GENERAL DESCRIPTION The TDA8360, TDA8361 and TDA8362 are single-chip TV processors which contain nearly all small signal functions that are required for a colour television receiver. For a complete receiver the following circuits need to be added: a base-band delay line (TDA4661), a tuner and output stages for audio, video and horizontal and vertical deflection. Because of the different functional contents of the ICs the set maker can make the optimum choice depending on the requirements for the receiver. The TDA8360 is intended for simple PAL receivers (all PAL standards, including PAL-N and PAL-M are possible). The TDA8361 contains a PAL/NTSC decoder and has an A/V switch. For real multistandard applications the TDA8362 is available. In addition to the extra functions which are available in the TDA8361, the TDA8362 can handle signals with positive modulation and it supplies the signals which are required for the SECAM decoder TDA8395.
· Alignment-free PAL colour decoder for all PAL standards, including PAL-N and PAL-M. TDA8361 · PAL/NTSC colour decoder with automatic search system · Source selection for external audio/video (A/V) inputs (separate Y/C signals can also be applied). TDA8362 · Multistandard vision IF circuit (positive and negative modulation) · PAL/NTSC colour decoder with automatic search system · Source selection for external A/V inputs (separate Y/C signals can also be applied) · Easy interfacing with the TDA8395 (SECAM decoder) for multistandard applications.

TDA8360; TDA8361; TDA8362
To overcome this problem a speed-up circuit has been included which detects whether the AGC detector is activated every frame period. If, during a 3-frame period, no action is detected the speed of the system is increased. When the incoming signal has no peak white information (e.g. test lines in the vertical retrace period) the gain would be video signal dependent. To avoid this effect the circuit also contains a black level AGC detector which is activated when the black level of the video signal exceeds a certain level. The TDA8361 and TDA8362 contain a video identification circuit which is independent of the synchronization circuit. Therefore search tuning is possible when the display section of the receiver is used as a monitor. In the TDA8360 this circuit is only used for stable OSD at no signal input. In the normal television mode the identification output is connected to the coincidence detector, this applies to all three devices. The identification output voltage is LOW when no transmitter is identified. In this condition the sound demodulator is switched off (mute function). When a transmitter is identified the output voltage is HIGH. The voltage level is dependent on the frequency of the incoming chrominance signal.
The reference carrier for the video demodulator is obtained by means of passive regeneration of the picture carrier. The external reference tuned circuit is the only remaining adjustment of the IC. In the TDA8362 the polarity of the demodulator can be switched so that the circuit is suitable for both positive and negative modulated signals. The AFC circuit is driven with the same reference signal as the video demodulator. To ensure that the video content does not disturb the AFC operation a sample-and-hold circuit is incorporated; the capacitor for this function is internal. The AFC output voltage is 6 V. The AGC detector operates on levels, top sync for negative modulated and top white for positive modulated signals.The AGC detector time constant capacitor is connected externally. This is mainly because of the flexibility of the application. The time constant of the AGC system during positive modulation (TDA8362) is slow, this is to avoid any visible picture variations. This, however, causes the system to react very slowly to sudden changes in the input signal amplitude.

Sound circuit The sound bandpass and trap filters have to be connected externally. The filtered intercarrier signal is fed to a limiter circuit and is demodulated by means of a PLL demodulator. The PLL circuit tunes itself automatically to the incoming signal, consequently, no adjustment is required. The volume is DC controlled. The composite audio output signal has an amplitude of 700 mV RMS at a volume control setting of -6 dB. The de-emphasis capacitor has to be connected externally. The non-controlled audio signal can be obtained from this pin via a buffer stage. The amplitude of this signal is 350 mV RMS. The TDA8361 and TDA8362 external audio input signal must have an amplitude of 350 mV RMS. The audio/video switch is controlled via the chrominance input pin. Synchronization circuit The sync separator is preceded by a voltage controlled amplifier which adjusts the sync pulse amplitude to a fixed level. The sync pulses are then fed to the slicing stage (separator) which operates at 50% of the amplitude. The separated sync pulses are fed to the first phase detector and to the coincidence detector. The coincidence detector is used for transmitter identification and to detect whether the line oscillator is synchronized. When the circuit is not synchronized the voltage on the peaking control pin (pin 14) is LOW so that this condition can be detected externally. The first PLL has a very high static steepness, this ensures that the phase of the picture is independent of the line frequency. The line oscillator operates at twice the line frequency.
TDA8360; TDA8361; TDA8362
When the pin is left open-circuit the trap is switched off so that the circuit can also be used for S-VHS applications. The luminance delay line and the delay for the peaking circuit are also realised by means of gyrator circuits. Colour decoder The colour decoder in the various ICs contains an alignment-free crystal oscillator, a colour killer circuit and colour difference demodulators. The 90° phase shift for the reference signal is achieved internally. Because the main differences of the 3 ICs are found in the colour decoder the various types will be discussed. TDA8360 This IC contains only a PAL decoder. Depending on the frequency of the crystals which are connected to the IC the decoder can demodulate all PAL standards. Because the horizontal oscillator is calibrated by using the crystal frequency as a reference the 4.4 MHz crystal must be connected to pin 35 and the 3.5 MHz crystal to pin 34. When only one crystal is connected to the IC the other crystal pin must be connected to the positive supply rail via a 47 k resistor. For applications with two 3.5 MHz crystals both must be connected to pin 34 and the switching between the crystals must be made externally. Switching of the crystals is only allowed directly after the vertical retrace. The circuit will indicate whether a PAL signal has been identified by the colour decoder via the saturation control pin. When two crystals are connected to the IC the output voltage of the video identification circuit indicates the frequency of the incoming chrominance signal.
The oscillator network is internal. Because of the spread of internal components an automatic adjustment circuit has been added to the IC. The circuit compares the oscillator frequency with that of the crystal oscillator in the colour decoder. This results in a free-running frequency which deviates less than 2% from the typical value. The circuit employs a second control loop to generate the drive pulses for the horizontal driver stage. X-ray protection can be realised by switching the pin of the second control loop to the positive supply line. The detection circuit must be connected externally. When the X-ray protection is active the horizontal output voltage is switched to a high level. When the voltage on this pin returns to its normal level the horizontal output is released again. The IC contains a start-up circuit for the horizontal oscillator. When this feature is required a current of 6.5 mA has to be supplied to pin 36. For an application without start-up both supply pins (10 and 36) must be connected to the 8 V supply line. The drive signal for the vertical ramp generator is generated by means of a divider circuit. The RC network for the ramp generator is external. Integrated video filters The circuit contains a chrominance bandpass and trap circuit. The filters are realised by means of gyrator circuits and are automatically tuned by comparing the tuning frequency with the crystal frequency of the decoder. In the TDA8361 and TDA8362 the chrominance trap is active only when the separate chrominance input pin is connected to ground or to the positive supply voltage and when a colour signal is recognized.

The conditions are: · Signal identified at fosc = 3.6 MHz; VO = 6 V · Signal identified at fosc = 4.4 MHz (or no colour); VO = 8 V. This information can be used to switch the sound bandpass filter and trap filter. TDA8361 This IC contains an automatic PAL/NTSC decoder. The conditions for connecting the reference crystals are the same as for the TDA8360. The decoder can be forced to PAL when the hue control pin is connected to the positive supply voltage via a 5 k or 10 k resistor (approximately). The decoder cannot be forced to the NTSC standard. It is also possible to see if a colour signal is recognized via the saturation pin. TDA8362 In addition to the possibilities of the TDA8361, the TDA8362 can co-operate with the SECAM add-on decoder TDA8395. The communication between the two ICs is achieved via pin 32. The TDA8362 supplies the reference signal (4.43 MHz) for the calibration system of the TDA8395, identification of the colour standard is via the same connection. When a SECAM signal is detected by the TDA8395 the IC will draw a current of 150 µA. When TDA8362 has not identified a colour signal in this condition it will go into the SECAM mode, that means it will switch off the R-Y and B-Y outputs and increase the voltage level on pin 32.
TDA8360; TDA8361; TDA8362
This voltage will switch off the colour-killer in the TDA8395 and switch on the R-Y and B-Y outputs of the TDA8395. Forcing the system to the SECAM standard can be achieved by loading pin 32 with a current of 150 µA. Then the system manager in the TDA8362 will not search for PAL or NTSC signals. Forcing to NTSC is not possible. For PAL/SECAM applications the input signal for the TDA8395 can be obtained from pin 27 (hue control) when this pin is connected to the positive supply rail via the 5 k or 10 k resistor. An external source selector is required by the TDA8395/TDA8362 combination for PAL/SECAM/NTSC applications. RGB output circuit The colour difference signals are matrixed with the luminance signal to obtain the RGB signals. Linear amplifiers have been chosen for the RGB inputs so that the circuit is suitable for incoming signals from the SCART connector. The contrast and brightness controls operate on internal and external signals. The fast blanking pin has a second detection level at 3.5 V. When this level is exceeded the RGB outputs are blanked so that "On-Screen-Display" signals can be applied to the outputs. The output signal has an amplitude of approximately 4 V, black-to-white, with nominal input signals and nominal control settings. The nominal black level is 1.3 V.

It is possible to start the horizontal oscillator when a current of 5.5 mA is supplied to this pin. In this condition the main part of the IC is not active and this results in the frequency of the oscillator not being controlled at the correct value. Consequently, the oscillator frequency will be higher than normal, the maximum deviation will be 75%. When the start-up function is used the maximum voltage on pin 36 must be limited to 8.8 volts. 2. On set AGC. 3. This parameter is not tested during production and is just given as application information for the designer of the television receiver. 4. Measured at 10 mV RMS top sync input signal. 5. So called projected zero point, i.e. with switched demodulator. 6. Measured in accordance with the test line given in Fig.11. For the differential phase test the peak white setting is reduced to 87%. The differential gain is expressed as a percentage of the difference in peak amplitudes between the largest and smallest value relative to the subcarrier amplitude at blanking level. The phase difference is defined as the difference in degrees between the largest and smallest phase angle. 7. 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. 8. This figure is valid for the complete video signal amplitude (peak white-to-black), see Fig.12. 9. Insertion (suppression of the interference pulses) to a level of 2.6 V is active only during a strong input signal. This is because the noise inverter has a negative effect on the sound performance at a weak input signal. 10. The test set-up and input conditions are given in Fig.13.

TDA8360; TDA8361; TDA8362
12. To obtain a good noise immunity of the AGC circuit the AGC detector is gated during the sync pulse. This gating is switched off during the vertical retrace to avoid disturbances of the signal amplitude due to phase errors of the incoming video signal which are caused by the head-switching of VCRs. 13. When the leakage current of the capacitor exceeds this value it will result in a reduced performance of the AGC (amplitude variation during line or frame) but it will not result in a hang-up situation. 14. The AFC slope is directly related to the Q-factor of the demodulator tuned circuit. The given AFC steepness is obtained with a Q-factor of 60. When a lower steepness is required this can be obtained by connecting an external resistor to the AFC output (the output impedance is 50 k). The AFC off-set is tested with a double sideband input signal and with the reference tuned circuit tuned to minimum AGC voltage (optimum tuning for the demodulator). 15. For positive modulated signals the FM sound demodulator for the sound is not required. This is because the sound signal is amplitude modulated. Therefore the TDA8362 can be switched to positive modulation via the de-emphasis pin (pin 1). When switched to positive modulation the audio switch is set to `external' so that the demodulated audio signal can be supplied to the input. The option between AM sound and SCART audio signals is achieved by means of an external switch. 16. The sound IF input is combined with the AF volume control. The IF signal is internally AC coupled to the limiter amplifier. The volume control voltage must be supplied to this pin via a resistor. 17. VI = 100 mV RMS; FM: 1 kHz, f = ±50 kHz. 18. VI = 50 mV RMS, f = 4.5/5.5 MHz; FM: 70 Hz ±50 kHz deviation AM: 1 kHz at 30% modulation. 19. VI = 100 mV RMS, 5.5 MHz; FM: 1 kHz, ±17.5 kHz deviation; 15 kHz bandwidth; audio attenuator at -6 dB. 20. Audio attenuator at -20 dB; temperature range 10 to 50 °C. 21. In the TDA8361 and TDA8362 the audio and CVBS switches are controlled via the chrominance input pin. Table 1 lists the various possibilities. When the DC voltage has a value between 3 and 5 V the switches are set to the S-VHS position. The chrominance trap is then switched off and separate Y and chrominance signals have to be applied to the inputs (the audio switch is set to external in this condition). The audio switch is also set to external when the IF amplifier is switched to positive modulation (see also note 15). 22. Signal with negative-going sync. Amplitude includes sync pulse amplitude. 23. This parameter is measured at nominal settings of the various control voltages. 24. Burst amplitude; for a colour bar with 75% saturation the chrominance signal amplitude is 660 mV (p-p). 25. Nominal contrast is specified as maximum contrast -3 dB. Nominal saturation as maximum -12 dB. The nominal brightness control voltage is 2.5 V. 26. When the data blanking input pulse exceeds a level of 4 V the RGB outputs are blanked. In this condition it is possible to supply `On-Screen-Display' signals to the outputs. This blanking overrules both the internal and external RGB signals. 27. The -3 dB bandwidth of the circuit can be calculated by means of the following equation: 1 f 3 dB = f osc 1 ------- 2Q

and is realised with a transversal peaking filter having delay sections of 160 ns each. In the `neutral' setting K = 0 and in the minimum setting K = -0.5. The peaking signal amplifier is linear for 250 ns step input signals up to 50 IRE units. For higher amplitudes the marginal gain is reduced. When the horizontal PLL is not synchronized (no signal present at the video input) the peaking control voltage is pulled down by means of an internal current. This information can be used to detect whether an input signal is available. 29. Slicing level independent of sync pulse amplitude. 30. The horizontal and vertical sync are stable while processing Copy Guard signals and signals with phase shifted sync pulses (stretched tapes). Trick mode conditions of the VCR will also not disturb the synchronization. The value given is the delay caused by the vertical sync pulse integrator. The integrator has been designed such that the vertical sync is not disturbed for special anti-copy tapes with vertical sync pulses with an on/off time of 10/22 µs. 31. To obtain a good performance for both weak signal and VCR playback the time constant of the first control loop is switched depending on the input signal condition. Therefore the circuit contains a noise detector and the time constant is switched to `slow' when excessive noise is present in the signal (only when the internal video signal is selected, when the video switch is in the external mode the time constant is always `fast'). In the `fast' mode during the vertical retrace time the phase detector current is increased 50% so that phase errors due to head-switching of the VCR are corrected as soon as possible. When no video signal is received the time constant of the first loop is switched to `very slow'. This ensures a stable OSD when the receiver is switched to a channel without transmitter. The output current of the phase detector for the various conditions is shown in Table 2. 32. Picture shift can be obtained by means of a variable external load on the second phase detector. The control range is ±2 µs; the required current for this phase shift is ±6 µA. 33. The vertical blanking pulse in the RGB outputs has a width of 22 or 17.5 lines (50 or 60 Hz system). The width of the vertical sync pulse in the sandcastle pulse is 14 lines. This is to prevent a phase distortion on top of the picture due to a timing modulation of the incoming flyback pulse. 34. The timing pulses for the vertical ramp generator are obtained from the horizontal oscillator via a divider circuit. This divider circuit has 2 search modes of operation: The `large window' mode is switched on when the circuit is not synchronized or, when a non-standard signal is received (the number of lines per frame in the 50 Hz mode is between 311 and 314 and in the 60 Hz mode between 261 and 264). In the search mode the divider can be triggered between line 244 and line 361 (approximately 45 to 64.5 Hz) The `narrow window' mode is switched on when more than 15 successive vertical sync pulses are detected in the narrow window. When the circuit is in the standard mode and a vertical sync pulse is missing the retrace of the vertical ramp generator is started at the end of the window. Consequently, the disturbance of the picture is very small. The circuit will switch back to the search window when, for 6 successive vertical periods, no sync pulses are found within the window. 35. This precorrection is intended to compensate for non-linearity of AC coupled vertical output stages. The value given indicates the amplitude of the correction waveform with respect to the sawtooth amplitude. 36. At a chrominance input voltage (related to CVBS2) of 660 mV (p-p) (colour bar with 75% saturation i.e. burst signal amplitude 300 mV (p-p)) the dynamic range of the ACC is +6 and -20 dB.

37. All frequency variations are referenced to 3.58/4.43 MHz carrier frequency. All oscillator specifications are measured with the Philips crystal series 9922 520. If the spurious response of the 4.43 MHz crystal is lower than -3 dB with respect to the fundamental frequency for a damping resistance of 1 k, oscillation at the fundamental frequency is guaranteed. The spurious response of the 3.58 MHz crystal must be lower than -3 dB with respect to the fundamental frequency for a damping resistance of 1.5 k. The catching and detuning range are measured for nominal crystal parameters. These are: a) load resonance frequency f0 (CL = 20 pF) = 4.433619 or 3.579545 MHz b) motional capacitance CM = 20.6 fF (4.43 MHz crystal) or (3.58 MHz crystal) c) parallel capacitance C0 = 5.5 pF (4.43 MHz crystal) or 4.5 pF (3.58 MHz crystal). The actual load capacitance in the application should be CL = 18 pF to account for parasitic capacitances on and off chip. The free-running frequency of the oscillator can be checked by pulling the saturation control pin to the positive supply rail. In that condition the colour killer is not active so that the frequency off-set is visible on the screen. When two crystals are connected to the IC the circuit must be forced to one of the crystals during this test to prevent the oscillator continuously switching between the two frequencies. 38. In the TDA8362 the hue control pin has a double function. When the control voltage has a value of 0 to 5 V (normal control range) the hue can be controlled when NTSC signals are decoded. When this voltage is increased to a value greater than 5.5 V the decoder is forced to the PAL standard. When this pin is connected to the positive supply line via a 10 k resistor the selected CVBS signal, of the CVBS switch, is available. This signal can be applied to the SECAM decoder TDA8395. The phase shift of the hue control can be measured at the colour difference outputs (pins 30 and 31). 39. The -(R-Y) and -(B-Y) signals are demodulated with the 90° phase difference of the reference carrier and a gain ratio -(B-Y)/-(R-Y) = 1.78. The matrixing to the required signals is achieved in the control part. 40. This value indicates the bandwidth of the complete chrominance circuit including the chrominance bandpass filter. The bandwidth of the demodulator low-pass filter is approximately 1 MHz. 41. The reference signal for the TDA8395 is available only when the crystal oscillator is operating at a frequency of 4.43 MHz. When a SECAM signal is identified this signal is only available during the vertical retrace period thus avoiding crosstalk with the incoming SECAM signal during scan. 42. When one of the three output signals exceeds this level the gain of the amplifiers is reduced. This is achieved by a reduction of contrast and thus avoids clipping of the output signals. The discharge current at pin 25 is 0.2 mA. When the black level exceeds a value of 2 V the maximum peak-to-peak value of the video output signal will be less than 4 V (p-p); this is due to the operation of the peak-white limiter. 43. The signal-to-noise ratio is specified as a peak-to-peak signal with respect to RMS noise (bandwidth 5 MHz). During the measurement the peaking control voltage is set to nominal. 44. The typical free running frequency is dependent on the crystal which is used for calibration. With 4.4 MHz the typical free running frequency is 15625, with 3.58 MHz the typical free running frequency is 15734. Calibration during start-up is always carried out with a 4.4 MHz crystal if no forced mode is used.

SOLDERING Plastic dual in-line packages BY DIP OR WAVE The maximum permissible temperature of the solder is 260 °C; this temperature must not be in contact with the joint for more than 5 s. The total contact time of successive solder waves must not exceed 5 s. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit.
REPAIRING SOLDERED JOINTS Apply the soldering iron below the seating plane (or not more than 2 mm above it). If its temperature is below 300 °C, it must not be in contact for more than 10 s; if between 300 and 400 °C, for not more than 5 s.
