SYNC2-IN
DAC1 (V SYNC output)
This IC doesn’t have the sync-separation circuit for non-standard signals like weak strength signal, ghost signal and so on.
Pin Name
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)
Input Y signal (Note 1) for sync
separation circuit.
Input via clamp capacitor.
DAC1 output pin.
In Test mode, it outputs VD or
composite sync signal to
frequency counter.
To improve the driving ability, it
is possible to connect a
resister (minimum: 2 kΩ)
between this pin and GND.
However, when the resister is
added, the output DC voltage
is down.
