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 detection system with a buzz canceller in order
to provide the best sound quality possible.
