LA7578N IF Signal Processing (Super PLL-II VIF + SIF) Circuit

Ordering number: EN 4952 Monolithic Linear IC LA7578N IF Signal Processing (Super PLL-II VIF + SIF) Circuit for TVs and VCRs Overview The LA7578N is an intercarrier-type VIF + SIF IC that supports excellent sound quality and image quality. The pin assignment of the LA7578N is identical to that of the LA7577N, allowing the LA7577N to be used for split systems while the LA7578N is used for intercarrier systems. In addition, the LA7578N suppresses Nyquist buzz interference by using a PLL detecti.
