SY58604U - Micrel Semiconductor

SY58604U LVPECL Buffer

The SY58604U is a 2.5/3.3V, high-speed, fully differential LVPECL buffer optimized to provide only 108fsRMS phase jitter. The SY58604U can process clock signals as fast as 2.5GHz or data patterns up to 3.2Gbps. The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (A.
