www.DataSheet4U.com Ordering number : ENN*6495 CMOS IC LC898093 40× Playback/12× Write CD-R/RW Encoder/Decoder IC with Built-in ATAPI Interface Preliminary Functions CD-ROM decoder/encoder functions CD decoder/encoder functions Pit and wobble CLV servo CAV audio functions ATAPI interface (include the register block) Subcode encoder/decoder functions ATIP demodulator/ATIP decoder Write strategy function (CD-R/RW) From 1 to 64 Mbits of buffer RAM can be used. (16-bit data bus EDO DRAM) The user can freely set up the CD main channel, C2 flag, and subcode areas in buffer RAM. Batch transfer function (Function for transferring the CD main channel, C2 flag, subcode, and other data in a single operation) Multi-transfer function (Function for automatically transferring multiple block to the host in a single operation) CAV audio functions Supports Ultra DMA modes 0, 1, and 2. Features ECC and EDC correction/addition (decoding/encoding) for CD-ROM data. ECC error correction/addition (decoding/encoding) for subcode data Servo control implemented in a digital servo system (decoding/encoding) CLV servo control using ATIP data (encoding) ATIP decoding function and CRC check function (decoding/encoding) CIRC code generation and addition and EFM modulation (encoding) CAV audio functions Provides high-precision CD-R/RW write strategy signal output Built-in ATAPI interface (with Ultra DMA 33 support) Supports 40× decoding and 12× encoding.
