interface
Features
• On-chip SCSI interface (with built-in SCAM selection
• Supports 8 playback - Using 16 80-ns DRAMs
• Supports 4 playback - Using 16 80-ns DRAMs or 8
• Transfer rates: 10 MB/s (synchronous), 5 MB/s
• Transfer rates: 8.467 MB/s (synchronous), 4.2336 MB/s
• Supports the connection of up to 32 Mb of buffer RAM
• The user can freely set the CD main channel, C2 flag,
• Batch transfer function (transfers the CD main channel
• Multi-block transfer function (automatically transfers
• High-speed transfer mode supports a 10-MB/s
• Subcode ECC function
Note: 1. For speeds up to 8 speed, use a SCSI master
