Connection Diagram


Description

The DS2121A LVD SCSI Terminator is a Low Voltage Differential (LVD) terminator. If the device is connected in an LVD-only bus, the DS2121A will use LVD termination. If any SE devices are connected to the bus, the DS2121A will disconnect from the bus. This is accomplished automatically inside the part by sensing the voltage on the SCSI bus DIFFSENS line.

For the LVD termination, the DS2121A integrates two current sources with nine precision resistor strings. Three DS2121A terminators are needed for a wide SCSI bus.
