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