GENERAL DESCRIPTION The DS2120 Ultra3 LVD SCSI terminator is a low-voltage differential (LVD) terminator. If the device is connected in an LVD-only bus, the DS2120 uses LVD termination. If any single-ended (SE) or high- voltage differential (HVD) devices are connected ...

During thermal shutdown, the termination pins are isolated from the SCSI bus and VREF becomes high impedance. The DIFFSENS driver is shut down during either of these two events. The DIFF_CAP receiver is disabled and the LVD goes low, indicating ...
