The LX5107 is a nine-line active terminator
for the SCSI parallel bus. This SCSI stan-
dard recommends active termination at
both ends of the SCSI bus.
During disconnect mode, the LX5107
requires a meager 30μA of supply current
while offering only 3.0pF of output capaci-
tance. To enter this low-power mode, the
disconnect pin should be driven low
thereby disconnecting the terminating re-
sistors and placing the internal low drop-
out regulator into low-power mode. In
disconnect mode, each termination line
presents a high impedance to the SCSI bus
with the overall effect being to preserve
high signal integrity and yield subsequent
reliable, error free communications.
During normal operation, the LX5107
consumes only 600μA of current which is
the lowest enabled supply current of any
terminator available on the market today.
Linfinity's proprietary BiCMOS low drop-
out regulator architecture enables this
unique and very efficient operating char-
acteristic.
The LX5107 also offers a precisely
trimmed channel output current specified
to a 5% tolerance. The maximum value
of the output current is trimmed as closely
as possible to the SCSI standard maximum
specification to give the highest possible
noise margin for fast SCSI operation. In
addition, the LX5107 sinks up to 50mA of
current making it compatible with today's
fast active negation drivers.
The LX5107 is a superior, pin-for-pin
replacement for a variety of industry prod-
ucts such as the DS2107S and DS21S07A
