Monolithic Linear IC
LA7577N Super-split PLL-II VIF and SIF IF Signal Processor for TV/VTRs
Overview
The LA7577N is a high tone quality and high picture quality, video IF and sound IF IC. It employs split processing of the video IF signal and sound IF signal using SAW filters and a PLL detector. Further, the PLL detector incorporates a buzz canceler for Nyquist buzz interference suppression to achieve high tone quality.
