SYNC separator IC with AFC
BA7046 / BA7046F
The BA7046 and BA7046F separate the synchronization signals from a video signal and output the horizontal and
vertical synchronization signals (HD and VD), and the composite synchronization signal (Sync-out).
The HD and VD pulse phase difference is guaranteed.
•
Applications
TVs and VCRs
•
Features
1) Built-in AFC circuit.
2) HD and VD phase difference guaranteed.
3) Low power dissipation. (approx. 21mW)
4) Low external parts count.
5) 8-pin DIP / SOP package.
6) Horizontal free-run frequency does not require
adjustment.
