saa7129h 7 functional description the digital video encoder encodes digital luminance and colour difference signals into analog cvbs, s-video and simultaneously rgb or c r -y-c b signals. ntsc-m, pal b/g, secam and sub-standards are supported. both interlaced and non-interlaced operation is possible for all standards. the basic encoder function consists of subcarrier generation and colour modulation and insertion of synchronization signals. luminance and chrominance signals are filtered in accordance with the standard requirements of rs-170-a and itu-r bt.470-3 . for ease of analog post filtering the signals are twice oversampled with respect to the pixel clock before digital-to-analog conversion. the total filter transfer characteristics are illustrated in figs 8 to 13. the dacs for y, c and cvbs are realized with full 10-bit resolution; 9-bit resolution for rgb output. the c r -y-c b to rgb dematrix can be bypassed optionally in order to provide the upsampled c r -y-c b input signals. the 8-bit multiplexed c b -y-c r formats are itu-r bt.656 (d1 format) compatible, but the sav and eav codes can be decoded optionally, when the device is operated in slave mode. two independent data streams can be processed, one latched by the rising edge of llc1, the other latched by the falling edge of llc1. the purpose of that is e.g. to forward one of the data streams containing both video and on-screen display (osd) information to the rgb outputs, and the other stream containing video only to the encoded outputs cvbs and s-video. for optimum display of rgb signals through a euro-connector tv set, optionally on the cvbs output an early composite sync pulse (up to 31 llc1 clock periods) can be provided. as a further alternative, the vbs and c outputs may provide a second and third cvbs signal. it is also possible to connect a philips digital video decoder (saa7111, saa7711a, saa7112 or saa7151b) to the SAA7128H; saa7129h. via the rtci pin, connected to rtco of a decoder, information concerning actual subcarrier, pal-id and (with saa7111 and newer types) definite subcarrier phase can be inserted. the device synthesizes all necessary internal signals, colour subcarrier frequency, and synchronization signals, from that clock. wide screen signalling data can be loaded via the i 2 c-bus and is inserted into line 23 for standards using 50 hz field rate. vps data for program dependent automatic start and stop of such featured vcrs is loadable via i 2 c-bus. the ic also contains closed caption and extended data services encoding (line 21), and supports anti-taping signal generation in accordance with macrovision. it is also possible to load data for copy generation management system into line 20 of every field (525/60 line counting). a number of possibilities are provided for setting different video parameters such as: black and blanking level control colour subcarrier frequency variable burst amplitude etc. during reset ( reset = low) and after reset is released, all digital i/o stages are set to input mode and the encoder is set to pal mode and outputs a black burst signal on cvbs and s-video outputs, while rgb outputs are set to their lowest output voltages. a reset forces the i 2 c-bus interface to abort any running bus transfer. 7.1 versatile fader important note: whenever the fader is activated with the symp bit set to a logic 1 (enabling the detection of embedded start of active video (sav) and end of active video (eav)), codes 00h and ffh are not allowed within the actual video data (as prescribed by itu-r bt. 656, anyway). if sav (00h) has been detected, the fader automatically passes 100% of the respective signal until sav will be detected. within the digital video encoder, two data streams can be faded against each other; these data streams can be input to the double speed mpeg port, which is able to separate two independent 27 mhz data streams mp a and mp b via a cross switch controlled by edge1 and edge2. handbook, halfpage mhb574 mp a mp b mp pos mp neg edge1 = 0 edge1 = 1 edge2 = 1 edge2 = 0 fig.3 cross switch. 2000 mar 08 9 philips semiconductors product speci?cation digital video encoder SAA7128H; saa7129h 7.1.1 c onfiguration examples figs 4 to 7 show examples on how to configure the fader between the input ports and the outputs, separated into the composite (and s-video) encoder and the rgb encoder. 7.1.1.1 con?guration 1 input mp a can be faded into mp b . the resulting output of the fader is then encoded simultaneously to composite (and s-video) and rgb output (rgbin = encin = 1). in this example, either mp a or mp b could be an overlay (menu) signal to be faded smoothly in and out. 7.1.1.2 con?guration 2 input mp a can be faded into mp b . the resulting output of the fader is then encoded to rgb output, while the signal coming from mp b is fed directly to composite (and s-video) output (rgbin = 1, encin = 0). also in this example, either mp a or mp b could be an overlay (menu) signal to be faded smoothly in and out, whereas the overlay appears only in the rgb output connected to the tv set. 7.1.1.3 con?guration 3 input mp b is passed directly to the rgb output, assuming e.g. it contains video including overlay. mp a is equivalently passed through the inactive fader to the composite (and s-video) output, assuming e.g. it contains video excluding overlay (rgbin = 0, encin = 1). 7.1.1.4 con?guration 4 only mp b input is in use; its signal appears both composite (and s-video) and rgb encoded (rgbin = encin = 0). mhb575 encoder path rgb path fader output mp a mp b mp e.g. video recorder e.g. tv vp fig.4 configuration 1. mhb576 encoder path rgb path fader output mp a mp b mp e.g. tv vp e.g. video recorder fig.5 configuration 2. mhb577 encoder path rgb path fader bypass mp a mp b e.g. tv e.g. video recorder fig.6 configuration 3. handbook, halfpage mhb578 encoder path rgb path mp a mp b e.g. video recorder e.g. tv fig.7 configuration 4. 2000 mar 08 10 philips semiconductors product speci?cation digital video encoder SAA7128H; saa7129h 7.1.2 p arameters of the fader basically, there are three independent fade factors available, allowing for the equation: where x = 1, 2 or 3 factor fade1 is effective, when a colour in the data stream fed to the mpeg port fader input is recognized as being between key1l and key1u. that means, the colour is not identified by a single numeric value, but an upper and lower threshold in a 24-bit yuv colour space can be defined. fade1 = 00h results in 100% signal at the mpeg port fader input and 0% signal at the fader video port input. variation of 63 steps is possible up to fade1 = 3fh, resulting in 0% signal at the mpeg port fader input and 100% signal at the fader video port input. factor fade2 is effective, when a colour in the data stream fed to the mpeg port fader input is recognized as being between key2l and key2u. fade2 is to be seen in conjunction with a colour that is defined by a 24-bit internal colour look-up table (clut). fade2 = 00h results in 100% of the internally defined lut colour and 0% signal at the fader video port input. variation of 63 steps is possible up to fade2 = 3fh, resulting in 0% of the internally defined lut colour and 100% signal at the fader video port input. finally, factor fade3 is effective, when a colour in the data stream fed to the mpeg port fader input is recognized as neither being between key1l and key1u nor being between key2l and key2h. fade3 = 00h results in 100% signal at the mpeg port fader input and 0% signal at the fader video port input. variation of 63 steps is possible up to fade3 = 3fh, resulting in 0% signal at the mpeg port fader input and 100% signal at the fader video port input. optionally, all upper and lower thresholds can be ignored, enabling to fade signals only against the lut colour. if bit cfadm is set high, all data at the mpeg port fader are faded against the lut colour, if bit cfadv is set high, all data at the video port fader are faded against the lut colour. 7.2 data manager in the data manager, alternatively to the external video data, a pre-defined colour look-up table located in this block can be read out in a pre-defined sequence (8 steps per active video line), achieving a colour bar test pattern generator without the need for an external data source. 7.3 encoder 7.3.1 v ideo path the encoder generates out of y, u and v baseband signals luminance and colour subcarrier output signals, suitable for use as cvbs or separate y and c signals. luminance is modified in gain and in offset (latter programmable in a certain range to enable different black level set-ups). after insertion of a fixed synchronization pulse tip level, in accordance with standard composite synchronization schemes, a blanking level can be set. other manipulations used for the macrovision anti-taping process like additional insertion of agc super-white pulses (programmable in height) are supported by SAA7128H only. in order to enable easy analog post filtering, luminance is interpolated from 13.5 mhz data rate to 27 mhz data rate, providing luminance in 10-bit resolution. the transfer characteristics of the luminance interpolation filter are illustrated in figs 10 and 11. appropriate transients at start/end of active video and for synchronization pulses are ensured. chrominance is modified in gain (programmable separately for u and v), standard dependent burst is inserted, before baseband colour signals are interpolated from 6.75 mhz data rate to 27 mhz data rate. one of the interpolation stages can be bypassed, thus providing a higher colour bandwidth, which can be made use of for y and c output. the transfer characteristics of the chrominance interpolation filter are illustrated in figs 8 and 9. the amplitude, beginning and ending of the inserted burst, is programmable in a certain range that is suitable for standard signals and for special effects. behind the succeeding quadrature modulator, colour in 10-bit resolution is provided on subcarrier. the numeric ratio between y and c outputs is in accordance with the respective standards. output fadex ln1 () 1 fadex C () ln2 [] + = 2000 mar 08 11 philips semiconductors product speci?cation digital video encoder SAA7128H; saa7129h 7.3.2 t eletext insertion and encoding pin ttx receives a wst or nabts teletext bitstream sampled at the llc clock. two protocols are provided: at each rising edge of output signal (ttxrq) a single teletext bit has to be provided after a programmable delay at input pin ttx the signal ttxrq performs only a single low-to-high transition and remains at high level for 360, 296 or 288 teletext bits, depending on the chosen standard. phase variant interpolation is achieved on this bitstream in the internal teletext encoder, providing sufficient small phase jitter on the output text lines. ttxrq provides a fully programmable request signal to the teletext source, indicating the insertion period of bitstream at lines which are selectable independently for both fields. the internal insertion window for text is set to 360 (pal-wst), 296 (ntsc-wst) or 288 (nabts) teletext bits including clock run-in bits. the protocol and timing are illustrated in fig.23. 7.3.3 v ideo p rogramming s ystem (vps) encoding five bytes of vps information can be loaded via the i 2 c-bus and will be encoded in the appropriate format into line 16. 7.3.4 c losed caption encoder using this circuit, data in accordance with the specification of closed caption or extended data service, delivered by the control interface, can be encoded (line 21). two dedicated pairs of bytes (two bytes per field), each pair preceded by run-in clocks and framing code, are possible. the actual line number where data is to be encoded in, can be modified in a certain range. the data clock frequency is in accordance with the definition for ntsc-m standard 32 times horizontal line frequency. data low at the output of the dacs corresponds to 0 ire, data high at the output of the dacs corresponds to approximately 50 ire. it is also possible to encode closed caption data for 50 hz field frequencies at 32 times horizontal line frequency. 7.3.5 a nti - taping (SAA7128H only ) for more information contact your nearest philips semiconductors sales office. 7.4 rgb processor this block contains a dematrix in order to produce red, green and blue signals to be fed to a scart plug. before y, c b and c r signals are de-matrixed, individual gain adjustment for y and colour difference signals and 2 times oversampling for luminance and 4 times oversampling for colour difference signals is performed. the transfer curves of luminance and colour difference components of rgb are illustrated in figs 12 and 13. 7.5 secam processor secam specific pre-processing is achieved in this block by a pre-emphasis of colour difference signals (for gain and phase see figs 14 and 15). a baseband frequency modulator with a reference frequency shifted from 4.286 mhz to dc carries out secam modulation in accordance with appropriate standard or optionally wide clipping limits. after the hf pre-emphasis, also applied on a dc reference carrier (anti-cloche filter; see figs 16 and 17), line-by-line sequential carriers with black reference of 4.25 mhz (db) and 4.40625 mhz (dr) are generated using specified values for fsc programming bytes. alternating phase reset in accordance with secam standard is carried out automatically. during vertical blanking the so-called bottle pulses are not provided. 7.6 output interface/dacs in the output interface, encoded y and c signals are converted from digital-to-analog in a 10-bit resolution. y and c signals are also combined to a 10-bit cvbs signal. the cvbs output occurs with the same processing delay (equal to 82 llc clock periods, measured from mp input to the analog outputs) as the y, c and rgb outputs. absolute amplitude at the input of the dac for cvbs is reduced by 15 16 with respect to y and c dacs to make maximum use of conversion ranges. red, green and blue signals are also converted from digital-to-analog, each providing a 9-bit resolution. outputs of the dacs can be set together via software control to minimum output voltage (approximately 0.2 v dc) for either purpose. alternatively, the buffers can be switched into 3-state output condition; this allows for wired anding with other 3-state outputs and can also be used as a power-save mode. 2000 mar 08 12 philips semiconductors product speci?cation digital video encoder SAA7128H; saa7129h 7.7 synchronization the synchronization of the SAA7128H; saa7129h is able to operate in two modes; slave mode and master mode. in master mode (see fig.19), the circuit generates all necessary timings in the video signal itself, and it can provide timing signals at the rcv1 and rcv2 ports. in slave mode, it accepts timing information either from the rcv pins or from the embedded timing data of the itu-r bt.656 data stream. for the SAA7128H; saa7129h, the only difference between master and slave mode is that it ignores the timing information at its inputs in master mode. thus, if in slave mode, any timing information is missing, the ic will continue running free without a visible effect. but there must not be any additional pulses (with wrong phase) because the circuit will not ignore them. in slave mode (see fig.18), an interface circuit decides, which signal is expected at the rcv1 port and which information is taken from its active slope. the polarity can be chosen, if prcv1 is logic 0 the rising slope will be active. the signal can be: a vertical sync (vs) pulse; the active slope sets the vertical phase an odd/even signal; the active slope sets the vertical phase, the internal field flag to odd and optionally sets the horizontal phase a field sequence (fseq) signal; it marks the first field of the 4 (ntsc), 8 (pal) respectively 12 (secam) field sequence. in addition to the odd/even signal, it also sets the pal phase and optionally defines the subcarrier phase. on the rcv2 port, the ic can provide a horizontal pulse with programmable start and stop phase; this pulse can be inhibited in the vertical blanking period to build up, for example, a composite blanking signal. the horizontal phase can be set via a separate input rcv2. in the event of vs pulses at rcv1, this is mandatory. it is also possible to set the signal path to blank via this input. from the itu-r bt.656 data stream, the SAA7128H; saa7129h decodes only the start of the first line in the odd field. all other information is ignored and may miss. if this kind of slave mode is active, the rcv pins may be switched to output mode. in slave mode, the horizontal trigger phase can be programmed to any point in the line, the vertical phase from line 0 to line 15 counted from the first serration pulse in half line steps. whenever synchronization information cannot be derived directly from the inputs, the SAA7128H; saa7129h will calculate it from the internal horizontal, vertical and pal phase. this gives good flexibility with respect to external synchronization but the circuit does not suppress illegal settings. in such an event, e.g the odd/even information may vanish as it does in the non-interlaced modes. in master mode, the line lengths are fixed to 1728 clocks at 50 hz and 1716 clocks at 60 hz. to allow non-interlaced frames, the field lengths can be varied by 0.5 lines. in the event of non-interlace, the SAA7128H; saa7129h does not provide odd/even information and the output signal does not contain the pal bruch sequence. at the rcv1 pin the ic can provide: a vertical sync (vs) signal with 2.5 (50 hz) or 3 (60 hz) lines duration an odd/even signal which is low in odd fields a field sequence (fseq) signal which is high in the first field of the 4, 8 respectively 12 field sequence. at the rcv2 pin, there is a horizontal pulse of programmable phase and duration available. this pulse can be suppressed in the programmable inactive part of a field giving a composite blank signal. the directions and polarities of the rcv ports can be chosen independently. timing references can be found in tables 52 and 60. 7.8 clock the input to llc1 can either be an external clock source or the buffered on-chip clock xclk. the internal crystal oscillator can be run with either a 3rd-harmonic or a fundamental crystal. 7.9 i 2 c-bus interface the i 2 c-bus interface is a standard slave transceiver, supporting 7-bit slave addresses and 400 kbits/s guaranteed transfer rate. it uses 8-bit subaddressing with an auto-increment function. all registers are write and readable, except one read only status byte. the i 2 c-bus slave address is defined as 88h with pin 21 (sa) tied low and as 8ch with pin 21 (sa) tied high. 2000 mar 08 13 philips semiconductors product speci?cation digital video encoder SAA7128H;

saa7129h 8.1 explanation of rtci data bits 1. the hpll increment is not evaluated by the SAA7128H; saa7129h. 2. the SAA7128H; saa7129h generates the subcarrier frequency from the fscpll increment if enabled (see item 7). 3. the pal bit indicates the line with inverted (r - y) component of colour difference signal. 4. if the reset bit is enabled (rtce = 1; decph = 1; phres = 00), the phase of the subcarrier is reset in each line whenever the reset bit of rtci input is set to logic 1. 5. if the fise bit is enabled (rtce = 1; decfis = 1), the SAA7128H; saa7129h takes this bit instead of the fise bit in subaddress 61h. 6. if the odd/even bit is enabled (rtce = 1; decoe = 1), the SAA7128H; saa7129h ignores its internally generated odd/even flag and takes the odd/even bit from rtci input. 7. if the colour detection bit is enabled (rtce = 1; deccol = 1) and no colour was detected (colour detection bit = 0), the subcarrier frequency is generated by the SAA7128H; saa7129h. in the other case (colour detection bit = 1) the subcarrier frequency is evaluated out of fscpll increment. if the colour detection bit is disabled (rtce = 1; deccol = 0), the subcarrier frequency is evaluated out of fscpll increment, independent of the colour detection bit of rtci input. handbook, full pagewidth 128 13 14 19 67 64 69 72 74 68 01 0 0 22 rtci hpll increment (1) fscpll increment (2) high-to-low transition count start 4 bits reserved valid sample invalid sample not used in SAA7128H/29h 3 bits reserved 8/llc mgl934 low time slot: (3) (4) (6) (7) (8) (5) fig.22 rtci timing.

soldering 11.1 introduction to soldering surface mount packages 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. 11.2 re?ow 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. 11.3 wave soldering 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. for packages with leads on two sides and a pitch (e): C 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; C 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. 11.4 manual 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. 2000 mar 08 52 philips semiconductors product speci?cation digital video encoder SAA7128H; saa7129h 11.5 suitability of surface mount ic packages for wave and re?ow soldering methods notes 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. package soldering method wave
