CD-R Encoder/Decoder IC with Built-in SCSI Interface
Overview
The LC895926 is a CD-R IC that provides a wide range of
functions including CD-ROM decoding (including ECC)
and encoding, subcode encoding and decoding, CD
encoding, ATIP decoding and CLV servo, and a SCSI
interface that includes the register block.
Features
• ECC and EDC correction/addition for CD-ROM data
(during decoding and encoding)
• Subcode decoding/encoding complete with error
detection and error correction
• 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
• Access to buffer RAM from microcontroller via
LC895926
• Built-in SCSI interface
• Speeds of 24× for decoding and 12× for encoding
• Transfers speeds of 10 megabytes/s (synchronous) and 5
megabytes/s (asynchronous) with 16-bit 50-ns EDO-
DRAMs
• Buffer RAM sizes between 1 and 32 megabits (using 16-
bit EDO-DRAMs)
• User control over sizes of CD main channel, C2 flag,
and subcode 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.
• Automatic sequencing of encoding and decoding
processing for a reduced processing load on the system
microcontroller.
