The SDA and SCL inputs meet the I2C-bus specification, the other three inputs are TTL compatible. FUNCTIONAL DESCRIPTION Input signals (pins 12, 13, 14, 17 and 18) The TDA9151B requires three signals for minimum operation (apart from the supply). These signals are the line-locked clock (LLC) and the two I2C-bus signals (SDA and SCL). Without the LLC the device will not operate because the internal synchronous logic uses the LLC as the system clock. The LLC frequency can be divided-by-two internally by connecting LLCS (pin 5) to ground thereby enabling the prescaler. I2C-bus transmissions are required to enable the device to perform its required tasks. Once started the IC will use the HA and/or VA inputs for synchronization. If the LLC is not July 1994 The LLC timing is given in the Chapter “Characteristics”. 5 Philips Semiconductors Preliminary specification Programmable deflection controller TDA9151B • Logic 0: I2C-bus commands – after a successful read of the status byte.

Switching of the prescaler is only allowed when LFSS is LOW. It is highly recommended to hard wire LLCS to ground or VCC.

July 1994 9 Philips Semiconductors Preliminary specification Programmable deflection controller TDA9151B Horizontal part (pins 1, 2, 13, 19 and 20 CLAMPING PULSE SYNCHRONIZATION PULSE The clamping pulse width is 21 internal clock periods. The shift, with respect to HA can be varied from 35 to 49 clock periods in 7 steps via the I2C-bus, clamp shift byte subaddress 0A, as illustrated in Fig.9. It is possible to suppress the clamping pulse during wait, stop and protection modes with control bit CSU. This will avoid unwanted reset of the TDA4680/81 (only used in those circuits). The HA input (pin 13) is a TTL-compatible CMOS input. Pulses on this input have to fulfil the timing requirements as illustrated in Fig.6. For correct detection the minimum pulse width for both the HIGH and LOW periods is 2 internal clock periods. FLYBACK INPUT PULSE HORIZONTAL BLANKING The HFB input (pin 1) is a CMOS input. The delay of the centre of the flyback pulse to the leading edge of the HA pulse can be set via the I2C-bus with the horizontal phase byte (subaddress 08), as illustrated in Fig.7. The resolution is 6-bit. The start of the horizontal blanking pulse is minimum 38 and maximum 41 clock periods before the centre of the flyback pulse, depending on the fclk/fH ratio K in accordance with 41 − (432 − K). Stop of the horizontal blanking pulse is determined by the trailing edge of the HFB pulse at the horizontal blanking slicing level crossing as illustrated in Fig.10. OUTPUT PULSE The HOUT pulse (pin 20) is an open-drain NMOS output. The duty factor for this output is typically 52⁄48 (conducting/non-conducting) during normal operation. A soft start causes the duty factor to increase linearly from 5 to 52% over a minimum period of 2000 lines in 2000 steps. VERTICAL BLANKING The vertical blanking pulse starts two internal clock pulses after the rising edge of the VA pulse. During this interval a small guard pulse, generated during flyback by the vertical power output stage, must be inserted. Stop vertical blanking is effected at the end of the blanking interval only when the guard pulse is present (see Section “Vertical guard”). OFF-CENTRE SHIFT The OFCS output (pin 19) is a push-pull CMOS output which is driven by a pulse-width modulated DAC. By using a suitable interface, the output signal can be used for off-centre shift correction in the horizontal output stage. This correction is required for HDTV tubes with a 16 × 9 aspect ratio and is useful for high performance flat square tubes to obtain the required horizontal linearity. For applications where off-centre correction is not required, the output can be used as an auxiliary DAC. The OFCS signal is phase-locked with the line frequency. The off-centre shift can be set via the I2C-bus, subaddress 09, with a 6-bit resolution as illustrated in Fig.8. The start scan setting determines the end of vertical blanking with a 6-bit resolution in steps of one line via the I2C-bus subaddress 02 (see Figs 11, 12 and 13). VERTICAL GUARD In the vertical blanking interval a small unblanking pulse is inserted. This pulse must be filled-in by a blanking pulse or guard pulse from the vertical power output stage which was generated during the flyback period. In this condition the sandcastle output acts as guard detection input and requires a minimum 800 µA input current. This current is sensed during the unblanking period. Vertical blanking is only stopped at the end of the blanking interval when the inserted pulse is present. In this way the picture tube is protected against damage in the event of missing or malfunctioning vertical deflection (see Figs 11, 12 and 13). SANDCASTLE The DSC input/output (pin 2) acts as a sandcastle generating output and a guard sensing input. As an output it provides 2 levels (apart from the base level), one for the horizontal and vertical blanking and the other for the video clamping. As an input it acts as a current sensor during the vertical blanking interval for guard detection. July 1994 10 Philips Semiconductors Preliminary specification Programmable deflection controller TDA9151B Vertical place generator in constant slope mode (MS = logic 1) Vertical part (pins 6, 8, 10, 11 and 12) SYNCHRONIZATION PULSE In this mode the slope can be programmed directly with a two byte value on subaddress 0C (MSB) and 0D (LSB). When the actual number of lines is greater than the programmed number of lines, the circuit will enter the stop state in which the differential vertical output current remains 100% or drops to 20% (programmable with control bit VPR). The programmed value for the slope is the required number of lines multiplied by 72. The programming limits are; minimum 200 × 72 and maximum 910 × 72. The VA input (pin 12) is a TTL-compatible CMOS input. Pulses at this input have to fulfil the timing requirements as illustrated in Fig.6. For correct detection the minimum pulse width for both the HIGH and LOW period is 2 internal clock periods. For further requirements on minimum pulse width see also Section “De-interlace”. VERTICAL PLACE GENERATOR An overview of the various modes of operation of the vertical place generator is illustrated in Fig.13. A vertical expansion is obtained with a combination of slope data and a programmable wait status, at subaddress 0E. The wait status is selected with control bit MS and can only be activated in the constant slope mode. The wait state is an 8-bit value, programmable from 0 to 255. The actual wait state is one line longer than the programmed value. If blanking is applied during stop and wait status the differential output current will be the same with VPR selected value (20 or 100%). With control bit CPR a compress to 75% of the adjusted values is possible in all modes of operation. This control bit is used to display 16 : 9 standard pictures on 4 : 3 displays. No new adjustment of other corrections, such as corner and S-correction, is required. With control bit VPR a reduction of the current during clipping, wait and stop modes to 20% of the nominal value can be selected, which will reduce the dissipation in the vertical drive circuits. DE-INTERLACE With de-interlace on (DINT = logic 0), the VA pulse is sampled with LLC at a position supplied by control bit DIP (de-interlace phase). Vertical place generator in adaptive mode (MS = logic 0) The vertical start-scan data (subaddress 02) determines the vertical placement in the total range of 64 × 432 clock periods in 63 steps. The maximum number of synchronized lines per scan is 910 with an equivalent field frequency of 17.2 or 34.4 Hz for fH = 15625 or 31250 Hz respectively. When DIP = logic 0 sampling takes place 42 clock pulses after the leading edge of HA (T = Tline × 42/432). When DIP = logic 1 sampling takes place 258 clock pulses after the leading edge of HA (T = Tline × 258/432). The minimum number of synchronized lines per scan is 200 with an equivalent field frequency of 78 or 156 Hz for fH = 15 625 or 31250 Hz respectively. The distance between the two selectable sampling points is (Tline × (258 − 42)/432) which is exactly half a line, thus de-interlace is possible in two directions. If the VA pulse is not present, the number of lines per scan will increase to 910.2. If the LLC is not present the vertical blanking will start within 2 µs. The duration of the VA pulse must, therefore, be sufficient to enable the HA pulse to caught, in this event an active time of minimum of half a line (see Fig.14 which has an integration time of Tline × 1⁄4 for the VA pulse). Amplitude control is automatic, with a settling time of 1 to 2 new fields and an accuracy of either 16/12 or 48/12 lines depending on the value of the GBS bit. With de-interlace off, the VA pulse is sampled with the system clock. The leading edge is detected and used as the vertical reset. Selection of the positive or negative leading edge is achieved by the control bit VAP. Differences in the number of lines per field, as can occur in TXT or in multi-head VTR, will not affect the amplitude setting providing the differences are less than the value selected with GBS. This is called amplitude control guardband. The difference sequence and the difference sequence length are not important. July 1994 11 Philips Semiconductors Preliminary specification Programmable deflection controller TDA9151B Two modes of protection are available with the aid of control bit PRD. VERTICAL GEOMETRY PROCESSING The vertical geometry processing is DC-coupled and therefore independent of field frequency. The external resistive conversion (RCONV) at pin 8 sets the reference current for both the vertical and EW geometry processing. A useful range is 100 to 150 µA, the recommended value is 120 µA. • With PRD = logic 1 the protection mode is selected, HOUT will be defeated and the PROT bit in the status word is set if the input voltage is above 3.9 V. Thus the deflection stops and EW output current is zero, while the vertical output current is reduced to 20% of the adjusted value. A new start of the circuit is I2C-bus controlled with the user software. VERTICAL OUTPUTS • With PRD = logic 0 the detection mode is selected, HOUT will not be defeated and the over voltage information is only written in the PROT status bit and can be read by the I2C-bus. The vertical outputs VOUTA and VOUTB on pins 10 and 11 together form a differential current output. The vertical amplitude can be varied over the range 80 to 120% in 63 steps via the I2C-bus (subaddress 00). Vertical S-correction is also applied to these outputs and can be set from 0 to 16% by subaddress 01 with a 6-bit resolution. All further actions, such as a write of the LFSS bit, are achieved by the I2C-bus. They depend on the configuration used and are defined by user software. The vertical off-centre shift (OFCS) shifts the vertical deflection current zero crossing with respect to the EW parabola bottom. The control range is −1.5 to +1.5% (±1⁄8 × I8) in 7 steps set by the least significant nibble at subaddress 03. Flash detection/protection input (pin 9) The FLASH input is a CMOS input with an internal pull-up current of approximately 8 µA. When a negative-going edge crosses the 0.75 V level a restart will be executed with a soft start of approximately 2000 lines, such as in the soft-start mode. When the function is not used pin 9 can be connected to ground, VCC or left open-circuit, the internal pull-up current source will prevent any problems. However a hard wired connection to VCC or ground is recommended when the function is not used. EW GEOMETRY PROCESSING The EW geometry processing is DC coupled and therefore independent of field frequency. RCONV sets the reference current for both the vertical and EW geometry processing. The EW output is an ESD-protected single-ended current output. The EW width/width ratio can be set from 100 to 80% in 63 steps via subaddress 04 and the EW parabola/width ratio from 0 to 20% via subaddress 05. The EW corner/EW parabola ratio has a control range of −40 to 0% in 63 steps via subaddress 06. EHT compensation (pin 7) The EHT input is a CMOS input. The EHT compensation input permits scan amplitude modulation should the EHT supply not be perfect. For correct tracking of the vertical and horizontal deflection the gain of the EW output stage, provided by the ratio RCONV-EW/RCONV, must be 1⁄16Vscan × Vref (see Fig.15). The EW trapezium correction can be set from −1.5 to +1.5% in 7 steps via the most significant nibble at subaddress 03. The input for EHT compensation can be derived from an EHT bleeder or from the picture tubes aquadag (subaddress 0B, bit BLDS). BULT GENERATOR The Bult generator makes the EW waveform continuous (see Fig.21). EHT compensation can be set via subaddress 07 in 63 steps allowing a scan modulation range from −10 to +9.7%. Protection input (pin 3) The protection input (PROT) is a CMOS input. The input voltage must be EHT scaled and has the following characteristics: July 1994 12 July 1994 1 300 Ω 19 2 300 Ω 18 3 300 Ω 17 4 5 300 Ω TDA9151B 15 6 14 300 Ω 7 300 Ω 13 300 Ω 8 12 300 Ω 9 300 Ω 11 10 MBD906 Programmable deflection controller 13 Fig.4 Internal circuitry. 300 Ω 16 handbook, full pagewidth 20 Philips Semiconductors Preliminary specification TDA9151B INTERNAL CIRCUITRY July 1994 14 VCC ( 8 V) SCL SDA HOUT R77 1 kΩ R76 R75 100 Ω 100 Ω 20 19 18 17 16 OFCS 100 nF 22 µF 1 2 3 4 5 15 VCC ( 8 V) 6 14 LLC TDA9151B 7 C89 8 13 HA C95 9 12 VA 10 HFB 23 V (peak) R85 15 kΩ R84 3.3 kΩ R99 3.3 kΩ 100 nF C97 R88 R87 4.7 kΩ 39 kΩ 100 nF Zener diode R107 82 kΩ 100 µF C105 45 V (vert) 100 µF C105 16 V (vert) R105 3 kΩ 13 12 11 10 9 8 7 TDA8350 6 5 4 3 2 1 IE5 3 2 1 MBD907 100 nF C110 R113 330 Ω R113 IE5 vertical deflection coil 33 V EW-OUT LV R117 Programmable deflection controller Fig.5 Application diagram.

For all other frequencies the expected supply current will be as shown in Table 6 (fclk is the internal clock frequency, fLLC is the internal clock frequency applied to pin 14). 2. When the prescaler is on, one in two LLC HIGH periods is omitted. 3. For 16 kHz operation the minimum value of the control range is 5.7 µs. With 1⁄2tFB = 5.7 µs the minimum storage time is 0 and the maximum is 18 µs. For 32 kHz operation the minimum value of the control range is 0 µs. With 1⁄2tFB = 2.85 µs the minimum storage time is 0 and the maximum is 9 µs. 4. The k factor is defined as the amount of correction of a phase step. Thus with k = 0.5 a 50% correction of the error takes place each line. The resulting step response now becomes kn, with n the line number after the step. 5. The sigma value (σ) of the jitter with respect to LLC (HA) at fH = 32 kHz and a storage time of 5 µs. Measurement of σ is carried out during 200 lines in the active scan, the resulting peak-to-peak value is approximately 6σ. The visible jitter on the screen will be higher than the peak-to-peak jitter, depending on the deflection stage. 6. DAC values: vertical amplitude = 31; EHT = 0; SHIFT = 3; SCOR = 0. 7. Value is a percentage of I10 − I11. 8. The linearity error is measured without S-correction and based on the same measurement principle as used for the screen. Measuring method: divide the output signal I10 − I11 into 22 equal parts, ranging from 1 to 22 inclusive. Measure the value of two succeeding parts called one block starting with part 2 and 3 (block 1) and ending with part 20 and 21 (block 10). Thus part 1 and 22 are unused. ak – a ( k + 1) Linearity error for adjacent blocks = -----------------------------a avg a max – a min Linearity error for non-adjacent blocks = -----------------------------a avg Where a = amplitude, ak = amplitude block k and aavg = average amplitude. 9. Minimum available range. 10. Selection of test mode. When the EW output is pulled above VCC − 0.5 V a special test mode is entered in which the prescaler and the clock detector are disabled. 11. DAC values: vertical amplitude = 31; EHT = 0. 12. The value of −40% (typically 46%) corresponds with data 3F (hexadecimal) and implies maximum 4th order compensation.
