LX5251CPW

9线多模SCSI终结者 9-Line Multimode SCSI Terminator

DESCRIPTION

The LX5251 is a multimode SCSI terminator that is compatible with the SCSI SPI-2 Ultra2, SCSI SPI-3 Ultra3 or Ultra160, and SCSI SPI-4 Ultra320 specifications developed by the T10 standards committee for low voltage

differential LVD termination, while providing backwards compatibility to the SCSI, SCSI-2, and SPI single-ended

specifications. 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.
