Description

The UCC5646 is a twenty-seven line active terminator for low-voltage-differential (LVD) SCSI networks. This LVD SCSI-only design allows the user to reach peak bus performance, while reducing system cost. The device is designed as an active Y-terminator to improve the frequency response of the LVD SCSI Bus. Designed with a 2-pF (typical) channel capacitance, the UCC5646 allows for minimal bus loading for a maximum number of peripherals. With the UCC5646, the designer is able to comply with the Ultra2, Ultra3, and Ultra160 specifications. The UCC5646 also provides a much-needed system migration path for the ever improving SCSI system standards.

This device is available in the 64-pin low-profile QFP package for ease of layout use. Single-ended (SE) and high-voltage differential (HVD) SCSI drivers are not supported.
