LA75675M-S Overview
ENN6276B Monolithic Linear IC LA75675M-S VIF/SIF IF Signal-Processing Circuit that Supports NTSC Intercarrier for TV and VCR Products Overview The LA75675M-S is an NTSC intercarrier VIF/SIF IC that adopts a semi-adjustment-free structure. In particular, it uses VCO adjustment to make AFT adjustment unnecessary and thus simplifies the overall adjustment process. A PLL-based technique is adopted for FM detection.
