CMOS LSI
LC89585
CD Encoder LSI for CD-R Systems
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.
