摘要:
100315
Low-Skew Quad Clock Driver
General Description
The 100315 contains four low skew differential drivers, de-
signed for generation of multiple, minimum skew differential
clocks from a single differential input. This device also has
the capability to select a secondary single-ended clock
source for use in lower frequency system level testing. The
100315 is a 300 Series redesign of the 100115 clock driver.
Features
n Low output to output skew (≤50 ps)
