I
The input signal from CVIN pin and YIN
pin is selected by I
externally.
Capacitor connection for black peak hold
of the dynamic picture (black expansion).
Composite video signal input.
Input the 1Vp-p (100% white including
sync) CV signal via a capacitor. The
sync level of the input signal is
clamped to 3.8V.
In addition, this pin detects input video
signal HSYNC, and outputs the status
via the status register CVSYNC.
Connect a capacitor that determines the
DC transmission ratio to GND.
