Overview

The LA7567GM is an NTSC SPLIT support VIF/SIF IF

IC that adopts a semi-adjustment-free system. The VIF

block adopts a technique that makes AFT adjustment

unnecessary by adjusting the VCO, thus simplifying the

adjustment steps in the manufacturing process. PLL

detection is adopted in the FM detector. A 5-V power-

supply voltage is used to match that used in most

multimedia systems. In addition, this IC also includes a

buzz canceller to suppress Nyquist buzz and provide high

audio quality.
