LC89610中文资料三洋数据手册PDF规格书

Overview

The LC89610 is a playback signal processing CMOS LSI that supports the mini-disk data format. Data that has been decoded by a CD decoder, an ACIRC decoder, or a CDROM decoder circuit is passed to a DRAM controller circuit and the LC89610 uses external DRAM to process shock proof. The shock proof processed data is passed to an audio data decoding LSI, the LC89602.
