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)
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.
Clock frequency: 33.8688 MHz
• Transfer rates: Up to 16.6 MB/s (when 32× IORDY
used), up to 33 MB/s when Ultra DMA used. These
values apply when 16-bit 45 ns EDO DRAM is used.
• 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.
