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.
