FUNCTIONAL DESCRIPTION DEFLECTION Synchronization Separator synchronization separator based bottom synchronization pulses alignment internal reference voltage. external capacitor permits align syncro. pulses, external resistors determines detection threshold synchro pulses. frame synchronization pulses locked 32µs reference signal perfect interlacing.
shutting down, horizontal pulses inhibited 6.2V vertical output signal 10.5 lines width. permits drive sawtooth generator like TDA1771. video recognition function permits sent information video identification forces level voltage this pin. CHROMA

4.43MHz Phase Locked Loop oscillating frequency 4.43Mhz crystal oscillator controlled output voltage loop filter. phase detector will lock reference signal direct burst signal. phase shifter permits recover reference signal. flip-flop driven line pulses permits generate alternative signal. Control Color Killer direct burst signal demodulated with reference signal. demodulation result used both control killer functions. demodulation result always positive, killer capacitor charged signal identified (color ON). When demodulation result always negative, killer capacitor discharged, when voltage across capacitor reaches flip-flop inhibition level, alternance signal reversed, then reference signal phase with alternative burst killer capacitor charged again. case video signal, killer voltage maintained middle voltage below color ABSOLUTE MAXIMUM RATINGS

VIDEO luminance input controlled contrast control stage which range 20dB. luminance color difference signals added video matrix circuit obtain color signals. color signals sent switch which will drive outputs either internal signals external signals. With second threshold fast blanking input, possible blank outputs thus connect Screen Display signals directly outputs. inputs controlled 12dB range contrast control stage. black levels controlled thanks three external capacitors. avoid black level inserted signal differing from black level normal video signal, external clamped black level luminance signal. Therefore, coupling required inputs.
