SY58031U - Micrel Semiconductor

SY58031U Ultra-precision 1:8 Fanout Buffer

The SY58031U is a 2.5V/3.3V precision, high-speed, fully differential CML 1:8 fanout buffer. The SY58031U is optimized to provide eight identical output copies with less than 20ps of skew and only 75fsRMS phase jitter. It can process clock signals as fast as 6GHz. The differential input includes Micrel’s unique, 3-pin input termination architecture that allo.
