Development of VCR video/audio signal processing LSI chip

摘要

This paper describes the new multi-functional LSI for home VCRs, which incorporates, in addition to a video signal processor, a normal audio signal processor and REC/PB FM equalizer using a new process. A completely adjustment-free system is accomplished with both zener-zap and automatic adjustment circuit techniques. Other notable achievements are smaller chip size as well as shorter development lead time, due to our own new process and CAE method.
