TEST REPORT:
5208TR
The LX5208 is an eighteen-line active termi-
nator for the SCSI parallel bus. This SCSI
standard recommends active termination at
both ends of the SCSI bus.
During disconnect mode, the LX5208 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 LX5208 con-
sumes only 800μA of current, which is the
lowest enabled supply current of any termi-
nator available on the market today.
Linfinity's proprietary BiCMOS low dropout
regulator architecture enables this unique
and very efficient operating characteristic.
The LX5208 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 LX5208 sinks
up to 200mA of current making it compatible
with today's fast active negation drivers.
The LX5208 is a superior, pin-for-pin re-
placement for a variety of industry products
such as the UC5601, UC5602, UC5608, and
UC5609.
