General Description

The MAX9320/MAX9320A are low-skew, 1-to-2 differen-

tial drivers designed for clock and data distribution. The

input is reproduced at two differential outputs. The dif-

ferential input can be adapted to accept single-ended

inputs by applying an external reference voltage.

The MAX9320/MAX9320A feature ultra-low propagation

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

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

making these devices ideal for clock distribution. For

interfacing to differential HSTL and LVPECL signals,

these devices operate over a +2.25V to +3.8V supply

range, allowing high-performance clock or data distrib-

ution in systems with a nominal +2.5V or +3.3V supply.

For differential LVECL operation, these devices operate

from a -2.25V to -3.8V supply.

The pinout is the only difference between the MAX9320

and MAX9320A. Multiple pinouts are provided to simplify

routing across a backplane to either side of a double-

sided board.

These devices are offered in space-saving 8-pin SOT23*

and industry-standard TSSOP* and SO packages.
