IMP2119

IMP2 1 1 9 DATA COMMUNICATIONS 9-Line ULTRA3 LVD/SE SCSI Terminator The IMP2119 is a multimode SCSI terminator that conforms to the SCSI Parallel Interconnect-2 (SPI-2) specification developed by the T10 standards committee for low voltage differential (LVD) termination. Multimode compatibility permits the use of legacy devices on the bus without hardware alterations. Automatic mode selection is achieved through voltage detection on the diffsense line. www.DataSheet4U.com Key Features N N N N N N N N N N N N Auto-selectable LVD or single-ended termination 3.0pF maximum disabled output capacitance Fast response, no external capacitors required Compatible with active negation drivers 15µA supply current in disconnect mode Logic command disconnects all termination lines DIFFSENSE line driver Ground driver integrated for single-ended operation Current limit and thermal protection Hot-swap compatible (single-ended) Compatible with SCSI, SPI-2, SPI-3, SPI-4 ULTRA160 and ULTRA320 Pin compatible with DS2119 The IMP2119 delivers the ultimate in SCSI bus performance while saving component cost and board area. Elimination of the external capacitors also mitigates the need for a lengthy capacitor selection process. The individual high bandwidth drivers also maximize channel separation and reduce channel to channel noise and cross talk. The high bandwidth architecture insures ULTRA3 performance. When the IMP2119 is enabled, the differential sense (DIFFSENSE) pin supplies a voltage betw...
