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.

•Absolute maximum ratings (Ta = 25°C)
