I2C-bus controlled TV display processors

FUNCTIONAL DESCRIPTION RGB control circuit

INPUT SIGNALS The RGB control circuit of the TDA933xH contains three

sets of input signals:

• YUV input signals, which are supplied by the input processor or the feature box. Bit GAI can be used to switch the luminance input signal sensitivity between

0.45 V (p-p) and 1.0 V (b-w). The nominal input signals for U and V are 1.33 V (p-p) and 1.05 V (p-p), respectively. These input signals are controlled on contrast, saturation and brightness.

• The first RGB input is intended for external signals (SCARTin 1fHandVGA in 2fHapplications),which have an amplitude of 0.7 V (p-p) typical. This input is also controlled on contrast, saturation and brightness.

• The second RGB input is intended for OSD and teletext signals. The required input signals havean amplitude of

0.7 V (p-p). The switching between the internal signal and the OSD signal can be realized via a blending function or via fast blanking. This input is only controlled on brightness.

Switchingbetween the various sources canberealized via the I2C-bus and by fast insertion switches. The fast insertion switches can be enabled via the I2C-bus.

The circuit contains switchable matrix circuits for the colour difference signals so that the colour reproduction can be adapted for PAL/SECAM and NTSC. For NTSC, two different matrices can be chosen. In addition, a matrix for high-definition ATSC signals is available.

OUTPUT AMPLIFIER The output signal has an amplitude of approximately

2 V (b-w) at nominal input signals and nominal settings of the controls. The required ‘white point setting’ of the picture tube can be realized by means of three separate gain settings for the RGB channels.

To obtain an accurate biasing of the picture tube, a CCC circuit has been developed. This function is realized by a 2-point black level stabilization circuit.

Byinsertingtwotestlevelsforeachgunandcomparing the resulting cathode currents with two different reference currents,the influence of thepicture tube parameters such as the spread in cut-off voltage can be eliminated.

TDA933xH series

This 2-point stabilization is based on the principle that the ratio between the cathode currents is coupled to the ratio

k1 k2

dr1



-----------



dr1

between the drive voltages according to:

------ I

The feedback loop makes the ratio between cathode currents I

and Ik2 equal to the ratio between the

reference currents (which are internally fixed)by changing the (black) level and the amplitude of the RGB output signals via two converging loops. The system operates in such a way that the black level of the drive signal is controlled to thecut-off point of the gun. In this way, a very good grey scale tracking is obtained. The accuracy of the adjustmentof the black level isonly dependent on the ratio ofinternalcurrents and these can be madeveryaccurately in integrated circuits. An additional advantage of the 2-point measurement is that the control system makes the absolute value of Ik1 and Ik2 identical to the internal reference currents. Because this adjustment is obtained by adapting the gain of the RGB control stage, this control stabilizes the gain of the complete channel (RGB output stage and cathode characteristic). As a result, this 2-point loop compensates for variations in the gain figures during life.

An important property ofthe 2-point stabilizationis that the offset and the gain of the RGB path are adjusted by the feedback loop. Hence, the maximum drive voltage for the cathode is fixed by the relationship between the test pulses, the reference current and the relative gain setting of the three channels. Consequently, the drive level of the CRT cannot be adjusted by adapting the gain of the RGB output stage. Because different picture tubes may require different drive levels, the typical ‘cathode drive level’ amplitudecan be adjusted bymeans of an I2C-bussetting. Depending on the selected cathode drive level, the typical gain of the RGB output stages can be fixed, taking into account the drive capability of the RGB outputs (pins 40 to 42). More details about the design are given in the application report (see also Chapter “Characteristics”; note 11).

The measurement of the high and the low currents of the 2-point stabilization circuit isperformed in two consecutive fields. The leakage current is measured in each field. The maximum allowable leakage current is 100 µA.

For extra flexibility, it also possible to switch the CCC circuit to 1-point stabilization with the OPC bit. In this mode, only the blacklevel at theRGB outputs is controlled by the loop. The cathode drive level setting has no influence on the gain in thismode. This level should be set to the nominal value to get the correct amplitude of the measuring pulses.

I2C-bus controlled TV display processors

Via the I2C-bus, an adjustable offset can be made on the black level of red and green channels with respect to the level that is generated by the black current control loop. These controls can be used to adjust the colour temperature of the dark part of the picture, independent of the white point adjustment.

When the TV receiver is switched on, the black current stabilization circuit is directly activated and the RGB outputs are blanked. The blanking is switched off as soon as the loop has stabilized (e.g. the first time that bit BCF changes from 1 to 0, see also Chapter “Characteristics”; note 15). This ensures that the switch-on time is reduced to a minimum and is only dependent on the warm-up time of the picture tube.

The black current stabilization system checks the output levelof the three channels andindicateswhether the black level of the lowest RGB output of the IC is in a certain window (WBC bit), below or above this window (HBC bit). This indication can be read from the I2C-bus and can be used for automatic adjustment of voltage Vg2 during the production of the TV receiver.

TDA933xH series

Synchronization and deﬂection processing

HORIZONTAL SYNCHRONIZATION AND DRIVE CIRCUIT The horizontal drive signal is obtained from an internal

VCO which runs at a frequency of 440 times (2fHmode) or 880 times (1fHmode) the frequency of the incoming H signal. The free-running frequency of this VCO is calibrated by a crystal oscillator which needs an external 12 MHz crystal or ceramic resonator as a reference. It is also possible to supply an external reference signal to the IC (in this case, the external resonator should be removed).

The VCO is synchronized to the incoming horizontal H pulse (applied from the feature box or the input processor) by a PLL with an internal time constant. The frequency of thehorizontaldrive signal (1fHor2fH)isselected by means of a switching pin, which must be connected to ground or left open circuit.

For HDTV applications, it is possible to change the free-running frequency of the horizontal drive output from

31.2 kHz to 33.7 kHz by means of bit HDTV.

When a failure occurs in theblack current loop (e.g. due to an open circuit), statusbit BCF is set.This information can be used to blank the picture tube to avoid damage to the screen.

The control circuit contains an average beam current limiting circuit and a peak white level (PWL) circuit. The PWL detects small white areas in the picture that are not detected by the average beam current limiter. The PWL can be adjusted via the I2C-bus. A low-pass filter is placed in front of the peak detector to prevent it from reacting to short transients in the video signal. The capacitor of the low-pass filter is connected externally so that the set maker can adapt the time constant as required. The IC also contains a soft clipper that limits the amplitude of the shorttransientsintheRGBoutputsignals.Inthisway,spot blooming on, for instance, subtitles is prevented. The differencebetween the PWL and thesoftclipping level can be adjusted via the I2C-bus in a few steps.

The vertical blanking is adapted to the vertical frequency of the incoming signal (50 or 100 Hz or, 60 or 120 Hz). When the flyback time of the vertical output stage is greater than the 60 Hz blanking time, the blanking can be increased to the same value as that of the 50 Hz blanking. This can be set by means of bit LBM.

When no video is available, it is possible to insert a blue background. This feature can be activated via bit EBB.

For safety reasons, switching between 1fH and 2f modes is only possible when the IC is in the standby mode.

For the TDA9331H and TDA9332H, it is also possible to set the horizontal PLL to a ‘multi-sync’ mode by means of bit VGA. In this mode, the circuit detects the frequency of theincomingsyncpulses and adjusts the centre frequency of the VCO accordingly by means of an internal Digital-to-Analog-Converter (DAC). The frequency range in this mode is 30 to 50 kHz at the output.

The polarities of the incoming HD and VD pulses are detected internally. The detected polarity can be read out via status bits HPOL and VPOL.

The horizontal drive signal is generated by a second control loop which compares the phase of the reference signal (applied from the internal VCO) with the flyback pulse. The time constant of this loop is set internally. The IC has a dynamic horizontal phase correction input, which can be used to compensate phase shifts that are caused by beam current variations. Additional settings of the horizontal deflection (which are realized via the second loop) are the horizontal shift and horizontal parallelogram and bow corrections (see Chapter “Characteristics”; Fig.16). The adjustments are realized via the I2C-bus.

When no horizontal flyback pulse is detected during three consecutive line periods, status bit NHF is set (output status byte 01-D3; see Table 3).

I2C-bus controlled TV display processors

The horizontal drive signal is switched on and off via the so-called slow-start/slow-stop procedure. This function is realizedby varying the tonof the horizontal drive pulse. For EHT generators without a bleeder, the IC can be set to a ‘fixed beam current mode’ via bit FBC. In this case, the picture tube capacitance is discharged with a current of approximately 1 mA. The magnitude of the discharge current is controlled via the black current feedback loop. If necessary, the discharge current can be enlarged with the aid of an external currentdivision circuit. With the fixed beam current option activated, it is still possible to have a black screen during switch-off. This can be realized by placing the vertical deflectionin an overscan position. This mode is activated via bit OSO.

An additional mode of the IC is the ‘low-power start-up’ mode.This mode is activated when asupplyvoltageof 5 V is supplied to the start-up pin.

The required current for this mode is 3 mA (typ.). In this condition, the horizontal drive signal has the nominal t and the ton grows gradually from zero to approximately 30% of the nominal value. This results in a line frequency of approximately 50 kHz (2fH) or 25 kHz (1fH). The output signal remains unchanged until the main supply voltage is switched on and the I2C-bus data has been received. The horizontal drive then gradually changes to the nominal frequency and duty cycle via the slow-start procedure.

TheICcanonlybeswitched on and to standby mode when both standby bits (STB0 and STB1) are changed. The circuit will not react when only one bit changes polarity.

The IC has a general purpose bus controlled DAC output with a 6-bit resolution and with an output voltage range between 0.2 to 4 V. In the TDA9331H, the DC voltage on this output is proportional to the horizontal line frequency (only in VGA mode). This voltage can be used to control the supply voltage of the horizontal deflection stage, to maintain constant picture width for higher line frequencies.

VERTICAL DEFLECTION AND GEOMETRY CONTROL The drive signals for the vertical and E-W deflection

circuits are generated by a vertical divider, which derives its clock signal from the line oscillator. The divider is synchronized by the incoming VDpulse, generated by the input processor or the feature box. The vertical ramp generator requires an external resistor and capacitor; the tolerances for these components must be small. In the normal mode, the vertical deflection operates in constant slope and adapts its amplitude, depending on the frequency of the incoming signal (50 or 60 Hz, or 100 or 120 Hz). When the TDA933xH is switched to the VGA mode, the amplitude of the vertical scan is stabilized

off

TDA933xH series

andindependent of the incomingvertical frequency. In this mode, the E-W drive amplitude is proportional to the horizontalfrequency so that the correctiononthe screen is not affected.

The vertical drive is realized by a differential output current. The outputs must be DC-coupled to the vertical output stage (e.g. TDA8354).

The vertical geometry can be adjusted via the I2C-bus. Controls are possible for the following parameters:

• Vertical amplitude

• S-correction

• Vertical slope

• Vertical shift (only for compensation of offsets in output

stage or picture tube)

• Vertical zoom

• Verticalscroll (shifting the picture inthevertical direction

when the vertical scan is expanded)

• Vertical wait, an adjustable delay for the start of the vertical scan.

Withregardtothevertical wait, the following conditions are valid:

• In the 1fHTV mode, the start of the vertical scan is fixed and cannot be adjusted with the vertical wait

• In the 2fH TV mode, the start of the vertical scan depends on the value of the Vertical Scan Reference (VSR) bus bit. If VSR = 0, the start of the vertical scan is related to the end of the incoming VDpulse. If VSR = 1, it is related to the start. In both cases, the start of the scan can be adjusted with the vertical wait setting

• In the multi-sync mode (TDA9331H and TDA9332H both in 1fHmode and 2fHmode), the start of the vertical scan is related to the start of the incoming VDpulse and can be adjusted with the vertical wait setting.

The minimum value for the vertical wait setting is 8 line periods. If the setting is lower than 8, the wait period will remain at 8 line periods.

The E-W drive circuit has a single-ended output. The E-W geometry can be adjusted on the following parameters:

• Horizontal width with increased range because of the ‘zoom’ feature

• E-W parabola/width ratio

• E-W upper corner/parabola ratio

• E-W lower corner/parabola ratio

• E-W trapezium.

I2C-bus controlled TV display processors

The IC has an EHT compensation input which controls both the vertical and the E-W output signals. The relative control effect on both outputs can be adjusted via the I2C-bus (sensitivity of vertical correction is fixed; E-W correction variable).

Toavoiddamagetothe picture tube in the event of missing or malfunctioning vertical deflection, a vertical guard function is available at the sandcastle pin (pin SCO). The vertical guard pulse from the vertical output stage (TDA835x) should be connected to the sandcastle pin, which acts as a current sense input. If the guard pulse is missing or lasts too long, bit NDF is set in the status register and the RGB outputs are blanked. If the guard function is disabled via bit EVG, only NDF status bit NHF is set.

TheICalsohasinputsforflashandovervoltageprotection. More details about these functions are given in Chapter “Characteristics”; note 43.

Notes

1. The normal operation of the IC is guaranteed for a supply voltage between 7.2 and 8.8 V. When the supply voltage drops below the POR level, status bit POR is set and the horizontal output is switched off. When the supply voltage is between 7.2 V and the POR level, the horizontal frequency is kept in the specified holding range.

2. For the low power start-up mode, a voltage of 5 V has to be supplied to pin 22. The current that is required for this function is about 3.0 mA. After the start-up voltage is applied, the signal at the horizontal drive output will have nominal t

, while ton grows gradually from zero to about 30% of the nominal value, resulting in a line frequency of

off

approximately 50 kHz (2fH) or 25 kHz (1fH). The start-up mode is continued as soon as the main supply voltage is switched on and the I2C-bus data has been received. After status bit POR has been read out, bits STB must be set to 1 within 24 ms, to continue slow start. If bits STB are not sent within 24 ms, the horizontal output will be automatically switched off via slow stop. It is also possible to first set bits STB to 1, before reading bit POR. Start-up of the horizontal output will then continue 24 ms after bit POR is read. When the main supply is present, the 5 V supply on pin 22 can be removed. If low power start-up is not used, pin 22 should be connected to ground. More information can be found in the application report.

3. The RGB to YUV matrix on the RGB-1 input is the inverse of the YUV to RGB matrix for PAL. For a one-on-one transfer of all three channels from the RGB-1 input to the RGB output, the PAL colour difference matrix should be selected (MAT = 0, MUS = 0).

4. The colorimetry that is used for high definition ATSC signals is described in document ANSI/SMPTE 274M-1995. The formula to compute the luminance signalfrom the RGBprimary components differsfrom the formulathat is used for the PAL system. The consequence is that a different matrix is needed to calculate the internal G − Y signal from the R − Y and B − Y signals, see the formulas below:

The G − Y signal can be derived from the formula for Y:

5. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix batches which are made in the pilot production period.

6. The inputs for RGB-1 and RGB-2 insertion (pins 33 and 38) both supply a small source currentto the pins. If the pins are left open circuit, the input voltage will rise above the insertion switching level.

7. This parameter is measured at nominal settings of the various controls.

8. The switching of the OSD (RGB-2) input has two modes, which can be selected via the I

C-bus: a) Fast switching between the OSD signal and the internal RGB signals. b) Blending (fading) function between the OSD signal and the internal RGB signals. The blending control curve is

given in Fig.4. The blender input is optimized for the blender output of the SAA5800 (ArtistIC).

9. The saturation, contrast and brightness controls are active on the YUV signals and on the first RGB input signals. Nominal contrast is specified with the contrast DAC in position 32 DEC, nominal saturation with the saturation DAC in position 22 DEC. The second RGB input (which is intended to be used for OSD and teletext display) can only be controlled on brightness.

10. For video signals with a black level that deviates from the back-porch blanking level, the signal is ‘stretched’ to the blanking level. The amount of correction depends on the IRE value of the signal (see Fig.8). The black level is detected by means of an internal capacitor. The black level stretcher can be switched on and off via bit BKS in the I2C-bus. The values given in the specification are valid only when the luminance input signal has an amplitude of 1 V (b-w).

11. Because of the 2-point black current stabilization circuit, both the black level and the amplitude of the RGB output signals depend on the drive characteristic of the picture tube. The system checks whether the returning measuring currents meet the requirement and adapts the output level and gain ofthe circuit asnecessary. Therefore, the typical values of the black level and amplitude at the output are just given as an indication for the design of the RGB output stage.

a) The 2-point black level system adapts the drive voltage for each cathode such that the two measuring currents

have the right value. The consequence is that a change in the gain of the output stage will be compensated by a gain change of the RGB control circuit. Because different picture tubes may require different drive voltage amplitudes, the ratio between the output signal amplitude and the inserted measuring pulses can be adapted via the I2C-bus. This is indicated in the parameter ‘Adjustment range of RGB drive levels’.

b) Because of the dependence of the output signal amplitude on the application, the peak-white and soft-clipping

limiting levels have been related to the input signal amplitude.

c) The signal amplitude at the RGB outputs of the TDA933xH depends on the gain of the RGB amplifiers. The gain

of the RGB amplifiers should be 35 to get the nominal signal amplitude of 2 V (b-w) at the RGB outputs for a cathode drive level of 70 V (b-w) and the nominal setting of the drive level bits (CL

12. The bandwidth of the video channels depends on the capacitive load at the RGB outputs. For 2fH or VGA applications, external (PNP) emitter followers on the RGB outputs of the TDA933xH are required, to avoid reduction of the bandwidth by the capacitance of the wiring between the TDA933xH and the RGB power amplifiers on the picture tube panel. If emitter followers are used, it should be possible to obtain the bandwidth figures that are mentioned for 10 pF load capacitance.

13. The timing of the horizontal blanking pulse on the RGB outputs is illustrated in Fig.10. a) The start of the blanking pulse is determined by an internal counter blanking that starts 40 LLC (line locked clock)

pulses before the centre of the horizontal flyback pulse. This is 5.8 µs for 1fH and 2.9 µs for 2fH TV mode. The end of the blanking is determined by the trailing edge of the flyback pulse. If required, the start of the counter blanking can be adjusted in 15 steps with bus bits LBL3 to LBL0. This can be useful when HDTV or VGA signals are applied to the IC.

b) When the reproduction of 4 : 3 pictures on a 16 : 9 picture tube is realized by reducing the horizontal scan

amplitude,the edges of the picturemay be slightly disturbed. Thiseffectcan be prevented by addingan additional blanking pulse to the RGB signals. This blanking pulse is derived from the horizontal oscillator and is directly related to the incoming HD pulse (independent of the flyback pulse). The additional blanking pulse overlaps the normal blanking signal by approximately 1 µs (1fH) or 0.5 µs (2fH) on both sides. This wide blanking is activated by bit HBL. The phase of this blanking can be controlled in 15 steps by bits HB3 to HB0.

14. When a YUV or RGB signal is applied to the IC and no separate horizontal or vertical timing pulses are available, an external sync separator circuit is needed. The TDA933xH has an edge triggered phase detector circuit on the H input that uses the start of the HD pulse as timing reference. To avoid horizontal phase disturbances during the vertical blanking period, it is important that the sync separator does not generate extra horizontal sync pulses during the vertical sync pulse on the video signal.

15. Start-up behaviour of the CCCloop. After the horizontaloutput is released via bits STB,the RGB outputs areblanked and the CCC loop is activated. Because the picture tube is cold, the measured cathode currents are too small, and both gain and offset are set at the maximum value so that the CCC loop gets out of range and status bit BCF is set to 1. Once the picture tube is warm, the loop comes within range and the set signal for bit BCF is removed. Status bit BCF is set if the voltage of at least one of the cut-off measurement lines at the RGB outputs is lower than 1.5 V or higher than 3.5 V. The RGB outputs are unblanked as soon as bit BCF changes from 1 to 0. To avoid a bright picture after switch-on with a warm picture tube, reset of bit BCF is disabled for 0.5 s after switch-on of the horizontal output. If required, the blanking period of the RGB outputs can be increased by forcing the blanking level at the RGB outputs via RBL = 1. When status bit BCF changes from 1 to 0, bit RBL can be set to 0 after a certain waiting period.

16. Voltage Vg2of the picture tube can be aligned with the help of status bits WBC and HBC. Bit WBC becomes 1 if the lowest of the three RGB output voltages during the cut-off measurement lines is within the alignment window of ±0.1 V around 2.5 V. Bit HBC is 0 if the lowest cut-off level is below 2.6 V, and 1 if this level is above 2.6 V.

a) Voltage Vg2should be aligned such that bit WBC becomes 1. If bit WBC is 0, bit HBC indicates in which direction

voltage Vg2 should be adjusted. If bit HBC = 0, the DC level at the RGB outputs of the IC is too low and voltage Vg2shouldbe adjusted lower until bit WBC becomes1. If HBC = 1, the DC levelistoo high and voltage Vg2should be adjusted higher until bit WBC becomes 1.

b) It should be noted that bit WBC is onlymeant for factory alignmentof voltage Vg2. If the value of bit WBC depends

on the video content, this is not a problem. Correct operation of the black current loop is guaranteed as long as status bit BCF = 0, meaning that the DC level of the measurement lines at the RGB outputs of the IC is between

1.5 and 3.5 V.

17. Signal-to-noise ratio (S/N) is specified as a peak-to-peak signal with respect to RMS noise (bandwidth 10 MHz).

18. This is a current input.When the black current feedbackloop is closed (only duringmeasurement lines or during fixed beam current switch off), the voltage at this pin is clamped at 3.3 V. When the loop is open circuit, the input is not

clamped and the maximum sink current is approximately 100 µA. The voltage on the pin must not exceed the supply voltage.

19. The control circuit contains a PWL circuit and a soft clipper. a) The detection level of the PWL can be adjusted via the I2C-bus in a control range between 0.65 and 1.0 V (b-w).

This amplitude is related to the Y input signal, typical amplitude 1 V (b-w), at maximum contrast setting. The detector measures the amplitude of the RGB signals after the contrast control. The output signal of the PWL detector is filtered by an external capacitor, so that short transients in the video signal do not activate the limiting action. Because the capacitor is externally available at pin 34, the set maker can adapt the filter time constant as required. The contrast reduction of the PWL is obtained by discharging theexternal capacitor atthe beam current limiting input (pin 43). To avoid the PWL circuit from reducing the contrast of the main picture when the amplitude of the inserted RGB2 signal is too high, the output current of the PWL detector is disabled when the fast blanking input (pin 38) is high. In blending mode (OBL = 1), the PWL detector is disabled when the blending voltage is above the 50% insertion level. The soft clipper circuit will still limit the peak voltage at the RGB outputs.

b) In addition to the PWL circuit, the IC contains a soft clipper function which limits short transients that exceed the

PWL. The difference between the PWL and the soft clipping level can be adjusted between 0 and 10% in three steps via the I2C-bus, with bus bits SC1 and SC0 (soft clipping level equal or higher than the PWL). It is also possible to switch off the soft clipping function.

20. The above-mentioned output amplitude range at which the PWL detector is activated is valid for nominal settings of the white point controls, and when the CCC loop is switched off or set to 1-point stabilization mode. In 2-point stabilization mode, the mentioned range is only valid when the gain of the RGB output stages is dimensioned such that the RGB output amplitudes are 2 V (b-w) for nominal contrast setting, see also note 11.

21. The soft clipper gain reduction is measured by applying a sawtooth signal with rising slope and 1 V (b-w) at the luminance input. To prevent the beam current limiter fromoperating, a DCvoltage of 3.5 V must be applied to pin 43. The contrast is set at the maximum value, the PWL at the minimum value, and the soft clipping level is set at 0% above the PWL (SC10= 00). The tangents of the sawtooth waveform at one of the RGB outputs is now determined at the beginning and end of the sawtooth. The soft clipper gain reduction is defined as the ratio of the slopes of the tangents for black and white, see Fig.9.

22. When the blue stretch function is activated (via I2C-bus bit BLS), the gain of the red and green channels is reduced for input signals that exceed a value of 80% of the nominal amplitude. The result is that the white point is shifted to a higher colour temperature.

23. Switch-off behaviour of TDA933xH. For applications with an EHT generator without bleeder resistor, the picture tube capacitance can be discharged with a fixed beam current when the set is switched off. The magnitude of the dischargecurrent is controlled via theblack current loop. The fixedbeamcurrent mode can be activatedwith bit FBC. With the fixed beam current option activated, it is still possible to have a black screen during switch-off. This is realized by placing the vertical deflection in the overscan position. This mode is activated by bit OSO. There are two possible situations for switch-off (see notes 24 and 25).

24. The set is switched to standby via the I2C-bus. In this situation, the procedure is as follows: a) Vertical scan is completed. b) Vertical flyback is completed. c) Slow stop of the horizontal output is started, by gradually reducing the ‘on-time’ at the horizontal output from

nominal to zero. d) At the same moment, the fixed beam current is forced via the black current loop (if FBC = 1). e) If OSO = 1, the vertical deflection stays in overscan position; if OSO = 0, the vertical deflection keeps running. f) The slow stop time is approximately 50 ms, the fixed beam current flows for 18.6 ms or 25 ms, depending on the

value of bit TFBC, see Fig.15.

25. The set is switched off via the mains power switch. When the mains supply is switched off, the supply voltage of the line deflection circuit of the TV set will decrease. A detection circuit must be made that monitors this supply voltage.

TDA933xH series

2000 May 08 31

Page 32

Philips Semiconductors Preliminary speciﬁcation

I2C-bus controlled TV display processors

TDA933xH series

When the supply voltage suddenly decreases, pin FBCSO (fixed beam current switch-off) of the TDA933xH must be pulled high. In this situation, the procedure is as follows:

a) Vertical scan is completed. b) Vertical flyback is completed. c) The fixed beam current is forced via the black current loop (if FBC = 1). The horizontal output keeps running.

As the supply voltage for the line transformer decreases, the EHT voltage will also decrease. d) If OSO = 1, the vertical deflection stays in overscan position; if OSO = 0, the vertical deflection keeps running. e) When the supply voltage of the TDA933xH drops below the POR level, horizontal output and fixed beam current

are stopped.

26. The discharge current for the picture tube can be increased with an external current division circuit on the black current input (pin 44). The current division should only be active for high cathode currents, so that the operation of the black current stabilization loop is not affected. When the feedback current supplied to pin 44 is less than 1mA, the DC level at the RGB outputs will go to the maximum value of 6.0 V (2-point black current stabilization) or 5.6 V (1-point or no black current stabilization).

27. A stable switching of the HD input is realized by using a Schmitt trigger input.

28. The simplified circuit diagram of the oscillator is given in Fig.3. To ensure that the oscillator will start-up, the ceramic resonator must fulfil the following condition: .

Ri1.1≤× 10

19–

Example: When the resonator is loaded with 60 pF (this is a typical value for a 12 MHz resonator), the series resistance of the resonator must be smaller than 30 Ω. A suitable ceramic resonator for use with the TDA933xH is the Murata CST12.0MT, which has built-in load capacitances Ca and Cb. For higher accuracy, it is also possible to use a quartz crystal, which is even less critical with respect to start-up because of its lower load capacitance.

29. Pin HSEL must be connected to ground in a 1f

application; it must be left open circuit for a 2fH application. The

TDA9331H and TDA9332H can be switched to a multi-sync mode, in which the horizontal frequency can vary between 15 and 25 kHz (1fH mode) or 30 and 50 kHz (2fH mode).

30. The indicated tolerance on the free-running frequency is only valid when an accurate reference frequency (obtained with an accurate 12 MHz crystal) is used. The tolerance of the reference resonator must be added to obtain the real tolerance on the free-running frequency.

31. The correction factor k of the phase-2 loop is defined as the amount of correction per line period of a phase error between the horizontal flyback pulse and the internal phase-2 reference pulse. When k = 0.5, the phase error between the flyback pulse and the internal reference is halved each line period.

32. The control range of the second control loop depends on the line frequency. The maximum control range from the rising edge of HOUT to the centre of the flyback pulse is always 37% of one line period, for the centre position of the dynamic phase compensation (4.0 V at pin 14).

33. The dynamic phase compensation input (pin 14) is connected to an internal reference voltage of 4.0 V via a resistor of 100 kΩ. If dynamic phase compensation is not used, this pin should be decoupled to ground (pin 19) via a capacitor of 100 nF.

34. The range of parallelogram and bow correction is proportional to the width of the horizontal flyback pulse. For zero correction, use DAC setting 7 DEC or 0111 (bin). The effect of the corrections is shown in Fig.16.

35. For safe operation of the horizontal output transistor and to obtain a controlled switch-on time of the EHT, the horizontal drive starts up in a slow start mode. The horizontal drive starts with a very short ‘on-time’ of the horizontal outputtransistor (line locked clock pulse, i.e. 72 ns),the‘off-time’ of the transistor is identicaltothe ‘off-time’ in normal operation. The starting frequency during switch-on is therefore approximately twice the normal value. The ton is slowlyincreased to the nominal valueinapproximately 160 ms (see Fig.15). Whenthenominal frequency is reached, the PLL is closed such that only very small phase corrections are necessary. This ensures safe operation of the output stage.

a) For picture tubes with Dynamic Astigmatic Focusing (DAF) guns, the rise of the EHT voltage between

75 and 100% is preferred to be even slower than the rise time from 0 to 75%. This can be realized by activating bit ESS, at which the total switch-on time of the horizontal output pulse is approximately 1175 ms.

b) During switch-off, the slow-stop function is active. This is realized by decreasing the ton of the output transistor

complementary to the start-up behaviour. The switch-off time is approximately 50 ms. The slow-stop procedure is synchronized to the start of the first new vertical field after reception of the switch-off command. During the slow-stop period, the fixed beam current switch-off can be activated (see also note 23). This current is active during a part of the slow stop period, see Fig.15.

c) The horizontal output is gated with the flyback pulse so that the horizontal output transistor cannot be switched

on during the flyback pulse. This protection is not active during the switch-on or switch-off period.

36. This parameter is not tested during production and is just given as application information for the designer of the television receiver.

37. The rise and fall times of the blanking pulse and clamping pulse at the sandcastle output (pin 9) depend on the capacitive load. The value of the source current during the rising edge or sink current during the falling edge is

0.7 mA (typical value).

38. The vertical guard pulse from the vertical output stage should fall within the vertical blanking period (see Figs 12 and 13) and should have awidth of at least oneline period. For the detectionof a missing pulse, aguard currentvalue of 1 mA during normaloperationis sufficient. If the RGBoutputsmust also be blanked ifthe guard pulse lasts longer than the vertical blanking period, the guard current must have a value between 2.6 mA and 3.5 mA.

39. Switching between the 1fV or the 2fV mode is realized via bit SVF.

40. The vertical linearity is measured on the differential output current at the vertical drive output (pins 1 and 2) for zero S-correction. The linearity is defined as the ratio of the upper and lower half amplitudes at the vertical output. The upper amplitude is measured between lines 27 and 167, the lower amplitude between lines 167 and 307 for a 50 Hz video signal.

41. The field detection mechanism is explained in Fig.17. a) The incoming VD pulse is synchronized with the internal clock signal CK2H that is locked to the incoming H

pulse. If the synchronized VD pulse of a field coincides with the internally generated horizontal blanking signal HBLNK,thenthis is field 1. If the synchronized VDpulsedoesnot coincide with HBLNK, then this isfield 2.Signals CK2H and HBLNK are both output signals of the horizontal divider circuit that is part of the line-locked clock generator. A reliable fielddetection is important forcorrect interlacing and de-interlacing and for thecorrect timing of the measurement lines of the black current loop. For the best noise margin, the edges of the VDpulse should be on approximately1⁄4and3⁄4 of the line, referred to the rising edges of the HD input signal.

b) If bus bit VSR = 0, the end of the VDpulse is used as reference for both field detection and start of vertical scan.

If VSR = 1, the starting edge is used.

42. Output range percentages mentioned for E-W control parameters are based on the assumption that the E-W modulator is dimensioned such that 400 µA variation in E-W output current of the IC is equivalent to 20% variation in picture width. In VGA mode, the E-W output current is proportional to the applied line frequency.

43. The IC has protection inputs for flash protection and overvoltage protection. a) The flash protection input is used to switch the horizontal drive output off immediately if a picture tube flashover

occurs, to protect the line output transistor. An external flash detection circuit is needed. When the flash input is pulled HIGH, the horizontal output is switched off and status bit FLS is set. When the input turns LOW again, the horizontal output is switched on immediately without I2C-bus intervention via the slow start procedure.

b) The overvoltage (X-ray) protection is combined with the EHT compensation input. When this protection is

activated, the horizontal drive can be directly switched off (via the slow stop procedure). It is also possible to continue the horizontal drive and onlyset status bit XPR in output byte 01 of the I2C-bus. The choice between the two modes of operation is made via bit PRD.

44. The ICs have a zoom adjustment possibility for the horizontal and vertical deflection. For this reason, an extra DAC is included in the vertical amplitude control, which controls the vertical scan amplitude between 0.75 and 1.38 of the

nominal scan. At an amplitude of 1.05 times the nominal scan, the output current is limited and the blanking of the RGBoutputs is activated, see Fig.14. In addition to the variation of the vertical amplitude, the picture can be vertically shiftedon the screen via the‘scroll’function. The nominal scan heightmustbe adjusted at a positionof 19H (25 DEC) of the vertical ‘zoom’ DAC and 1FH (31 DEC) for the vertical ‘scroll’ DAC.

45. The vertical scroll function is active only in the expand mode of the vertical zoom, i.e. at a DAC position larger than 10H (16 DEC).

46. With the vertical wait function, the start of the vertical scan can be delayed with respect to the incoming vertical sync pulse. The operation is different for the various scan modes, see Table 54 and Figs 12 and 13. The minimum value for the vertical wait is 8 line periods. If the setting is lower than 8, the wait period will remain 8 line periods.

47. In the TDA9330H and TDA9332H, the DAC output is I2C-bus controlled. In the TDA9331H, the DAC output voltage is proportional to the centre frequency of the line-oscillator. In TV mode, the output voltage will always be at the minimum value. In VGA mode, the output is at the minimum value for the lowest centre frequency (32 kHz) and at the maximum value for the highest centre frequency (48 kHz). The output impedance of the DAC output depends on the output voltage. The output consists of an emitter follower with an internal resistor of 50 kΩ to ground.

Adjustment of geometry control parameters

The deflection processor of the TDA933xH offers 15 control parameters for picture alignment, as follows:

For the vertical picture alignment;

• S-correction

• Vertical amplitude

• Vertical slope

• Vertical shift

• Vertical zoom

• Vertical scroll

• Vertical wait.

For the horizontal picture alignment;

• Horizontal shift

• Horizontal parallelogram

• Horizontal bow

• E-W width with extended range for the zoom function

• E-W parabola/width ratio

• E-W upper corner/parabola ratio

• E-W lower corner/parabola ratio

• E-W trapezium correction.

It is important to notice that the ICs are designed for use with a DC-coupled vertical deflection stage. This is why a vertical linearity alignment is not necessary (and therefore not available).

For a particular combination of picture tube type, vertical outputstage and E-W output stage,therequired values for the settings of S-correction and E-W corner/parabola ratio must be determined. These parameters can be preset via the I2C-bus and do not need any additional adjustment. Therest of the parameters arepreset with the mid-value of their control range, i.e.1FH, or withthe values obtained by previously-adjusted TV sets on the production line.

TDA933xH series

Toadjust the vertical shift and verticalslopeindependently of each other, a special service blanking mode can be entered by setting bit SBL HIGH. In this mode, the RGB outputs are blanked during the second half of the picture. There are two different methods for alignment of the picture in the vertical direction. Both methods use the service blanking mode.

The first method is recommended for picture tubes that have a marking for the middle of the screen. With the vertical shift control, the last line of the visible picture is positioned exactly in the middle of the screen. After this adjustment, the vertical shift should not be changed any more. The top of the picture is positioned by adjusting the vertical amplitude, and the bottom byadjusting the vertical slope.

Thesecond method is recommended for picturetubesthat have no marking for the middle of the screen. For this method, a video signal is required in which the middle of the picture is indicated (e.g. the white line in the circle test pattern). The beginning of the blanking is positioned exactly on the middleof the pictureusing the vertical slope control. The top and bottom of the picture are then positioned symmetrically with respect to the middle of the screen by adjusting the vertical amplitude and vertical shift.After this adjustment, thevertical shift has thecorrect setting and should not be changed any more.

If the vertical shift alignment is not required, VSH should be set to its mid-value, i.e. VSH = 1FH (31 DEC). The top of the picture is then positioned by adjusting the vertical amplitude and the bottom of the picture by adjusting the vertical slope.

After the vertical picture alignment, the picture is positioned in the horizontal direction by adjusting the E-W width,E-Wparabola/widthratioandhorizontalshift.Finally (if necessary), the left and right-hand sides of the picture are aligned in parallel by adjusting the E-W trapezium control.

The vertical shift control is intendedto compensate offsets in the external vertical output stage or in the picture tube. It can be shown that, without compensation, these offsets will result in a certain linearity error, especially with picture tubes that need large S-correction. In 1st-order approximation,the total linearity erroris proportional to the value of the offset and to the square of the S-correction that is needed. The necessity to use the vertical shift alignment depends on the expected offsets in the vertical output stage and picture tube, on the required value of the S-correction and on the demands upon vertical linearity.

2000 May 08 48

Additional horizontal corrections are possible using the parallelogram and bow controls.

To obtain the correct range of the vertical zoom function, the vertical geometry should be adjusted at a nominal setting of the zoomDAC at position 19H(25 DEC) and the vertical scroll DAC at 1FH (31 DEC).

SOLDERING Introduction to soldering surface mount packages

Thistextgivesa 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. Wavesoldering 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.

Reﬂow soldering

Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied tothe 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.

Wave soldering

Conventional single wave soldering is not recommended forsurfacemountdevices(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.

TDA933xH series

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): – 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.

• Forpackageswithleadson 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, thepackage 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.

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.

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.
