DESCRIPTION
The DS2117M Ultra2 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 DS2117M will use LVD termination. If any
SE devices are connected to the bus, the DS2117M 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 DS2117M integrates two
current sources with nine precision resistor strings. For
the SE termination, one regulator and nine precision
110 Ohm resistors are used. Three DS2117M termina-
tors are needed for a Wide SCSI bus.
