Low Voltage Differential LVD SCSI 9 Line Terminator

The UCC5641 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 UCC5641 allows for mini- mal bus loading for a maximum number of peripherals. With the UCC5641 the designer will be able to comply with the Fast-40 SPI-2 and Fast-80 SPI-3 specifications. The UCC5641 also provides a much-needed system migration path for ever improving SCSI system standards. This de- vice is available in the 24 pin TSSOP and 28 pin TSSOP for ease of lay- out use. The UCC5641 is not designed for use in single ended or high voltage dif- ferential systems. By Texas Instruments
