Description
The PI49FCT20807, a 2.5V compatible, high-speed, low-noise 1-10
non-inverting clock buffer, is designed to target networking appli-
cations that require low-skew, low-jitter, and high-frequency clock
distribution. Providing output-to-output skew as low as 150ps, the
PI49FCT20807 is an ideal clock distribution device for synchronous
systems. Designing synchronous networking systems requires a
tight level of skew from a large number of outputs.
