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.

4) Horizontal free-run frequency does not require ad-

justment.

2) HD and VD phase difference guaranteed.

3) Wide supply voltage range (3V to 7V).

5) Low external parts count.

6) SOP 8-pin package.

Absolute maximum ratings (Ta = 25°C)
