The DS2120B Ultra3 LVD SCSI terminator is a low-voltage differential (LVD) terminator. If the device is connected in an LVD-only bus, the DS2120B uses LVD termination. If any single-ended (SE) or high-voltage differential (HVD) devices are connected to the bus, the DS2120B disconnects from the bus. This is accomplished inside the part automatically by sensing the voltage on the SCSI bus DIFFSENS line.
For the LVD termination, the DS2120B integrates two current sources with nine precision resistor strings. Three DS2120B terminators are needed for a wide SCSI bus.
