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°C.


  • High Frequency >150 MHz
