Ultra320
Data transfers 320 megabytes per second, first defined in SPI-4 - Fast-160
SCSI SPI-4 (SCSI Parallel Interface)
16 bit SCSI packetized commands with Synchronous data transfer rates up to 320
megabytes per second. LVD (Low Voltage Differential) SCSI is required SCSI
SPI-4 for Fast-160DT. A new data transfer mode is required, with an 80 MHz free
running clock to eliminate ISI problems with the clock signal, P1 gating signal
is clocked with the free running clock for a valid transfer.
New:
- Paced data transfer - Packetized SCSI
- Free running clock (ACK, REQ and P1 for valid data)
- ISI (Intersymbol Interference) Compensation - Precomp drivers
and Adaptive Active Filter receivers
- SKEW Compensation
- Training pattern - for the adaptive active filters and the skew
compensation
- Expander communications
