Networking Applications
PI49FCT20802/
PI49FCT20803
Description
The PI49FCT2080x is 2.5V, high-speed, low noise, non-inverting
clock buffer. It is designed to target networking applications that
require low-skew, low-jitter, and high-frequency clock distribution.
It provides output-to-output skew as low as 150ps, and is an ideal
clock distribution device for synchronous systems. PI49FCT2080x
is a clock buffer from a single input that produces five outputs
on PI49FCT20802 and seven outputs on PI49FCT20803.
PI49FCT2080x is characterized for operation from –40
°
C to 85
