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 differential clocks from a single differential input (CLKIN, 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 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.

Features
s Low output-to-output skew s 2000V ESD protection s 1:9 low skew clock driver s Differential inputs and outputs s Available to industrial grade temperature range (PLCC package only)
