SY58022U - Micrel Semiconductor

SY58022U 5.5GHz 1:4 FANOUT BUFFER/ TRANSLATOR

The SY58022U is a 2.5V/3.3V precision, high-speed, fully differential 1:4 LVPECL fanout buffer. Optimized to provide four identical output copies with less than 15ps of skew and less than 10psPP total jitter, the SY58022U can process clock signals as fast as 5.5GHz. The differential input includes Micrel’s unique, 3-pin input termination architecture interfa.
