SY58011U - Micrel Semiconductor

SY58011U 1:2 CML FANOUT BUFFER/TRANSLATOR

The SY58011U is a 2.5V/3.3V precision, high-speed, fully differential 1:2 CML fanout buffer. Optimized to provide two identical output copies with less than 15ps of skew and only 49fsRMS phase jitter, the SY58011U can process clock signals as fast as 7GHz or data patterns up to 10.7Gbps. The differential input includes Micrel’s unique, 3-pin input terminatio.
