SYNC1-IN

Inputs Y signal (Note 1) for

sync separation circuit.

Input via clamp capacitor.

White 100％

or

VD1-OUT

VD output pin.

Open collector output.

VD1/VD2 input signal is 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.

Note 1: The signal format for SYNC1-IN (pin 21) and SYNC2-IN (pin 19)

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

This IC doesn’t have the sync-separation circuit for non-standard signals like weak strength signal, ghost signal and so on.
