DESCRIPTION The TDA9113 is a monolithic integrated circuit assembled in a 32-pin shrink dual-in-line plastic package. This IC controls all the functions related to horizontal and vertical deflection in multimode or multi-frequency computer display monitors. The internal sync processor, combined with the powerful geometry correction block, makes the TDA9113 suitable for very high performance monitors, using few external components. Combined with other ST components dedicated for CRT monitors (microcontroller, video preamplifier, video amplifier, OSD controller) the TDA9113 allows fully I2C bus-controlled computer display monitors to be built with a reduced number of external components.

Note 1: Frequency at no sync signal condition. For correct operation, the frequency of the sync signal applied must always be higher than the free-running frequency. The application must consider the spread of values of real electrical components in RRO and CCO positions so as to always meet this condition. The formula to calculate the free-running frequency is fHO(0)=0.12125/(RRO CCO) Note 2: Base of NPN transistor with emitter to ground is internally connected on pin HFly through a series resistance of about 500 and a resistance to ground of about 20k. Note 3: Evaluated and figured out during the device qualification phase. Informative. Not tested on every single unit. Note 4: This capture range can be enlarged by external circuitry. Note 5: The voltage on HPLL2C pin corresponds to immediate phase of leading edge of H-drive signal on HOut pin with respect to internal horizontal oscillator sawtooth. It must be between the two clamping levels given. Voltage equal to one of the clamping values indicates a marginal operation of PLL2 or non-locked state. Note 6: Internal threshold. See Figure 10. Note 7: The tph(min)/TH parameter is fixed by the application. For correct operation of asymmetry corrections through dynamic phase modulation, this minimum must be increased by maximum of the total dynamic phase required in the direction leading to bending of corners to the left. Marginal situation is indicated by reach of VTopHPLL2C high clamping level by waveform on pin HPLL2C. Also refer to Note 5 and Figure 10. Note 8: The tph(max)/TH parameter is fixed by the application. For correct operation of asymmetry corrections through dynamic phase modulation, this maximum must be reduced by maximum of the total dynamic phase required in the direction leading to bending of corners to the right. Marginal situation is indicated by reach of VBotHPLL2C low clamping level by waveform on pin HPLL2C. Also refer to Note 5 and Figure 10 . Note 9: All other dynamic phase corrections of picture asymmetry set to their neutral (medium) positions.

9 - OPERATING DESCRIPTION 9.1 - SUPPLY AND CONTROL
9.1.1 - Power supply and voltage references The device is designed for a typical value of power supply voltage of 12 V. In order to avoid erratic operation of the circuit at power supply ramp-up or ramp-down, the value of VCC is monitored. See Figure 1 and electrical specifications. At switch-on, the device enters a "normal operation" as the supply voltage exceeds VCCEn and stays there until it decreases bellow VCCDis. The two thresholds provide, by their difference, a hysteresis to bridge potential noise. Outside the "normal operation", the signals on HOut, BOut and VOut outputs are inhibited and the I2C bus interface is inactive (high impedance on SDA, SCL pins, no ACK), all I2C bus control registers being reset to their default values (see chapter I2C BUS CONTROL REGISTER MAP on page 22).

The device supports multiple data byte messages (with automatic incrementation of the I2C bus subaddress) as well as repeated Start Condition for I2C bus subaddress change inside the I2C bus messages. All I2C bus registers with specified I2C bus subaddress are of WRITE ONLY type, whereas the status register providing a feedback information to the master I2C bus device has no attributed I2C bus subaddress and is of READ ONLY type. The master I2C bus device reads this register sending directly, after the Start Condition, the READ device I2C bus slave address (8D) followed by the register read-out, NAK (No Acknowledge) signal and the Stop Condition. For the I2C bus control register map, refer to chapter I2C BUS CONTROL REGISTER MAP on page 22.
9.2 - SYNC. PROCESSOR
9.2.1 - Synchronization signals The device has two inputs for TTL-level synchronization signals, both with hysteresis to avoid erratic detection and with a pull-down resistor. On H/ HVSyn input, pure horizontal or composite horizontal/vertical signal is accepted. On VSyn input, only pure vertical sync. signal is accepted. Both positive and negative polarities may be applied on either input, see Figure 2. Polarity detector and programmable inverter are provided on each of the two inputs. The signal applied on H/HVSyn pin, after polarity treatment, is directly lead to horizontal part and to an extractor of vertical sync. pulses, working on principle of integration, see Figure 3. The vertical sync. signal applied to the vertical deflection processor is selected between the signal extracted from the composite signal on H/HVSyn input and the one applied on VSyn input. The selector is controlled by VSyncSel I2C bus bit. Besides the polarity detection, the device is capable of detecting the presence of sync. signals on each of the inputs and at the output of vertical sync. extractor. The information from all detectors is provided in the I2C bus status register (5 flags: VDet, HVDet, VExtrDet, VPol, HVPol). The device is equipped with an automatic mode (switched on or off by VSyncAuto I2C bus bit) that also uses the detection information.

Internal thresholds in all parts of the circuit are derived from a common internal reference supply VRefO that is lead out to RefOut pin for external filtering against ground as well as for external use with load currents limited to IRefO. The filtering is necessary to minimize interference in output signals, causing adverse effects like e.g. jitter. 9.1.2 - I2C Bus Control The I2C bus is a 2 line bi-directional serial communication bus introduced by Philips. For its general description, refer to corresponding Philips I2C bus specification. This device is an I2C bus slave, compatible with fast (400kHz) I2C bus protocol, with write mode slave address of 8C (read mode slave address 8D). Integrators are employed at the SCL (Serial

show in real time the presence or absence of the corresponding sync. signal. They are latched to 1 as soon as a single sync. pulse is detected. In order to reset them to 0 (all at once), a 1 must be written into SDetReset I2C bus bit, the reset action taking effect with ACK bit of the I2C bus transfer to the register containing the SDetReset bit. The detection circuits are then ready to capture another event (pulse). See Note 52.

9.2.3 - MCU controlled sync. selection mode I2C bus bit VSyncAuto is set to 0. The MCU reads the polarity and signal presence detection flags, after setting the SDetReset bit to 1 and an appropriate delay, to obtain a true information of the signals applied, reads and evaluates this information and controls the vertical signal selector accordingly. The MCU has no access to polarity inverters, they are controlled automatically. See also chapter I2C BUS CONTROL REGISTER MAP on page 22. 9.2.4 - Automatic sync. selection mode I2C bus bit VSyncAuto is set to 1. In this mode, the device itself controls the I2C bus bits switching the polarity inverters (HVPol, VPol) and the vertical sync. signal selector (VSyncSel), using the information provided by detection circuitry. If both extracted and pure vertical sync. signals are present, the one already selected is maintained. No intervention of the MCU is necessary.
9.3 - HORIZONTAL SECTION
9.3.1 - General The horizontal section consists of two PLLs with various adjustments and corrections, working on horizontal deflection frequency, then phase shift-
ing and output driving circuitry providing H-drive signal on HOut pin. Input signal to the horizontal section is output of the polarity inverter on H/ HVSyn input. The device ensures automatically that this polarity be always positive. 9.3.2 - PLL1 The PLL1 block diagram is in Figure 5. It consists of a voltage-controlled oscillator (VCO), a shaper with adjustable threshold, a charge pump with inhibition circuit, a frequency and phase comparator and timing circuitry. The goal of the PLL1 is to make the VCO ramp signal match in frequency the sync. signal and to lock this ramp in phase to the sync. signal, with a possibility to adjust a permanent phase offset. On the screen, this offset results in the change of horizontal position of the picture. The loop, by tuning the VCO accordingly, gets and maintains in coincidence the rising edge of input sync. signal with signal REF1, which is derived from the VCO ramp by a comparator with threshold adjustable through HPOS I2C bus control. The coincidence is identified and flagged by lock detection circuit on pin HLckVBk as well as by HLock I2C bus flag. The charge pump provides positive and negative currents charging the external loop filter on HPosF pin. The loop is independent of the trailing edge of sync. signal and only locks to its leading edge. By design, the PLL1 does not suffer from any dead

band even while locked. The speed of the PLL1 depends on the current value provided by the charge pump. While not locked, the current is very low, to slow down the changes of VCO frequency and thus protect the external power components at sync. signal change. In locked state, the currents are much higher, two different values being selectable via PLL1Pump I2C bus bit to provide a mean to control the PLL1 speed by S/W. Lower values make the PLL1 slower, but more stable. Higher values make it faster and less stable. In general, the PLL1 speed should be higher for high deflection frequencies. The response speed and stability (jitter level) depends on the choice of external components making up the loop filter. A "CRC" filter is generally used (see Figure 4 on page 28).

The PLL1 is internally inhibited during extracted vertical sync. pulse (if any) to avoid taking into account missing or wrong pulses on the phase comparator. Inhibition is obtained by forcing the charge pump output to high impedance state. The inhibition mechanism can be disabled through PLL1Pump I2C bus bit. The Figure 7, in its upper part, shows the position of the VCO ramp signal in relation to input sync. pulse for three different positions of adjustment of horizontal position control HPOS.

9.3.3 - Voltage controlled oscillator The VCO makes part of both PLL1 and PLL2 loops, being an "output" to PLL1 and "input" to PLL2. It delivers a linear sawtooth. Figure 6 explains its principle of operation. The linears are obtained by charging and discharging an external capacitor on pin CO, with currents proportional to the current forced through an external resistor on pin RO, which itself depends on the input tuning voltage VHO (filtered charge pump output). The rising and falling linears are limited by VHOThrLo and VHOThrHi thresholds filtered through HOscF pin. At no signal condition, the VHO tuning voltage is clamped to its minimum (see chapter ELECTRICAL PARAMETERS AND OPERATING CONDITIONS, part horizontal section), which corresponds to the free-running VCO frequency fHO(0). Refer to Note 1 for the formula to calculate this frequency using external components values. The ratio between the frequency corresponding to maximum VHO and the one corresponding to minimum VHO (free-running frequency) is about 4.5. This range can easily be increased in the application. The PLL1 can only lock to input frequencies falling inside these two limits. 9.3.4 - PLL2 The goal of the PLL2 is, by means of phasing the signal driving the power deflection transistor, to lock the middle of the horizontal flyback to a certain threshold of the VCO sawtooth. This internal threshold is affected by geometry phase corrections, like e.g., parallelogram. The PLL2 is much faster than PLL1 to be able to follow the dynamism of this phase modulation. The PLL2 control current (see Figure 7) is significantly increased during discharge of vertical oscillator (during vertical retrace period) to be able to make up for the difference of dynamic phase at the bottom and at the top of the picture. The PLL2 control current is integrated on
the external filter on pin HPLL2C to obtain smoothed voltage, used, in comparison with VCO ramp, as a threshold for H-drive rising edge generation. As both leading and trailing edges of the H-drive signal in the Figure 7 must fall inside the rising part of the VCO ramp, an optimum middle position of the threshold has been found to provide enough margin for horizontal output transistor storage time as well as for the trailing edge of H-drive signal with maximum duty cycle. Yet, the constraints thereof must be taken into account while considering the application frequency range and H-flyback duration. The Figure 7 also shows regions for rising and falling edges of the H-drive signal on HOut pin. As it is forced high during the H-flyback pulse and low during the VCO discharge period, no edge during these two events takes effect. The flyback input configuration is in Figure 8. 9.3.5 - Dynamic PLL2 phase control The dynamic phase control of PLL2 is used to compensate for picture asymmetry versus vertical axis across the middle of the picture. It is done by modulating the phase of the horizontal deflection with respect to the incoming video (synchronization). Inside the device, the threshold VS(0) is compared with the VCO ramp, the PLL2 locking the middle of H-flyback to the moment of their match. The dynamic phase is obtained by modulation of the threshold by correction waveforms. Refer to Figure 12 and to chapter TYPICAL OUTPUT WAVEFORMS. The correction waveforms have no effect in vertical middle of the screen (for middle vertical position). As they are summed, their effect on the phase tends to reach maximum span at top and bottom of the picture. As all the components of the resulting correction waveform (linear for parallelogram correction and parabola of 2nd order for Pin cushion asymmetry correction) are

generated from the output vertical deflection drive waveform, they both track with real vertical amplitude and position (including breathing compensation), thus being fixed on the screen.

Non-conductive state of HOT (Horizontal Output Transistor) must correspond to non-conductive state of the device output transistor. 9.3.7 - Soft-start and soft-stop on H-drive The soft-start and soft-stop procedure is carried out at each switch-on or switch-off of the H-drive signal, either via HBOutEn I2C bus bit or after reset of XRayAlarm I2C bus flag, to protect external power components. By its second function, the external capacitor on pin HPosF is used to time out this procedure, during which the duty cycle of Hdrive signal starts at its maximum ("tHoff/TH for soft start/stop" in electrical specifications) and slowly decreases to the value determined by the control I2C bus register HDUTY (vice versa at soft-stop). This is controlled by voltage on pin HPosF. See Figure 10 and sub chapter Safety functions on page 38. 9.3.8 - Horizontal moire cancellation The horizontal moire canceller is intended to blur a potential beat between the horizontal video pixel period and the CRT pixel width, which causes visible moire patterns in the picture. It introduces a microscopic indent on horizontal scan lines by injecting little controlled phase shifts to output circuitry of the horizontal section. Their amplitude is adjustable through HMOIRE I2C bus control. The behaviour of horizontal moire is to be optimised for different deflection design configurations using HMoire I2C bus bit. This bit is to be kept at 0 for common architecture (B+ and EHT common

The duty cycle of the H-drive signal is controlled via I2C bus register HDUTY. This is overruled during soft-start and soft-stop procedures (see sub chapter Soft-start and soft-stop on H-drive on page 30 and Figure 10). The PLL2 is followed by a rapid phase shifting which accepts the signal from H-moire canceller (see sub chapter Horizontal moire cancellation on page 30) The output stage consists of a NPN bipolar transistor, the collector of which is routed to HOut pin (see Figure 9).

9.4 - VERTICAL SECTION
9.4.1 - General The goal of the vertical section is to drive vertical deflection output stage. It delivers a sawtooth waveform with an amplitude independent of deflection frequency, on which vertical geometry corrections of C- and S-type are superimposed (see chapter TYPICAL OUTPUT WAVEFORMS). Block diagram is in Figure 11. The sawtooth is obtained by charging an external capacitor on pin VCap with controlled current and by discharging it via transistor Q1. This is controlled by the CONTROLLER. The charging starts when the voltage across the capacitor drops below VVOB threshold. The discharging starts either when it exceeds VVOT threshold or a short time after arrival of synchronization pulse. This time is necessary for the AGC loop to sample the voltage at the top of the sawtooth. The VVOB reference is routed out onto VOscF pin in order to allow for further filtration. The charging current influences amplitude and shape of the sawtooth. Just before the discharge, the voltage across the capacitor on pin VCap is sampled and stored on a storage capacitor connected on pin VAGCCap. During the following ver-
tical period, this voltage is compared to internal reference REF (VVOT), the result thereof controlling the gain of the transconductance amplifier providing the charging current. Speed of this AGC loop depends on the storage capacitance on pin VAGCCap. The VLock I2C bus flag is set to 1 when the loop is stabilized, i.e. when the voltage on pin VAGCCap matches VVOT value. On the screen, this corresponds to stabilized vertical size of picture. After a change of frequency on the sync. input, the stabilization time depends on the frequency difference and on the capacitor value. The lower its value, the shorter the stabilization time, but on the other hand, the lower the loop stability. A practical compromise is a capacitance of 470nF. The leakage current of this capacitor results in difference in amplitude between low and high frequencies. The higher its parallel resistance RL(VAGCCap), the lower this difference. When the synchronization pulse is not present, the charging current is fixed. As a consequence, the free-running frequency fVO(0) only depends on the value of the capacitor on pin VCap. It can be roughly calculated using the following formula fVO(0) = 150nF C(VCap) . 100Hz
31/50
TDA9113
The frequency range in which the AGC loop can regulate the amplitude also depends on this capacitor. The C- and S-corrections of shape serve to compensate for the vertical deflection system non-linearity. They are controlled via CCOR and SCOR I2C bus controls. Shape-corrected sawtooth with regulated amplitude is lead to amplitude control stage. The discharge exponential is replaced by VVOB level, which, under control of the CONTROLLER, creates a rapid falling edge and a flat part before beginning of new ramp. Mean value of the waveform output on pin VOut is adjusted by means of VPOS I2C bus control, its amplitude through VSIZE I2C bus control. Vertical moire is superimposed. Figure 11. Vertical section block diagram
The biasing voltage for external DC-coupled vertical power amplifier is to be derived from V RefO voltage provided on pin RefOut, using a resistor divider, this to ensure the same temperature drift of mean (DC) levels on both differential inputs and to compensate for spread of VRefO value (and so mean output value) between particular devices. 9.4.2 - Vertical moire To blur the interaction of deflection lines with CRT mask grid pitch that can generate moire pattern, the picture position is to be alternated at half-frame frequency. For this purpose, a square waveform at half-frame frequency is superimposed on the output waveform's DC value. Its amplitude is adjustable through VMOIRE I2C bus control,.

9.5 - EW DRIVE SECTION
The goal of the EW drive section is to provide, on pin EWOut, a waveform which, used by an external DC-coupled power stage, serves to compensate for those geometry errors of the picture that are symmetric versus vertical axis across the middle of the picture.
The waveform consists of an adjustable DC value, corresponding to horizontal size, a parabola of 2nd order for "pin cushion" correction, a linear for "keystone" correction and independent half-parabolas of 4th order for top and bottom corner corrections. All of them are adjustable via I2C bus, see I2C BUS CONTROL REGISTER MAP on page 22 chapter.
32/50
TDA9113
Refer to Figure 12, Figure 13 and to chapter TYPICAL OUTPUT WAVEFORMS. The correction waveforms have no effect in the vertical middle of the screen (if the VPOS control is adjusted to its medium value). As they are summed, the resulting waveform tends to reach its maximum span at top and bottom of the picture. The voltage at the EWOut is top and bottom limited (see parameter VEW). According to Figure 13, especially the bottom limitation seems to be critical for maximum horizontal size (minimum DC). Actually it is not critical since the parabola component must always be applied. As all the components of the resulting correction waveform are generated from the output vertical deflection drive waveform, they all track with real vertical amplitude and position (including breathing compensation), thus being fixed vertically on the screen. They are also affected by C- and S-corrections. The sum of components other than DC is affected by value in HSIZE I2C bus
control in reversed sense. Refer to electrical specifications for value. The DC value, adjusted via HSIZE control, is also affected by voltage on HEHTIn input, thus providing a horizontal breathing compensation (see electrical specifications for value). The resulting waveform is conditionally multiplied with voltage on HPLL1F, which depends on frequency. Refer to electrical specifications for value and more precision. This tracking with frequency provides a rough compensation of variation of picture geometry with frequency and allows to fix the adjustment ranges of I2C bus controls throughout the operating range of horizontal frequencies. It can be switched off by EWTrHFr I2C bus bit (off by default). The EW waveform signal is buffered by an NPN emitter follower, the emitter of which is directly routed to EWOut output, with no internal resistor to ground. It is to be biased externally.

9.6 - DYNAMIC CORRECTION OUTPUTS SECTION
9.6.1 - Horizontal dynamic correction output HDyCor A parabolic waveform at horizontal frequency is output on pin HDyCor. It can be adjusted in amplitude and phase (HDC-AMP and HDC-SYM I2C bus controls). See also I2C BUS CONTROL REGISTER MAP on page 22. The minimum value in horizontal parabola amplitude I2C bus control does not correspond to null horizontal amplitude. Refer to Figure 14. The phase of the parabola can roughly be adjusted via HDyCorPh I2C bus bit to coincide either with the beginning or the middle of the H-flyback pulse. Moreover, its centre can be offset via HDC-SYM I2C bus control. There is a flat part of a quasi-constant length at the beginning of
the parabola. Refer to electrical specifications for values. The parabola tracks with value in HSIZE control and is horizontal breathing compensated if HDyCorTr I2C bit is set to 1 (0 by default). 9.6.2 - Vertical dynamic correction output VDyCor A parabola at vertical deflection frequency is available on pin VDyCor. Its amplitude is adjustable via VDC-AMP I2C bus control and polarity controlled via VDyCorPol I2C bus bit. It tracks with real vertical amplitude and position (including breathing compensation). It is also affected by C- and S-corrections. The use of both correction waveforms is up to the application (e.g. dynamic focus).

9.7 - DC/DC CONTROLLER SECTION
The section is designed to control a switch-mode DC/DC converter. A switch-mode DC/DC convertor generates a DC voltage from a DC voltage of different value (higher or lower) with little power losses. The DC/DC controller is synchronized to horizontal deflection frequency to minimize potential interference into the picture. Its operation is similar to that of standard UC3842. The schematic diagram of the DC/DC controller is in Figure 15. The BOut output controls an external switching circuit (a MOS transistor) delivering pulses synchronized on horizontal deflection frequency, the phase of which depends on I2C bus configuration, see the table at the end of this chapter. Their duration depends on feedback provided to the circuit, generally a copy of DC/DC converter output voltage and a copy of current passing through the DC/DC converter circuitry (e.g. current through external power component). The polarity of the output can be controlled by BOutPol I2C bus
bit. A NPN transistor open-collector is routed out to the BOut pin. During the operation, a sawtooth is to be found on pin BISense, generated externally by the application. According to BOutPh I2C bus bit, the R-S flipflop is set either at H-drive signal edge (rising or falling, depending on BOHEdge I2C bus bit), or a certain delay (tBTrigDel / TH) after middle of H-flyback. The output is set On at the end of a short pulse generated by the monostable trigger. Timing of reset of the R-S flip-flop affects duty cycle of the output square signal and so the energy transferred from DC/DC converter input to its output. A reset edge is provided by comparator C2 if the voltage on pin BISense exceeds the internal threshold VThrBIsCurr. This represents current limitation if a voltage proportional to the current through the power component or deflection stage is available on pin BISense. This threshold is affected by the voltage on pin HPosF, which rises at soft start and descends at soft stop. This ensures self-contained soft control of duty cycle of the output signal on pin BOut. Refer to Figure 10. Another

condition for the reset of the R-S flip-flop, OR-ed with the one described before, is that the voltage on pin BISense exceeds the voltage VC1, which depends on the voltage applied on input BISense of the error amplifier O1. The two voltages are compared, and the reset signal generated by the comparator C1. The error amplifier amplifies (with a factor defined by external components) the difference between the input voltage proportional to DC/DC convertor output voltage and internal reference VBReg. The internal reference and so the output voltage is I2C bus adjustable by means of BREF I2C bus control.
Both step-up (DC/DC converter output voltage higher than its input voltage) and step-down (output voltage lower than input) are possible. DC/DC controller Off-to-On edge timing

9.8 - MISCELLANEOUS
9.8.1 - Safety functions The safety functions comprise supply voltage monitoring with appropriate actions, soft start and soft stop features on H-drive and B-drive signals on HOut and BOut outputs and X-ray protection. For supply voltage supervision, refer to paragraph Power supply and voltage references on page 26 and Figure 1. A schematic diagram putting together all safety functions and composite PLL1 lock and V-blanking indication is in Figure 16. 9.8.2 - Soft start and soft stop functions For soft start and soft stop features for H-drive and B-drive signal, refer to paragraph Soft-start and soft-stop on H-drive on page 30 and sub chapterDC/DC CONTROLLER SECTION on page 36, respectively. See also the Figure 10. Regardless why the H-drive or B-drive signal are switched on or off (I2C bus command, power up or down, X-ray protection), the signals always phase-in and phase-out in the way drawn in the figure, the first
to phase-in and last to phase-out being the H-drive signal, which is to better protect the power stages at abrupt changes like switch-on and off. The timing of phase-in and phase-out only depends on the capacitance connected to HPosF pin which is virtually unlimited for this function. Yet it has a dual function (see paragraph PLL1 on page 27), so a compromise thereof is to be found. 9.8.3 - X-ray protection The X-ray protection is activated if the voltage level on XRay input exceeds VThrXRay threshold. As a consequence, the H-drive and B-drive signals on HOut and BOut outputs are inhibited (switched off) after a 2-horizontal deflection line delay provided to avoid erratic excessive X-ray condition detection at short parasitic spikes. The XRayAlarm I2C bus flag is set to 1 to inform the MCU. This protection is latched; it may be reset either by VCC drop or by I2C bus bit XRayReset (see chapter I2C BUS CONTROL REGISTER MAP on page 22).

9.8.4 - Composite output HLckVBk The composite output HLckVBk provides, at the same time, information about lock state of PLL1 and early vertical blanking pulse. As both signals have two logical levels, a four level signal is used to define the combination of the two. Schematic diagram putting together all safety functions and composite PLL1 lock and V-blanking indication is in Figure 16, the combinations, their respective levels and the HLckVBk configuration in Figure 17. The early vertical blanking pulse is obtained by a logic combination of vertical synchronization pulse and pulse corresponding to vertical oscillator discharge. The combination corresponds to the drawing in Figure 17. The blanking pulse is started with Figure 17. Levels on HLckVBk composite output
the leading edge of any of the two signals, whichever comes first. The blanking pulse is ended with the trailing edge of vertical oscillator discharge pulse. The device has no information about the vertical retrace time. Therefore, it does not cover, by the blanking pulse, the whole vertical retrace period. By means of BlankMode I2C bus bit, when at 1 (default), the blanking level (one of two according to PLL1 status) is made available on the HLckVBk permanently. The permanent blanking, irrespective of the BlankMode I2C bus bit, is also provided if the supply voltage is low (under VCCEn or VCCDis thresholds), if the X-ray protection is active or if the V-drive signal is disabled by VOutEn I2C bus bit.
