VD1-OUT

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.

Note 1: The signal format for SYNC1-IN (pin 26) and SYNC2-IN (pin 24)

525P/60 Hz, 625P/50Hz, 750P/60 Hz, 1125I/60 Hz, 1125I/50 Hz, NTSC Double Scan (525I/120 Hz), PAL/SECAM Double Scan (625I/100 Hz)

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