1:10 Differential LVPECL/LVECL/HSTL
Clock and Data Drivers
General Description
The MAX9311/MAX9313 are low-skew, 1-to-10 differen-
tial drivers designed for clock and data distribution.
These devices allow selection between two inputs. The
selected input is reproduced at 10 differential outputs.
The differential inputs can be adapted to accept single-
ended inputs by connecting the on-chip V
BB
supply to
one input as a reference voltage.
The MAX9311/MAX9313 feature low part-to-part skew
(30ps) and output-to-output skew (12ps), making them
ideal for clock and data distribution across a backplane
or a board. 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 MAX9311 features an on-chip V
BB
reference output
of 1.425V below the positive supply voltage. The
MAX9313 offers an on-chip V
BB
reference output of
1.32V below the positive supply voltage.
Both devices are offered in space-saving, 32-pin 5mm
鉁?/div>
5mm TQFP, 5mm x 5mm QFN, and industry-standard
32-pin 7mm x 7mm LQFP packages.
