KKA8362ANS
Integrated PAL and PAL/NTSC TV processor
GENERAL DESCRIPTION
The KKA8362ANS is designed to be used in a multi-standard TV receiver and contains functional units for processing signals of intermediate frequency of audio and sound, vertical scanning and line synchronisation of colour signal in PAL/NTSC and RGB output signal. The KKA8362ANS is pin to pin compatible with TDA8362A, Philips and nearly identical to the TDA8362. The main difference between KKA8362ANS and TDA8362 is that KKA8362ANS contain a black-current stabilisation circuit. Because of the required input pin for the black-current stabilisation circuit the luminance peaking function has been omitted in the KKA8362ANS. All other function of the 2 IC's are identical. The pinning of the 2 IC's is slightly different, because the KKA8362ANS have a ground connection on each side. This adoption of the pinning has positive effects on the application of the IC. The KKA8362ANS is 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 tuner, a SECAM decoder a base-band delay line (KKA4661) and output stages for audio, video and horizontal and vertical deflection.

FUNCTIONAL DESCRIPTION
Video IF amplifier The IF amplifier contains 3 AC-coupled control stages with a total gain control range of greater than 60 dB and sensitivity 70 V. 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 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. 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 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. To overcome this problem a speed-up circuit has been included which detects whether the AGC detector is activated every frame period. The circuit contains a video identification circuit which is independent of the synchronisation circuit. Therefore search tuning is possible when the display section of the receiver is used as a monitor. 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. 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. Synchronisation circuit The sync separator is proceeded 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 synchronised. The line oscillator operates at twice the line frequency. 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 5.5 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 circuit. The filters are realised by circuits and are automatically tuned tuning frequency with the crystal decoder. bandpass and trap means of gyrator by comparing the frequency of the
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.

KKA8362ANS
Demodulation and array/matrix mode is switched depending on input signal standard. The circuit can co-operate with the SECAM add-on decoder KKA8395. The communication between the two ICs is achieved via pin 32. The KKA8362ANS supplies the reference signal (4.43 MHz) for the calibration system of the KKA8395, identification of the colour standard is via the same connection. RGB output circuit The colour difference signals are matrixed with the luminance signal to obtain the RGB signals. The contrast and brightness controls operate on internal and external signals. When applying to output 21 voltage of more then 4 V there may be possibility of immediate application of RGB-signals to RGB-outputs. Outputs signal amplitude at nominal settings and input conditions is 2 V from white to black. Presence of automatic stabilisation of black current enables to eliminate further settings of dark level during operation. This circuit is a backfeed loop, operates during four line periods, which precede the end of the blanking frame pulse and stabilises black current of each of RGBchannels in sequence and independently.
