SY58606U - Micrel Semiconductor

SY58606U 1:2 CML Fanout Buffer

The SY58606U is a 2.5/3.3V, high-speed, fully differential 1:2 CML fanout buffer optimized to provide two identical output copies with less than 15ps of skew and 100fsRMS of typical additive phase jitter. The SY58606U can process clock signals as fast as 3GHz or data patterns up to 4.25Gbps. The differential input includes Micrel’s unique, 3-pin input termin.
