Note 1: The signal format for SYNC1-IN (pin 26) and SYNC2-IN (pin 24)
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)
This IC doesn’t have the sync-separation circuit for non-standard signals like weak strength signal, ghost signal and so on.
