CD Encoder LSI for CD-R Systems
LC89585
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-tofourteen 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
