LA75665NM Datasheet (Sanyo) - VIF/SIF IF Signal-Processing Circuit

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.
