GENERAL DESCRIPTION
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.
