General Description

The MAX9320B low-skew, 1-to-2 differential driver is

designed for clock and data distribution. The input is

reproduced at two differential outputs. The differential

input can be adapted to accept single-ended inputs by

applying an external reference voltage.

The MAX9320B features ultra-low propagation delay

(208ps), part-to-part skew (20ps), and output-to-output

skew (6ps) with 30mA maximum supply current, mak-

ing this device ideal for clock distribution. For interfac-

ing to differential PECL and LVPECL signals, this

device operates over a +3.0V to +5.5V supply range,

allowing high-performance clock or data distribution in

systems with a nominal 3.3V or 5V supply. For differen-

tial ECL and LVECL operation, this device operates

from a -3.0V to -5.5V supply.

The MAX9320B is offered in industry-standard 8-pin

TSSOP and SO packages.
