LA7566, VIF/SIF IF Signal-Processing Circuit

Ordering number : EN5764 Monolithic Linear IC LA7566 VIF/SIF IF Signal-Processing Circuit with TV/VCR PAL and NTSC Multisound Support Overview The LA7566 is a VIF/SIF IC that supports PAL and NTSC multisound and that adopts a semi-adjustment-free system.

To simplify adjustment, the VIF block adopts a technique in which AFT adjustment is no longer required by VCO adjustment.

The SIF block supports audio multidetection by adopting a PLL detection technique.

The SIF block provides 4 inputs with
