Video output chroma signal input.
Coupled by means of a capacitor within
the IC.
Inputting a signal of –0.3 V or less may
lead waveform distortion.
Chroma 75
Y 75
Control input used for switching the
signals that are input from Pins 11
(EVFYIN) and 13 (YIN).
Low (0 to 0.8 V) :
High (2 V to V
Y signal input for viewfinder.
Coupled by means of a capacitor ; in
order to keep clamp error to a
minimum, keep the input impedance as
low as possible.
Control input for power saver. When in
power saving mode, the Y and C 75
drivers stop operating. The output of
Pin 31 (YOUT) and Pin 5 (COUT) goes
to high impedance.
Low (0 to 0.8 V) : normal operation
