LC895994
CD-R Encoder/Decoder LSI with
Built-in ATAPI (IDE) Interface
Preliminary
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.
