Functions
CD-ROM ECC function, subcode read function, SCSI
interface
Features
On-chip SCSI interface (with built-in SCAM selection
register)
Supports 8× playback - Using ×16 80-ns DRAMs
Supports 4× playback - Using ×16 80-ns DRAMs or ×8
70-ns DRAMs
Transfer rates: 10 MB/s (synchronous), 5 MB/s
(asynchronous) using ×16 80-ns DRAMs*1
Transfer rates: 8.467 MB/s (synchronous), 4.2336 MB/s
(asynchronous) using ×8 70-ns DRAMs*2
Supports the connection of up to 32 Mb of buffer RAM
(using DRAM)
The user can freely set the CD main channel, C2 flag,
and other areas in buffer RAM.
Batch transfer function (transfers the CD main channel
and C2 flag data in a single operation)
Multi-block transfer function (automatically transfers
multiple blocks in a single operation)
High-speed transfer mode supports a 10-MB/s
(synchronous) transfer rate using ×8 80-ns DRAMs
Subcode ECC function
Note: 1. For speeds up to 8× speed, use a SCSI master
clock frequency of 20 MHz.
Note: 2. For speeds up to 4× speed, use a SCSI master
clock frequency of 16.9344 MHz.
