Low Skew 2:8 Differential Clock Driver
General Description
The 100310 is a low skew 8-bit differential clock driver
which is designed to select between two separate differen-
tial clock inputs. The low output to output skew (< 50 ps) is
maintained for either clock input. A LOW on the select pin
(SEL) selects CLKINA, CLKINA and a HIGH on the SEL
pin selects the CLKINB, CLKINB inputs.
The 100310 is ideal for those applications that need the
ability to freely select between two clocks, or to maintain
the ability to switch to an alternate or backup clock should a
problem arise with the primary clock source.
A V
BB
output is provided for single-ended operation.

Note 1:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2:
ESD testing conforms to MIL-STD-883, Method 3015.

Note 3:
The specified limits represent the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under “worst case” conditions.
