产品描述

The UCC5640 is an active terminator for low voltage differential (LVD) SCSI networks. This LVD 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 bus. Designed with a 1.5pF channel capacitance, the UCC5640 allows for minimal bus loading for a maximum number of peripherals. With the UCC5640, the designer will be able to comply with the Fast-40 SPI-2, Fast-80 SPI-3 and Fast-160 SPI-4 specifications. The UCC5640 also provides a much needed system migration path for ever improving SCSI system standards. This device is available in the 24-pin TSSOP and 28-pin TSSOP for ease of layout use.

The UCC5640 is not designed for use in single ended (SE) or high voltage differential (HVD) systems.
