TEST REPORT:
5204TR
The LX5204 is a nine-line active terminator
for the SCSI parallel bus. This SCSI standard
recommends active termination at both
ends of the SCSI bus. The LX5204 has the
added features of hot swappability, fully
complying with the SCSI hot swap speci-
fication.
During disconnect mode, the LX5204 re-
quires a meager 60μA of supply current while
offering only 3.5pF of output capacitance.
To enter this low-power mode, the discon-
nect 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 discon-
nect 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 LX5204
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 LX5204 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 LX5204 sinks up to 150mA of current,
making it compatible with today's fast
active negation drivers.
The LX5204 is a superior, pin-for-pin
replacement for a variety of industry prod-
ucts such as the UC5603 and UC5613.
