Connection Diagram

Description

The DS2120 Ultra3 LVD SCSI terminator is a low-voltage differential (LVD) terminator. If the device isconnected in an LVD-only bus, the DS2120 uses LVD termination. If any single-ended (SE) or high-voltage differential (HVD) devices are connected to the bus, the DS2120 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 DS2120 integrates two current sources with nine precision resistor strings. Three DS2120 terminators are needed for a wide SCSI bus.
