SYNC separator IC with AFC
BA7071F
The BA7071F contains a video synchronization separation circuit, a vertical video synchronization separation circuit,
a horizontal oscillation circuit, and a phase comparator. It separates and outputs the horizontal and vertical synchro-
nization signals (HD and VD), and the composite synchronization signal (Sync-out) from input video or composite
synchronization signals. The phase difference between HD and VD is guaranteed for both the rising and falling
edges of VD.
•^Applications
TVs, VCRs and camcorders
•^Features
1) Built in AFC circuit.
2) HD and VD phase difference guaranteed.
3) Wide supply voltage range (3V to 7V).
4) Horizontal free-run frequency does not require ad-
justment.
5) Low external parts count.
6) SOP 8-pin package.
