouring lines of the source video stream are added together, but weighted by factors corresponding to the vertical position (phase) of the target output line relative to the source lines. This linear interpolation has a 6-bit phase resolution, which equals 64 intra line phases. It interpolates between two consecutive input lines only. LPI mode should be applied for scaling ratios around 1 (down to 12), it must be applied for vertical zooming. * ACM mode: The vertical Accumulation (ACM) mode (YMODE = 1) represents a vertical averaging window over multiple lines, sliding over the field. This mode also generates phase correct output lines. The averaging window length corresponds to the scaling ration, resulting in an adaptive vertical low-pass effect, to greatly reduce aliasing artefacts. ACM can be applied for down-scales only from ratio 1 down to 164. ACM results in a scale dependent DC gain amplification, which has to be precorrected by the BCS control of the scaler part. The phase and scale controlling DTO calculates in 16-bit resolution, controlled by parameters YSCY[15:0]B1H[7:0]B0H[7:0] and YSCC[15:0]B3H[7:0]B2H[7:0], continuously over the entire filed. A start offset can be applied to the phase processing by means of the parameters YPY3[7:0] to YPY0[7:0] in BFH[7:0] to BCH[7:0] and YPC3[7:0] to YPC0[7:0] in BBH[7:0] to B8H[7:0]. The start phase covers the range of 25532 to 132 lines offset. By programming appropriate, opposite, vertical start phase values (subaddresses B8H to BFH and E8H to EFH) depending on odd/even field ID of the source video stream and A/B-page cycle, frame ID conversion
8.3.3.3
Use of the vertical phase offsets
As shown in Section 8.3.1.3, the scaler processing may run randomly over the interlaced input sequence. Additionally the interpretation and timing between ITU 656 field ID and real-time detection by means of the state of H-sync at falling edge of V-sync may result in different field ID interpretation. Also a vertically scaled interlaced output gets a larger vertical sampling phase error, if the interlaced input fields are processed, without regarding the actual scale at the starting point of operation (see Fig.28). Four events are to be considered, they are illustrated in Fig.29.

In Tables 12 and 13 PHO is a usable common phase offset. Please notice that the equations of Fig.29 are producing an interpolated output also for the unscaled case, as the geometrical reference position for all conversions is the position of the first line of the lower field (see Table 12). If there is no need for UP-LO and LO-UP conversion and the input field ID is the reference for the back-end operation, then it is UP-LO = UP-UP and LO-UP = LO-LO and the 12 line phase shift (PHO + 16) can be skipped. This case is listed in Table 13. The SAA7114H supports 4 phase offset registers per task and component (luminance and chrominance). The value of 20H represents a phase shift of one line.
SAA7114H
The registers are assigned to the following events; e.g. subaddresses B8H to BBH: * B8H: 00 = input field ID 0, task status bit 0 (toggle status, see Section 8.3.1.3) * B9H: 01 = input field ID 0, task status bit 1 * BAH: 10 = input field ID 1, task status bit 0 * BBH: 11 = input field ID 1, task status bit 1. Dependent on the input signal (interlaced or non-interlaced) and the task processing (50 Hz or field reduced processing with one or two tasks, see examples in Section 8.3.1.3), also other combinations may be possible, but the basic equations are the same.

8.4 VBI-data decoder and capture (subaddresses 40H to 7FH)
SAA7114H
The SAA7114H contains a versatile VBI-data decoder. The implementation and programming model accords to the VBI-data slicer built in the multimedia video data acquisition circuit SAA5284. The circuitry recovers the actual clock phase during the clock run-in period, slices the data bits with the selected data rate, and groups them to bytes. The result is buffered into a dedicated VBI-data FIFO with a capacity of 2 x 56 bytes (2 x 14 Dwords). The clock frequency, signals source, field frequency, accepted error count must be defined in subaddress 40H. The supported VBI-data standards are shown in Table 14. For lines 2 to 24 of a field, per VBI line, 1 of 16 standards can be selected (LCR24_[7:0] to LCR2_[7:0] in 57H[7:0] to 41H[7:0]: 23 x 2 x 4 bit programming bits). Table 14 Data types supported by the data slicer block DT[3:0] 62H[3:0] 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 1100 1101 1110 1111 US NABTS MOJI (Japanese) no sliced data transmitted (video data selected) 5.7272 5.7272 5 STANDARD TYPE teletext EuroWST, CCST European closed caption VPS wide screen signalling bits US teletext (WST) US closed caption (line 21) (video data selected) (raw data selected) teletext VITC/EBU time codes (Europe) VITC/SMPTE time codes (USA)
The definition for line 24 is valid for the rest of the corresponding field, normally no text data (= video data) should be selected there (LCR24_[7:0] = FFH) to stop the activity of the VBI-data slicer during active video. To adjust the slicers processing to the input signal source, there are offsets in horizontal and vertical direction available: parameters HOFF[10:0]5BH[2:0]59H[7:0], VOFF[8:0]5BH[4]5AH[7:0] and FOFF[5BH[7]]). Contrary to the scalers counting, the slicers offsets are defining the position of the H and V trigger events related to the processed video field. The trigger events are the falling edge of HREF and the falling edge of V123 from the decoder processing part. The relation of these programming values to the input signal and the recommended values can be seen in Tables 4 to 7.

8.5 Image port output formatter (subaddresses 84H to 87H)
SAA7114H
The bits VITX1 and VITX0 (subaddress 86H) are used to control the arbitration. As further operation the serialization of the internal 32-bit Dwords to 8-bit or optional 16-bit output, as well as the insertion of the extended ITU 656 codes (SAV/EAV for video data, ANC or SAV/EAV codes for sliced text data) are done here. For handshake with the VGA controller, or other memory or bus interface circuitry, programmable FIFO flags are provided (see Section 8.5.2). 8.5.1 SCALER OUTPUT FORMATTER (SUBADDRESSES 93H AND C3H)
The output interface consists of a FIFO for video and for sliced text data, an arbitration circuit, which controls the mixed transfer of video and sliced text data over the I-port and a decoding and multiplexing unit, which generates the 8 or 16-bit wide output data stream and the accompanied reference and supporting information. The clock for the output interface can be derived from an internal clock, decoder, expansion port, or an externally provided clock which is appropriate for e.g. VGA and frame buffer. The clock can be up to 33 MHz. The scaler provides the following video related timing reference events (signals), which are available on pins as defined by subaddresses 84H and 85H: * Output field ID * Start and end of vertical active video range, * Start and end of active video line * Data qualifier or gated clock * Actually activated programming page (if CONLH is used) * Threshold controlled FIFO filling flags (empty, full, filled) * Sliced data marker. The disconnected data stream at the scaler output is accompanied by a data valid flag (or data qualifier), or is transported via a gated clock. Clock cycles with invalid data on the I-port data bus (including the HPD pins in 16-bit output mode) are marked with code 00H. The output interface also arbitrates the transfer between scaled video data and sliced text data over the I-port output. Table 15 Byte stream for different output formats OUTPUT FORMAT YUV 4 : 2 : 2 YUV 4 : 1 : 1 Y only CB0 CB0 Y0 Y0 Y0 Y1 CR0 CR0 Y2
The output formatter organizes the packing into the output FIFO. The following formats are available: YUV 4 : 2 : 2, YUV 4 : 1 : 1, YUV 4 : 2 : 0, YUV 4 : 1 : 0, Y only (e.g. for raw samples). The formatting is controlled by FSI[2:0]93H[2:0], FOI[1:0]93H[4:3] and FYSK[93H[5]]. The data formats are defined on Dwords, or multiples, and are similar to the video formats as recommended for PCI multimedia applications (compare SAA7146A), but planar formats are not supported. FSI[2:0] defines the horizontal packing of the data, FOI[1:0] defines, how many Y only lines are expected, before a Y/C line will be formatted. If FYSK is set to logic 0 preceding Y only lines will be skipped, and output will always start with a Y/C line. Additionally the output formatter limits the amplitude range of the video data (controlled by ILLV[85H[5]]); see Table 17.

The video FIFO at the scaler output contains 32 Dwords. That corresponds to 64 pixels in 16-bit YUV 4 : 2 : 2 format. But as the entire scaler can act as pipeline buffer, the actually available buffer capacity for the image port is much higher, and can exceed beyond a video line. The image port, and the video FIFO, can operate with the video source clock (synchronous mode) or with externally provided clock (asynchronous, and burst mode), as appropriate for the VGA controller or attached frame buffer. The video FIFO provides 4 internal flags, reporting to which extent the FIFO is actually filled. These are: * The FIFO Almost Empty (FAE) flag * The FIFO Combined Flag (FCF) or FIFO filled, which is set at almost full level and reset, with hysteresis, only after the level crosses below the almost empty mark * The FIFO Almost Full (FAF) flag * The FIFO Overflow (FOVL) flag. The trigger levels for FAE and FAF are programmable by FFL[1:0]86H[3:2] (16, 24, 28, full) and FEL[1:0]86H[1:0] (16, 8, 4, empty). The state of this flag can be seen on the pins IGP0 or IGP1. The pin mapping is defined by subaddresses 84H and 85H (see Section 9.5). 8.5.3 TEXT FIFO
The decoded VBI-data is collected in the dedicated VBI-data FIFO. After capture of a line is completed, the FIFO can be streamed through the image port, preceded by a header, telling line number and standard. The VBI-data period can be signalled via the sliced data flag on pin IGP0 or IGP1. The decoded VBI-data is lead by the ITU ancillary data header (DID[5:0]5DH[5:0] at value <3EH) or by SAV/EAV codes selectable by DID[5:0] at value 3EH or 3FH. IGP0 or IGP1 is set, if the first byte of the ANC header is valid on the I-port bus. It is reset, if an SAV occurs. So it may frame multiple lines of text data output, in case video processing starts with a distance of several video lines to the region of text data. Valid sliced data from the text FIFO are available on the I-port as long as the IGP0 or IGP1 flag is set and the data qualifier is active on pin IDQ. The decoded VBI-data are presented in two different data formats, controlled by bit RECODE. * RECODE = 1: values 00H and FFH will be recoded to even parity values 03H and FCH * RECODE = 0: values 00H and FFH may occur in the data stream as detected. 8.5.4 VIDEO AND TEXT ARBITRATION (SUBADDRESS 86H)
In the text FIFO the data of the terminal VBI-data slicer are collected before the transmission over the I-port is requested (normally before the video window starts). It is partitioned into two FIFO sections. A complete line is filled into the FIFO, before a data transfer is requested. So normally, one line text data is ready for transfer, while the next text line is collected. So sliced text data are delivered as a block of qualified data, without any qualification gaps in the byte stream of the I-port.
Sliced text data and scaled video data are transferred over the same bus, the I-port. The mixed transfer is controlled by an arbitration circuitry. If the video data are transferred without any interrupt and the video FIFO does not need to buffer any output pixel, the text data are inserted after an end of a scaled video line, normally during the blanking interval of the video.

DATA STREAM CODING AND REFERENCE SIGNAL (SUBADDRESSES 84H, 85H AND 93H)
If ITU 656 like codes are not wanted, these codes can be suppressed in the output stream. As further option, it is possible to provide the scaler with a gating external signal on pin ITRDY. So it is possible to hold the data output for a certain time and to get valid output data in bursts of a guaranteed length. The sketched reference signals and events can be mapped to the I-port output pins IDQ, IGPH, IGPV, IGP0 and IGP1. For flexible use the polarities of all the outputs can be modified. The default polarity for the qualifier and reference signals is logic 1 (= active). Table 18 shows the relevant and supported SAV and EAV coding.
As H and V reference signals are logic 1, active gate signals are generated, which are framing the transfer of the valid output data. Alternative to the gates, H and V trigger pulses are generated on the rising edges of the gates. Due to the dynamic FIFO behaviour of the complete scaler path, the output signal timing has no fixed timing relation to the real-time input video stream. So fixed propagation delays, in therms of clock cycles, related to the analog input can not be defined. The data stream is accompanied by a data qualifier. Additionally invalid data cycles are marked with code 00H. Table 18 SAV/EAV codes on I-port

SAA7114H
* Audio master Clocks Nominal Increment, ACNI[21:0]36H[5:0]35H[7:0]34H[7:0] according to the audio frequency 23 equation: ACNI21:0] = round -------------------------------------------- x 2 crystal frequency See Table 21 for examples. Remark: For standard applications the synthesized audio clock AMCLK can be used directly as master clock and as input clock for port AMXCLK (short cut) to generate ASCLK and ALRCLK. For high-end applications it is recommended to use an external analog PLL circuit to enhance the performance of the generated audio clock.
SAA7114H incorporates generation of a field locked audio clock, as an auxiliary function for video capture. An audio sample clock, that is locked to the field frequency, makes sure that there is always the same predefined number of audio samples associated with a field, or a set of fields. That ensures synchronous playback of audio and video after digital recording (e.g. capture to hard disk), MPEG or other compression, or non-linear editing. 8.6.1 MASTER AUDIO CLOCK

SAA7114H
The SAA7114H has 5 different I/O interfaces: * Analog video input interface, for analog CVBS and/or Y and C input signals * Audio clock port * Digital real-time signal port (RT port) * Digital video expansion port (X-port), for unscaled digital video input and output * Digital image port (I-port) for scaled video data output and programming * Digital host port (H-port) for extension of the image port or expansion port from 8 to 16-bit.
The SAA7114H has 6 analog inputs AI21 to AI24, AI11 and AI12 for composite video CVBS or S-video Y/C signal pairs. Additionally, there are two differential reference inputs, which must be connected to ground via a capacitor equivalent to the decoupling capacitors at the 6 inputs. There are no peripheral components required other than these decoupling capacitors and 18 /56 termination resistors, one set per connected input signal (see also application example in Fig.40). Two anti-alias filters are integrated, and self adjusting via the clock frequency. Clamp and gain control for the two ADC's are also integrated. An analog video output pin AOUT is provided for testing purposes.

9.3 Clock and real-time synchronization signals
SAA7114H
For the generation of the line-locked video (pixel) clock LLC, and of the frame locked audio serial bit clock, a crystal accurate frequency reference is required. An oscillator is built in, for fundamental or third harmonic crystals. The supported crystal frequencies are 32.11 or 24.576 MHz (defined during reset by strapping pin ALRCLK). Alternatively pin XTALI can be driven from an external single ended oscillator. The crystal oscillation can be propagated as clock to other ICs in the system via pin XOUT. Table 25 Clock and real-time synchronization signals SYMBOL PIN I/O Crystal oscillator XTALI XTALO XOUT 7 6 4 I O O
The Line-Locked Clock (LLC) is the double pixel clock of nominal 27 MHz. It is locked to the selected video input, generating baseband video pixels according to "ITU recommendation 601". In order to support interfacing circuitries, a direct pixel clock LLC2 is also provided. The pins for line and field timing reference signals are RTCO, RTS1 and RTS0. Various real-time status information can be selected for the RTS pins. The signals are always available (output) and reflect the synchronization operation of the decoder part in the SAA7114H. The function of the RTS1 and RTS0 pins can be defined by bits RTSE1[3:0]12H[7:4] and RTSE0[3:0]12H[3:0].

9.4 Video expansion port (X-port)
SAA7114H
As output, these are direct copies of the decoder signals. The data transfers through the expansion port represent a single D1 port, with half duplex mode. The SAV and EAV codes may be inserted optionally for data input (controlled by bit XCODE[92H[3]]). The input/output direction is switched for complete fields, only.
The expansion port is intended for transporting video streams image data from other digital video circuits like MPEG encoder/decoder and video phone codec, to the image port (I-port). The expansion port consists of two groups of signals/pins: * 8-bit data, I/O, regularly components video YUV 4 : 2 : 2, i.e. CB-Y-CR-Y, byte serial, exceptionally raw video samples (e.g. ADC test). In input mode the data bus can be extended to 16-bit by the pins HPD7 to HPD0. * Clock, synchronization and auxiliary signals, accompanying the data stream, I/O.

9.4.1 X-PORT CONFIGURED AS OUTPUT
SAA7114H
If data output is enabled at the expansion port, then the data stream from the decoder is presented. The data format of the 8-bit data bus is dependent on the chosen data type, selectable by the line control registers LCR2 to LCR24; see Table 3. In contrast to the image port, the sliced data format is not available on the expansion port. Instead, raw CVBS samples are always transferred if any sliced data type is selected. Following are some details of data types on the expansion port: * Active video (data type 15) contains component YUV 4 : 2 : 2 signal, 720 active pixels per line. The amplitude and offsets are programmable via DBRI7 to DBRI0, DCON7 to DCON0, DSAT7 to DSAT0, OFFU1, OFFU0, OFFV1 and OFFV0. For nominal levels see Fig.17. * Test line (data type 6) is similar to active video format, with some constraints within the data processing: - adaptive chrominance comb filter, vertical filter (chrominance comb filter for NTSC standards, PAL phase error correction) within the chrominance processing are disabled - adaptive luminance comb filter, peaking and chrominance trap are bypassed within the luminance processing. This data type is defined for future enhancements. It could be activated for lines containing standard test signals within the vertical blanking period. Currently the most sources do not contain test lines. For nominal levels see Fig.17. * Raw samples (data types 0 to 5 and 7 to 14): UV-samples are similar to data type 6, but CVBS samples are transferred instead of processed luminance samples within the Y time slots. Table 27 Data format on the expansion port BLANKING PERIOD ... 80 TIMING REFERENCE CODE (HEX)(1)
The amplitude and offset of the CVBS signal is programmable via RAWG7 to RAWG0 and RAWO7 to RAWO0; see Chapter 15 "I2C-bus description", Tables 62 and 63. For nominal levels see Fig.18. The relation of LCR programming to line numbers is described in Section 8.2, see Tables 4 to 7. The data type selections by LCR are overruled by setting OFTS2 (subaddress 13H bit 2) = 1. This setting is mainly intended for device production test. The VPO-bus carries the upper or lower 8 bits of the two ADCs dependent on OFTS[1:0]13H[1:0] settings; see Table 57. The output configuration is done via MODE[3:0]02H[3:0] settings; see Table 39. If a YC mode is selected, the expansion port carries the multiplexed output signals of both ADCs, in CVBS mode the output of only one ADC. No timing reference codes are generated in this mode. Remark: The LSBs (bit 0) of the ADCs are also available on pin RTS0. For details see Table 55. The SAV/EAV timing reference codes define start and end of valid data regions. During horizontal blanking period between EAV and SAV the ITU-blanking code sequence `- 80 - 10 - 80 - 10 -...' is transmitted. The position of the F-bit is constant according to ITU 656 (see Tables 29 and 30). The V-bit can be generated in two different ways (see Tables 29 and 30) controlled via OFTS1 and OFTS0, see Table 57. F and V bits change synchronously with the EAV code.

Notes 1. The generation of the timing reference codes can be suppressed by setting OFTS[2:0] to `010', see Table 57. In this event the code sequence is replaced by the standard `- 80 - 10 -' blanking values. 2. If raw samples or sliced data are selected by the line control registers (LCR2 to LCR24), the Y-samples are replaced by CVBS samples.

SAA7114H
If data input mode is selected at the expansion port, then the scaler can choose it's input data stream from the on-chip video decoder, or from expansion port (controlled by bit SCSRC[1:0]91H[5:4]). Byte serial YUV 4 : 2 : 2, or subsets for other sampling schemes, or raw samples from an external ADC may be input (see also bits FSC[2:0]91H[2:0]). The input stream must be accompanied by an external clock XCLK, qualifier XDQ and reference signals XRH and XRV. Instead of the reference signal, embedded SAV and EAV codes according to ITU 656 are also accepted. The protection bits are not evaluated. XRH and XRV carry the horizontal and vertical synchronization signals for the digital video stream through the expansion port. The field ID of the input video stream is carried in the phase (edge) of XRV and state of XRH, or directly as FS (frame sync, odd/even signal) on the XRV pin (controlled by XFDV[92H[7]], XFDH[92H[6]] and XDV1[92H[5]]). The trigger events on XRH (rising/falling edge) and XRV (rising/falling/both edges) for the scalers acquisition window are defined by XDV[1:0]92H[5:4] and XDH[92H[2]]. Also the signal polarity of the qualifier can be defined (bit XDQ[92H[1]]). Alternatively to a qualifier, the input clock can be applied to a gated clock (means clock gated with a data qualifier, controlled by bit XCKS[92H[0]]). In this event, all input data will be qualified. 9.5 Image port (I-port)
For handshake with the receiving VGA controller, or other memory or bus interface circuitry, F, H and V reference signals and programmable FIFO flags are provided. The information will be provided on pins IGP0, IGP1, IGPH and IGPV. The functionality on this pins is controlled via subaddresses 84H and 85H. VBI-data is collected over an entire line in its own FIFO, and transferred as an uninterrupted block of bytes. Decoded VBI-data can be signed by the VBI flag on pin IGP0/1. As scaled video data and decoded VBI-data may come from different and asynchronous sources, an arbitration scheme is needed. Normally VBI-data slicer has priority. The image port consists of the pins and/or signals, as listed in Table 31. For pin constrained applications, or interfaces, the relevant timing and data reference signals can also get encoded into the data stream. Therefore the corresponding pins do not need to get connected. The minimum image port configuration requires 9 pins only, i.e. 8 pins for data including codes, and 1 pin for clock or gated clock. The inserted codes are defined in close relation to the ITU/CCIR-656 (D1) recommendation, where possible. The following deviations from "ITU 656 recommendation" are implemented at SAA7114H's image port interface: * SAV and EAV codes are only present in those lines, where data is to be transferred, i.e. active video lines, or VBI-raw samples, no codes for empty lines * There may be more or less than 720 pixels between SAV and EAV * Data content and number of clock cycles during horizontal and vertical blanking is undefined, and may be not constant * Data stream may be interleaved with not-valid data codes, 00H, but SAV and EAV 4-byte codes are not interleaved with not-valid data codes * There may be an irregular pattern of not-valid data, or IDQ, and as a result, `CB - Y - CR - Y -' is not in a fixed phase to a regular clock divider
The image port transfers data from the scaler as well as from the VBI-data slicer, if so selected (maximum 33 MHz). The reference clock is available at the ICLK pin, as output, or as input (maximum 33 MHz). As output, ICLK is derived from the locked decoder or expansion port input clock. The data stream from the scaler output is normally discontinuous. Therefore valid data during a clock cycle is accompanied by a data qualifying (data valid) flag on pin IDQ. For pin constrained applications the IDQ pin can be programmed to function as gated clock output (bit ICKS2[80H[2]]). The data formats at the image port are defined in Dwords of 32 bits (4 bytes), like the related FIFO structures. But the physical data stream at the image port is only 16-bit or 8-bit wide; in 16-bit mode data pins HPD7 to HPD0 are used for chrominance data. The four bytes of the Dwords are serialized in words or bytes.

Basic input and output timing diagrams I-port and X-port I-PORT OUTPUT TIMING
The following diagrams are sketching the output timing via the I-port. IGPH and IGPV are sketched as logic 1 active gate signals. If reference pulses are programmed, these pulses are generated on the rising edge of the logic 1 active gates. Valid data is accompanied by the output data qualifier on pin IDQ. In addition invalid cycles are marked with output code 00H. The IDQ output pin may be defined to be a gated clock output signal (ICLK AND internal IDQ). 9.7.2 X-PORT INPUT TIMING
At the X-port the input timing requirements are the same as sketched for the I-port output. But different to this: * It is not necessary to mark invalid cycles with a 00H code * No constraints on the input qualifier (can be a random pattern) * XCLK may be a gated clock (XCLK AND external XDQ). Remark: All timings illustrated in Figs 31 to 37 are given for an uninterrupted output stream (no handshake with the external hardware).

10 BOUNDARY SCAN TEST The SAA7114H has built in logic and 5 dedicated pins to support boundary scan testing which allows board testing without special hardware (nails). The SAA7114H follows the "IEEE Std. 1149.1 - Standard Test Access Port and Boundary-Scan Architecture" set by the Joint Test Action Group (JTAG) chaired by Philips. The 5 special pins are Test Mode Select (TMS), Test Clock (TCK), Test Reset (TRST), Test Data Input (TDI) and Test Data Output (TDO). Table 33 BST instructions supported by the SAA7114H INSTRUCTION BYPASS EXTEST SAMPLE DESCRIPTION
SAA7114H
The Boundary Scan Test (BST) functions BYPASS, EXTEST, INTEST, SAMPLE, CLAMP and IDCODE are all supported (see Table 33). Details about the JTAG BST-TEST can be found in the specification "IEEE Std. 1149.1". A file containing the detailed Boundary Scan Description Language (BSDL) description of the SAA7114H is available on request.
This mandatory instruction provides a minimum length serial path (1 bit) between TDI and TDO when no test operation of the component is required. This mandatory instruction allows testing of off-chip circuitry and board level interconnections. This mandatory instruction can be used to take a sample of the inputs during normal operation of the component. It can also be used to preload data values into the latched outputs of the boundary scan register. This optional instruction is useful for testing when not all ICs have BST. This instruction addresses the bypass register while the boundary scan register is in external test mode. This optional instruction will provide information on the components manufacturer, part number and version number. This optional instruction allows testing of the internal logic (no customer support available). This private instruction allows testing by the manufacturer (no customer support available). When the IDCODE instruction is loaded into the BST instruction register, the identification register will be connected between TDI and TDO of the IC. The identification register will load a component specific code during the CAPTURE_DATA_REGISTER state of the TAP controller and this code can subsequently be shifted out. At board level this code can be used to verify component manufacturer, type and version number. The device identification register contains 32 bits, numbered 31 to 0, where bit 31 is the most significant bit (nearest to TDI) and bit 0 is the least significant bit (nearest to TDO); see Fig.38.
CLAMP IDCODE INTEST USER1 10.1
Initialization of boundary scan circuit
The TAP (Test Access Port) controller of an IC should be in the reset state (TEST_LOGIC_RESET) when the IC is in functional mode. This reset state also forces the instruction register into a functional instruction such as IDCODE or BYPASS. To solve the power-up reset, the standard specifies that the TAP controller will be forced asynchronously to the TEST_LOGIC_RESET state by setting the TRST pin LOW. 10.2 Device identification codes
A device identification register is specified in "IEEE Std. 1149.1b-1994". It is a 32-bit register which contains fields for the specification of the IC manufacturer, the IC part number and the IC version number. Its biggest advantage is the possibility to check for the correct ICs mounted after production and determination of the version number of ICs during field service.

16.4 Scaler and interfaces 16.4.1 TRIGGER CONDITION
SAA7114H
Table 130 shows some examples for the scaler programming with: * prsc = prescale ratio * fisc = fine scale ratio * vsc = vertical scale ratio. number of input pixel The ratio is defined as: ---------------------------------------------------------number of output pixel In the following settings the VBI-data slicer is inactive. To activate the VBI-data slicer, VITX[1:0]86H[7:6] has to be set to `11'. Dependent on the VBI-data slicer settings, the sliced VBI-data are inserted after end of scaled video lines, if the regions of VBI-data slicer and scaler overlaps. To compensate the running-in of the vertical scaler, the vertical input window lengths are extended by 2 to 290 lines, respectively 242 lines for XS, but the scaler increment calculations are done with 288, respectively 240 lines. 16.4.3 EXAMPLES
For trigger condition STRC[1:0]90H[1:0] not equal `00'. If the value of (YO + YS) is greater equal 262 (NTSC), respectively 312 (PAL) the output field rate is reduced to 30 Hz, respectively 25 Hz. Horizontal and vertical offsets (XO and YO) have to be used to adjust the displayed video in the display window. As this adjustment is application dependent, the listed values are only dummy values. 16.4.2 MAXIMUM ZOOM FACTOR
The maximum zoom factor is dependent on the back-end data rate and therefore back-end clock and data format dependent (8 or 16-bit output). The maximum horizontal zoom is limited to about 3.5, due to internal data path restrictions.

18 SOLDERING 18.1 Introduction to soldering surface mount packages
SAA7114H
* For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 18.4 Manual soldering
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. 18.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 230 C. 18.3 Wave soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave.

REFLOW(1)
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
