Video input Y signal inputs. 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 switching between
signals input from Pins 23 and 25 and
from Pins 27 and 29.
Low (0 to 0.8 V) :
High (2 V to V
GND other than the 75
Video input chroma signal inputs.
Coupled by means of a capacitor within
the IC.
Inputting a signal of –0.3 V or less may
lead waveform distortion.
Control input for switching the output
signal format for Pin 19.
Low : Y signal
High : Composite
