LA75665NM VIF/SIF IF Signal-Processing Circuit

Ordering number : ENN 6954 Monolithic Linear IC LA75665NM VIF/SIF IF Signal-Processing Circuit with TV/VCR PAL and NTSC Multisound Support Preliminary Overview The LA75665NM 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 .
