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.
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 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
