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.
