Input Signal/Output Signal

White 100％ = 1 Vp−p

or

22 VD1-OUT

8

VD output pin.

Open collector output.

VD1/VD2 input signal is output

from this pin without

synchronization.

200 Ω

22

Polarity is switched by BUS

write function.

(Note) When HD PHASE will

be changed, synchronized 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.
