SYNC separator IC with AFC
BA7062F
The BA7062F separates the synchronization signals from a video signal and outputs the horizontal and vertical syn-
chronization signals (HD and VD), and the composite synchronization signal (Sync-out).
The HD and VD pulse widths are different.
Applications
•
TVs and VCRs
