SCSI Interface
The SCSI interface includes these features:
•
Performs wide, Ultra160 SCSI synchronous data transfers as fast as
160 Mbytes/s using Double Transition (DT) clocking
•
Supports Cyclic Redundancy Check (CRC) checking and generation
in DT phases
•
Protects nondata phases with Asynchronous Information
Protection (AIP)
•
Automatically enables LVD or SE termination
•
Contains external 68-pin High Density (HD) and internal 68-pin HD
latching connectors
•
Provides SCSI termination power (TERMPWR) source with
autoresetting circuit protection device
•
Supports Basic (level 1), Enhanced (level 2), and Margined (level 3)
Domain Validation
•
Includes integrated LVDlink™ universal transceivers:
–
Supports 16-bit SE and LVD signals
–
Allows greater device connectivity and longer cable length
–
LVDlink transceivers save the cost of external differential
transceivers
–
Supports a long-term performance migration path
