100311 Low Skew 1:9 Differential Clock Driver

100311
Low Skew 1:9 Differential Clock Driver
General Description
The 100311 contains nine low skew differential drivers,
designed for generation of multiple, minimum skew differ-
ential clocks from a single differential input (CLKIN,
CLKIN). If a single-ended input is desired, the V
BB
output
pin may be used to drive the remaining input line. A HIGH
on the enable pin (EN) will force a LOW on all of the CLK
n
outputs and a HIGH on all of the CLK
n
output pins. The
100311 is ideal for distributing a signal throughout a system
without worrying about the original signal becoming too
corrupted by undesirable delays and skew.
