1:2 Differential LVPECL/LVECL/HSTL
Clock and Data Drivers
General Description
Features
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.
♦ Improved Second Source of the MC10LVEP11
(MAX9320)
♦ +2.25V to +3.8V Differential HSTL/LVPECL
Operation
♦ -2.25V to -3.8V LVECL Operation
♦ Low 22mA (typ) Supply Current
♦ 20ps (typ) Part-to-Part Skew
♦ 6ps (typ) Output-to-Output Skew
♦ 208ps (typ) Propagation Delay
♦ Minimum 300mV Output at 3GHz
♦ Outputs Low for Open Input
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.
♦ ESD Protection >2kV (Human Body Model)
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.
♦ Available in Thermally Enhanced Exposed-Pad
SO Package
These devices are offered in space-saving 8-pin SOT23,
µMAX, and SO packages.
