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 adoptin
