1:5/1:7 Clock Buffer

for Networking Applications

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.
