LA75665NV Datasheet (Sanyo) - VIF/SIF IF Signal-Processing Circuit

LA75665NV, VIF/SIF IF Signal-Processing Circuit

Ordering number : ENN7162 Monolithic Linear IC LA75665NV VIF/SIF IF Signal-Processing Circuit with TV/VCR PAL and NTSC Multisound Support Overview The LA75665NV 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 input
