100311
Low Skew 1:9 Differential Clock Driver
General Description
The 100311 contains nine low skew differential drivers,
Features
■ Low output-to-output skew
designed for generation of multiple, minimum skew differ-
■ 2000V ESD protection
ential clocks from
a single differential input (CLKIN,
■ 1:9 low skew clock driver
■ Differential inputs and outputs
CLKIN). If a single-ended input is desired, the VBB 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 CLKn
■ Available to industrial grade temperature range
(PLCC package only)
outputs and a HIGH on all of the CLKn 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.
