DETAILED DESCRIPTION
The DS2118M Ultra3 LVD/SE SCSI terminator is both a low-voltage differential (LVD) and single-
ended (SE) terminator. The multimode operation enables the designer to implement LVD in current
products while allowing the end-user SE-backward compatibility with legacy devices. If the device is
connected in an LVD-only bus, the DS2118M will use LVD termination. If any SE devices are connected
to the bus, the DS2118M will use SE termination. This is accomplished automatically inside the part by
sensing the voltage on the SCSI bus DIFFSENS line.
For the LVD termination, the DS2118M integrates two current sources with nine precision resistor
strings. For the SE termination, one regulator and nine precision 110 resistors are used. Three
DS2118M terminators are needed for a wide SCSI bus.
