Description

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-tofourteen modulation encoding) conversion in real time.
