GENERAL DESCRIPTION
The TDA8366 is an I
2
C-bus controlled PAL/NTSC TV processor. The circuit has been designed for use with the baseband chrominance delay line TDA4665 and for DC-coupled vertical and East-West (EW) output stages.
The device can process both CVBS and Y/C input signals and has a linear RGB-input with fast blanking.
The peaking circuit generates asymmetrical overshoots (the amplitude of the ‘black’ overshoots is approximately 2 times higher as the one of the ‘white’ overshoots) and contains a (defeatable) coring function.
The RGB control circuit contains a black-current stabilizer circuit with internal clamp capacitors. The white point of the picture tube is adjusted via the I
2
C-bus.
The deflection control circuit provides a drive pulse for the horizontal output stage, a differential sawtooth current for the vertical output stage and an East-West drive current for the East-West output stage.These signals can be manipulated for geometry correction of the picture.
The supply voltage for the IC is 8 V. The IC is available in an SDIP package with 52 pins and in a QFP package with 64 pins (see Chapter “Ordering information”).
The pin numbers indicated in this document are referenced to the SDIP52; SOT247-1 package; unless otherwise indicated.

FUNCTIONAL DESCRIPTION Vision IF amplifier
The IF-amplifier contains 3 AC-coupled control stages with a total gain control range which is in excess of 66 dB. The sensitivity of the circuit is comparable with that of modern IF-ICs. 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.
The polarity of the demodulator can be switched via the I
2
C-bus in such a way 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 avoid that the video content disturbs the AFC operation a sample-and-hold circuit is applied for signals with negative modulation. The capacitor for this function is internal. The AFC information is supplied to the tuning system via the I2C-bus.
The AGC-detector operates on top-sync or top white-level depending on the polarity of the demodulator. The demodulation polarity is switched via the I2C-bus. The AGC detector time-constant capacitor is connected externally (this mainly because of the flexibility of the application). The time-constant of the AGC system during positive modulation is rather long to avoid visible variations of the signal amplitude. To obtain an acceptable speed of the AGC system a circuit has been included which detects whether the AGC detector is activated every frame period. When during 3 frame periods no action is detected the speed of the system is increased.
The circuit contains 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. The identification output is supplied to the tuning system via the I2C-bus. The information of this identification circuit can also be used to switch the phase-1 (ϕ1) loop to a low gain when no signal is received so that a stable OSD display is obtained. The coupling of the video identification circuit with the ϕ1loop can be switched on and off via the I2C-bus.
Synchronization circuit
The sync separator is preceded by a controlled amplifier which adjusts the sync pulse amplitude to a fixed level. These pulses are fed to the slicing stage which is operating at 50% of the amplitude.
The separated sync pulses are fed to the first phase detector and to the coincidence detector. This coincidence detector is only used to detect whether the line oscillator is synchronized and not for transmitter identification. The first Phase-Locked Loop (PLL) has a very high-statical steepness so that the phase of the picture is independent of the line frequency.
The line oscillator is running at twice the line frequency. The oscillator capacitor is internal. Because of the spreads of internal components an automatic adjustment circuit has been added to the IC. It compares the oscillator frequency with that of the crystal oscillator in the colour decoder.
To protect the horizontal output transistor the horizontal drive is switched-off when a power-on-reset is detected. The frequency of the oscillator is calibrated again when all subaddress bytes have been sent. When the oscillator has the right frequency the calibration stops and the horizontal drive is switched-on again via the soft start procedure (standby bit in normal mode). When the IC is switched-on the same procedure is followed.
When the coincidence detector indicates an out-of-lock situation the calibration procedure is repeated.
The circuit has a second control loop to generate the drive pulses for the horizontal driver stage. During the start-up procedure the duty cycle of the horizontal output pulse increases from 0 to 50% in approximately 100 lines.
The vertical sawtooth generator drives the vertical output and EW correction drive circuits. The geometry processing circuits provide control of horizontal shift, EW width, EW parabola/width ratio, EW corner/parabola ratio, trapezium correction, vertical shift, vertical slope, vertical amplitude, and the S-correction. All these controls can be set via the I
2
C-bus. The geometry processor has a differential current

output for the vertical drive signal and a single-ended output for the EW drive. Both the vertical drive and the EW drive outputs can be modulated for EHT compensation. The EHT compensation pin is also used for overvoltage protection.
The geometry processor also offers the possibilities for vertical compression (for display of 16 : 9 pictures on a 4 : 3 screen) and vertical expansion (for display of 4 : 3 pictures on a 16 : 9 screen with full picture width, or for display of ‘letter-box’ transmissions on a 4 : 3 screen with full picture height). For the expand mode it is possible to shift the picture vertically (only one fixed position).
Also the de-interlace of the vertical output can be set via the I2C-bus.
To avoid damage of the picture tube when the vertical deflection fails the guard output current of the TDA8350 can be supplied to the sandcastle output. When a failure is detected the RGB-outputs are blanked and a bit is set (NDF) in the status byte of the I2C-bus. When no vertical deflection output stage is connected this guard circuit will also blank the output signals. This can be overruled by means of the EVG bit of subaddress 0A (see Table 1).
Integrated video filters
The circuit contains a chrominance bandpass and trap circuit. The chrominance trap filter in the luminance path is designed for a symmetrical step response behaviour. The filters are realized by means of gyrator circuits and they are automatically tuned by comparing the tuning frequency with the crystal frequency of the decoder. The luminance delay line and the delay for the peaking circuit are also realized by means of gyrator circuits.
It is possible to connect a Colour Transient Improvement (CTI) or Picture Signal Improvement (PSI) IC to the TDA8366. Therefore the luminance signal which has passed the filter and delay line circuit is externally available. The output signal of the transient improvement circuit must be supplied to the luminance input circuit. When the CTI function is not required the two pins must be AC-coupled.
Video switches
The circuit has two CVBS inputs and an Super-Video Home System (S-VHS) input. The input can be chosen by the I
2
C-bus. The input selector also has a position in which
CVBS
EXT
is processed, unless there is a signal on the S-VHS input. When the input selector is in this position it switches to the S-VHS input if the S-VHS detector detects sync pulses on the S-VHS luminance input. The S-VHS detector output can be read by the I2C-bus. When the S-VHS option is not used the luminance input can be used as a second input for external CVBS signals. The choice is made via the CVS-bit (see Table 1).
The video switch circuit has two outputs which can be programmed in a different way. The input signal for the decoder is also available on the TXT output. Therefore this signal can be used to drive the teletext decoder and the SECAM add-on decoder. The signal on the PIP output can be chosen independent of the TXT output. If S-VHS is selected for one of the outputs the luminance and chrominance signals are added so that a CVBS signal is obtained again.
Colour decoder
The colour decoder contains an alignment-free crystal oscillator, a killer circuit and the colour difference demodulators. The 90° phase shift for the reference signal is made internally. The demodulation angle and gain ratio for the colour difference signals for PAL and NTSC are adapted to the standard.
The colour decoder is very flexible. Together with the SECAM decoder TDA8395 an automatic multistandard decoder can be designed.
Which standard the IC can decode depends on the external crystals. If a 4.4 MHz and a 3.5 MHz crystal are used PAL 4.4, NTSC 4.4, NTSC 3.5 and PAL 3.5 can be decoded. If two 3.5 MHz crystals are used PAL N and M can be decoded. If one crystal is connected only PAL/NTSC 4.4 or PAL/NTSC 3.5 can be decoded. The crystal frequency of the decoder is used to tune the line oscillator. Therefore the value of the crystal frequency must be given to the IC via the I
2
C-bus.

RGB output circuit and black-current stabilization
The colour-difference signals are matrixed with the luminance signal to obtain the RGB-signals. For the RGB-inputs linear amplifiers have been chosen so that the circuit is suited for signals coming from the SCART connector. The contrast and brightness control operate on internal and external signals.
The output signal has an amplitude of approximately 2 V black-to-white at nominal input signals and nominal settings of the controls.
The black current stabilization is realized by means of a feedback from the video output amplifiers to the RGB control circuit. The ‘black current’ of the 3 guns of the picture tube is internally measured and stabilized. The black level control is active during 4 lines at the end of the vertical blanking. During the first line the leakage current is measured and the following 3 lines the 3 guns are adjusted to the required level. The maximum acceptable leakage current is ±100 µA. The nominal value of the ‘black current’ is 10 µA. The ratio of the currents for the various guns automatically tracks with the white point adjustment so that the back-ground colour is the same as the adjusted white point.
The input impedance of the ‘black-current’ measuring pin is 15 k. Therefore the beam current during scan will cause the input voltage to exceed the supply voltage. The internal protection will start conducting so that the excessive current is bypassed.
When the TV receiver is switched-on the black current stabilization circuit is not active, the RGB outputs are blanked and beam current limiting input pin is short-circuited. Only during the measuring lines will the outputs supply a voltage of 5 V to the video output stage so that it can be detected if the picture tube is warming up. These pulses are switched-on after a waiting time of approximately 0.5 s. This ensures that the vertical deflection is activated so that the measuring pulses are not
visible on the screen. As soon as the current supplied to the measuring input exceeds a value of 190 µA the stabilization circuit is activated. After a waiting time of approximately 0.8 s the blanking and the beam current limiting input pin are released. The remaining switch-on behaviour of the picture is determined by the external time constant of the beam current limiting network.

C-BUS SPECIFICATION
Valid subaddresses: 00 to 13; subaddress FE is reserved for test purposes. Auto-increment mode is available for subaddresses.
Start-up procedure
Read the status bytes until POR = 0 and send all subaddress bytes. The horizontal output signal is switched-on when the oscillator is calibrated. It is possible to have the horizontal output signal available before calibration. Then the SFM bit must be set to logic 0.
Each time before the data in the IC is refreshed, the status bytes must be read. If POR = 1, the procedure mentioned above must be carried out to restart the IC.
When this procedure is not followed the horizontal frequency may be incorrect after power-up or after a power dip.
