MAXIM MAX9320, MAX9320A User Manual

For pricing delivery, and ordering information please contact Maxim/Dallas Direct! at

General Description

The MAX9320/MAX9320A are low-skew, 1-to-2 differen­tial drivers 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 MAX9320/MAX9320A feature ultra-low propagation
delay (208ps), part-to-part skew (20ps), and output-to­output 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 distrib­ution 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 double­sided board.

These devices are offered in space-saving 8-pin SOT23,
µMAX, and SO packages.
