LC89585中文资料三洋数据手册PDF规格书

Overview

The LC89585 is an LSI that implements the digital processing required for CD-R recording in conformance with the orange book specifications. The LC89585 adds subcode data to record data processed by an A/D converter and the built-in DIR (digital audio interface receiver), FS decoder, and CD decoder circuits, and converts that data to CIRC (cross-interleave reed-solomon code) data. The LC89585 then performs EFM (eight-to-fourteen modulation encoding) conversion in real time.

Features

• A/D converter clock generation

• Built-in DIR (conforming to the IEC958 standard) and DIT (Digital audio interface transmitter)

• Built-in fader and muting circuits

• On-chip buffer RAM for encoder processing

• Automatic linking position processing function

• CCB CPU interface
