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 inputs with IC internal switching for easy design of multi-sound systems.
Additionally, these switches can also be used for video system sound trap switching.
The LA75665NV also includes a buzz canceller t...
