Monolithic Linear IC

LA7566

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 multi-

detection 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 LA7566 also includes a buzz canceller that

suppresses Nyquist buzz to achieve improved audio

quality.
