LC895994 fiche technique
Ordering number : EN*5824
Preliminary
CMOS IC
LC895994
CD-R Encoder/Decoder LSI with
Built-in ATAPI (IDE) Interface
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
— Frequencies
Decoding: 17.2872 MHz
Encoding: 17.2872 MHz without Write Strategy
support
69.1488 MHz with Write Strategy
support
• IDE Transfer rate: 13.3 MB/s when using 16-bit data
path 80-ns DRAM chips
• Buffer RAM sizes between 1 and 32 megabits (using 16-
bit DRAMs)
• User control over sizes of CD main channel, C2 flag
areas in buffer RAM
• Built-in batch transfer function for transferring entire
CD main channel, C2 flag, or subcode area in a single
operation
• Built-in multiblock transfer function for transferring
multiple blocks in a single operation
