1:5/1:7 2.5V Clock Buffer for
Networking Applications
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 distribu-
tion. 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 pro-
duces five outputs on PI49FCT20802 and seven outputs on
PI49FCT20803. PI49FCT2080x is characterized for operation
from –40°C to 85°C.
