Overview
The LC895994 is a CD-R LSI that provides a wide range
of functions including CD-ROM decoding (including
ECC) and encoding, subcode Q encoding (CRC addition)
and decoding, CD encoding, ATIP decoding and CLV
servo, and an IDE interface that includes the register
block.
Features
ECC and EDC correction/addition for the CD-ROM
data (during decoding and encoding)
ATIP decoding and CRC checking for both encoding
and decoding
CLV servo control using ATIP data during encoding
CIRC code insertion and EFM modulation during
encoding
Support for PCA random EFM output during encoding
Support for CD-ReWritable (CD-RW) Write Strategy
signal output
Access to buffer RAM from microcontroller via
LC895994
Built-in ATAPI (IDE) interface
Speeds of 12
× for decoding and 4× for encoding
