The oscillator drift is related to the picture carrier frequency, at external temperature-compensated LC circuit.
1.07) = 20 log (4.43 MHz component/1.07 MHz component); (1.07) value related to black-white signal
input signal conditions:
picture carrier = 0 dB, colour carrier = –6 dB, sound carrier = –24 dB
Without external control at Pin 13 the IC automatically operates in mode 1:
negative modulated video-IF signals and FM/NICAM sound signals.
Without control voltage at Pin 19 falling AFC curve is automatically selected.
With open circuit at Pin 14 the L’ switch is not active.
