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.
