LA7567GM Overview
ENN6803 Monolithic Linear IC LA7567GM TV and VCR VIF/SIF IF Signal-Processing Circuit with NTSC SPLIT Support 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.
