LC895299W规格书详情
Overview
The LC895299W and LC895299L are CD-ROM drive digital servo system ICs that integrate all signal processing functions after the RF head amplifier on a single chip.
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 then outputs that signal via parallel I/O to the system microprocessor.
• Performs unscrambling and deinterleaving operations to rearrange the demodulated EFM signal in the stipulated order.
• Detects and corrects error signals and processes flags (C1: 2 errors, C2: 4 errors)
• References the C1 flags and the C2 error check result to set the C2 flags and interpolates or mutes the signal depending on the C2 flags.
• Provides two types of muting: zero-cross muting and soft muting.
• Independent left and right channel digital attenuators (8-bit resolution) Provides two types of attenuation: direct attenuation and soft attenuation.
• 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
