LVDlink transceivers provide the inherent reliability of differential SCSI, and a long-term migration path to faster SCSI transfer rates. The LVDlink transceivers reduce the power needed to drive the SCSI bus, so that the I/O drivers can be integrated direc

In addition, TolerANT SCSI devices do not cause glitches on the SCSI bus at power-up or power-down. This protects other devices on the bus from data corruption. When it is used with the LVDlink transceivers, TolerANT technology provides excellent signal qu
