SY58021U Description
The SY58021U 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 output skew and only 70 fsRMS phase jitter, the SY58021U can process clock signals as fast as 4GHz. The differential input includes Micrel’s unique, 3-pin input termination architecture interfaces to differential LVPECL, CML, and LVDS signals (AC- or...
