Ultra-SCSI Expander ASIC Improves Noise Immunity

The Ultra ASIC, an Ultra-SCSI expander chip, gives OEMs and RAID integrators access to SCSI speeds of up to 40 MB/s with improved noise immunity. The chip can be used to either extend the single-ended SCSI bus or convert it from single-ended to differential. As a bonus, the device acts as a SCSI isolator. Both SCSI buses are isolated, allowing users to connect or disconnect devices without shutting down the system.The device-independent ASIC supports Narrow and Wide SCSI, does not occupy a SCSI ID, and can support up to 16 SCSI devices. It's available in three different packages.
