MAXIM DS2125 handbook

Update: 30 September, 2023

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 110� resistors are used. Two DS2125 terminators are needed for a wide SCSI bus.
