Input Signal/Output Signal
White 100％ = 1 V_p−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.
