This IC doesn’t have the sync-separation circuit for non-standard signals like weak strength signal, ghost signal and so on.
Pin Name
NTSC (525I/60 Hz), PAL/SECAM (625I/50 Hz), NTSC Double Scan (525I/120 Hz), PAL/SECAM Double Scan (625I/100 Hz), 525P/60 Hz, 750P/60 Hz,
1125I/60 Hz, 1125P/30 Hz
Input Y signal (Note 1) for sync
separation circuit.
Input via clamp capacitor.
Connect to GND.
VD output pin.
Open collector output.
VD1/VD2 input signals are
output from this pin without
synchronization.
Polarity is switched by BUS
write function.
(Note) When HD PHASE will
be changed, synchronized VD
width will change. Use the start
phase of VD.
