DESCRIPTION

KEY FEATURES

■ 6pF OUTPUT CAPACITANCE DURING

The LX5202 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.

sumes only 800µA of current, which is the

lowest enabled supply current of any termi-

DISCONNECT

■ 60µA SUPPLY CURRENT IN DISCON-

nator available on the market today.

Linfinity's proprietary BiCMOS low dropout

regulator architecture enables this unique

and very efficient operating characteristic.

The LX5202 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 LX5202 sinks

up to 200mA of current making it compatible

with today's fast active negation drivers.

The LX5202 is a superior, pin-for-pin re-

placement for a variety of industry products

such as the UC5601 and UC5602.

NECT MODE

During disconnect mode, the LX5202 re-

quires a meager 60µA of supply current while

offering only 6pF of output capacitance. To

enter this low-power mode, the disconnect

pin can be left open (floating) or driven high,

thereby disconnecting the terminating resis-

tors 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.
