Connection Diagram


Description

The DS2120A Ultra3 LVD SCSI Terminator is a Low Voltage Differential (LVD) terminator. If the device is connected in an LVD-only bus, the DS2120A will use LVD termination. If any single-ended (SE) or high-voltage differential (HVD) devices are connected to the bus, the DS2120A will isolate itself from the SCSI bus. This is accomplished automatically inside the part by sensing the voltage on the SCSI bus DIFFSENS line.

For the LVD termination, the DS2120A integrates two current sources with nine precision resistor strings. Three DS2120A terminators are needed for a wide SCSI bus.
