PI49FCT20802/
PI49FCT20803
1:5/1:7 2.5V Clock Buffer for
Networking Applications
Description
Features
• HighFrequency>150MHz
The PI49FCT2080x is 2.5V, high-speed, low noise, non-inverting
clock buffer. It is designed to target networking applications that
requirelow-skew,low-jitter,andhigh-frequencyclockdistribution.
It provides output-to-output skew as low as 150ps, and is an ideal
clockdistributiondeviceforsynchronoussystems. PI49FCT2080x
is a clock buffer from a single input that produces five outputs
on PI49FCT20802 and seven outputs on PI49FCT20803.
PI49FCT2080xischaracterizedforoperationfrom–40°Cto85°C.
