■ Overview

MN82832 is a system LSI which incorporates processing necessary for high-quality televisions in a one chipconfiguration.

High-efficiency 3-dimensions Y/C separation and color demodulation corresponding to an NTSC/PAL system, plus various functions of the digital YUV output are built in. It is most suitable as a television use LSI providing high-quality processing and multi-processing.
