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 (H^Dand VD), and the composite synchronization signal (Sync-out).

The H^Dand VD pulse phase difference is guaranteed.

Applications

•

TVs and VCRs

Features

1) Built-in AFC circuit.

•

4) Low external parts count.

2) H^Dand VD phase difference guaranteed.

3) Low power dissipation. (approx. 21mW)

5) 8-pin DIP / SOP package.

6) Horizontal free-run frequency does not require

adjustment.

Absolute maximum ratings (Ta = 25°C)
