Input Signal/Output Signal

White 100％ = 1 Vp−p

or

DAC1 output pin.

8

In Test mode, outputs VD or

composite sync signal to

frequency counter.

20 DAC1 (V SYNC output)

To improve the driving ability, it

is possible to connect a

resister (minimum: 2 kΩ)

between this pin and GND.

200 Ω

However, when the resister is

added, the output DC voltage

is down.

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.
