Function
HD input pin.
Input a separated horizontal sync signal
(1.0 to 2.0 Vp-p) via a resister and a
coupling capacitor.
The polarity of the input signal is detected
and its leading edge becomes a timing
trigger.
VD input pin.
Input a separated vertical sync signal (1.0 to
2.0 Vp-p) via a resister and a coupling
capacitor.
The polarity of the input signal is detected
and its leading edge becomes a timing
trigger.
