SY58609U - Micrel Semiconductor

SY58609U CML 2:1 MUX

The SY58609U is a 2.5/3.3V, high-speed, fully differential CML 2:1 MUX capable of processing clock signals up to 2.5GHz and data patterns up to 4.25Gbps. The SY58609U is optimized to provide a buffered output of the selected input with less than 20ps of skew and less than 10pspp total jitter. The differential input includes Micrel’s unique, 3-pin input termi.
