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 powersupply 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.
