Description
The PI49FCT380x is a 3.3V compatible, high-speed, low-noise
non-inverting clock buffer. The key goal in designing the
PI6C380x is to target networking applications that require low-
skew, low-jitter, and high-frequency clock distribution. Providing
output-to-output skew as low as 250ps, the PI49FCT380x 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.
