LC895925
Signal Processing LSI for CD-R Drives
Preliminaly Overview
The LC895925 provides the following signal processing functions for CD-R drives: CD-ROM decoding/encoding (complete with ECC processing for the former), subcode decoding/encoding, CD encoding, ATIP decoding, CLV servo, and SCSI interface registers. * Buffer RAM sizes between 1 and 32 megabits (using 16bit 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 Notes: 1. Using a SCSI master clock of 20 MHz with speeds up to 8x. 2. Using a SCSI master clock of 17.2872 MHz with speeds up to 4x.
Features
* CD-ROM decoding/encoding complete with error detection and error correction * Subcode decoding/encoding complete with 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 * 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 LC895925 * Built-in SCSI interface * Speeds of 12x for decoding and 4x for encoding -- Frequencies Decoding: 17.2872 MHz Encoding: 17.2872 MHz without Write Strategy support 69.1488 MHz with Write Strategy support * Transfers speeds of 10 megabytes/s (synchronous) and 5 megabytes/s (asynchronous) with 16 80-ns DRAMs *1
