DESCRIPTION

KEY FEATURES

■ 6pF OUTPUT CAPACITANCE DURING

The LX5203 is a nine-line active terminator

for the SCSI parallel bus. This SCSI standard

recommends active termination at both ends

of the SCSI bus.

sumes only 600µA of current. Linfinity's

proprietary BiCMOS low dropout regulator

architecture enables oscillation-free opera-

tion with minimal output capacitance.

Linfinity recommends a minimum stabiliza-

tion capacitor value of 2.2µF.

The LX5203 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 LX5203 sinks

up to 150mA of current making it compatible

with today's fast active negation drivers.

The LX5203 is a superior, pin-for-pin re-

placement for a variety of industry products

such as the UC5603 and UC5613.

DISCONNECT

■ 60µA SUPPLY CURRENT IN DISCON-

NECT MODE

During disconnect mode, the LX5203 re-

quires a meager 60µA of supply current,

while offering only 6pF of output capaci-

tance. To enter this low-power mode, the

disconnect pin can be left open (floating) or

driven high, thereby disconnecting the ter-

minating resistors and placing the internal

low dropout 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.
