BA7046

Multimedia ICs 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.
