21. All timing figures defined with a capacitor of 2.2 nF at pin 19. The identification can be speeded up by lowering the

value of this capacitor, however this makes the circuit also less sensitive if the video signal is disturbed (airplane
flutter etc.). If the identification is only used as a sound mute a capacitor of 47 nF is recommended to improve the
sensitivity.
