The DS2125 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 DS2125 uses LVD termination. If any SE devices are connected to
the bus, the DS2125 uses SE termination, which is accomplished automatically inside the part by
sensing the voltage on the SCSI bus DIFFSENS line.
For the LVD termination, the DS2125 integrates two current sources with 15 precision resistor strings. For the SE termination, one regulator and 15 precision 110Ω resistors are used. Two DS2125 terminators are needed for a wide SCSI bus.
