LC895299W

Ordering number : ENN6249A CMOS IC LC895299W, 895299L 48× Speed ATAPI (IDE) CD-ROM Decoder with On-Chip Digital Servo System Overview The LC895299W and LC895299L are CD-ROM drive digital servo system ICs that integrate all signalprocessing functions after the RF head amplifier on a single chip. Bilingual support Built-in digital audio interface (supports both CLV and CAV) Built-in digital deemphasis Built-in 8× oversampling digital filters Built-in D/A converters CD-ROM Decoder and ATAPI (IDE) Interface Block Built-in ATAPI (IDE) interface The user can freely set the CD main channel, C2 flag, and subcode areas in internal DRAM. Batch transfer function (Function for transferring the CD main channel, C2 flag, or subcode data in a single operation.) Multiple transfer function (Function for transferring multiple blocks automatically in a single operation.) CAV audio functions Intelligent functions (auto buffering, auto decoding, and CD-R functions) Subcode P to W buffering function (No ECC) and CD-TEXT support Supports Ultra DMA MODE2, MODE1, and MODE0 Built in 1-Mbit DRAM Functions Built-in digital servo and ATAPI (IDE) CD-ROM, CD-DSP, CAV audio, and1-Mbit DRAM functions Features CD-DSP Block Supports full CAV operation at 48× speed Assures stable data readout by performing frame sync signal detection, protection, and interpolation. Demodulates the EFM signal to produce 8-bit symbol data. Applies a CRC check to the subcode Q signal and...
