The LX5212 is a nine-line active terminator
for the SCSI parallel bus. This SCSI standard
recommends active termination at both ends
of the SCSI bus.
During disconnect mode, the LX5212 re-
quires a meager 500nA of supply current
while offering only 2.5pF of output capaci-
tance. To enter this low-power mode, the
disconnect pin can be left open (floating)
or driven high, thereby disconnecting the
terminating resistors and placing the internal
low dropout regulator into low-power
mode. In disconnect mode, each termina-
tion 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 communica-
tions.
During normal operation, the LX5212
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 dropout
regulator architecture enables this unique
and very efficient operating characteristic.
The LX5212 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. And
the LX5212 sinks up to 30mA of current,
making it compatible with today's fast active
negation drivers.
The LX5212 is a superior, pin-for-pin
replacement for a variety of industry prod-
ucts, such as the UC5614.
