PI49FCT20802/PI49FCT20803 1:5/1:7 2.5V Clock Buffer for Networking Applications Features Description High Frequency >150 MHz e PTh I49FCT2080x is 2.5V, high-speed, low noise, non-inverting clock buffer. It is designed to target networking applications that High-speed, low-noise, non-inverting clock buffer require low-skew, low-jitter, and high-frequency clock distribu- PI49FCT20802 is a 1:5 buffer tion. It provides output-to-output skew as low as 150ps, and PI49FCT20803 is a 1:7 buffer is an ideal clock distribution device for synchronous systems. Low skew < 150ps PI49FCT2080x is a clock buffer from a single input that pro- Low duty cycle distortion < 300ps duces five outputs on PI49FCT20802 and seven outputs on PI49FCT20803. PI49FCT2080x is characterized for operation Low propagation delay < 3.5ns from 40C to 85C.
