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 less than 10ps(pk-pk) total 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 termination architecture that interfaces to LVPECL, LVDS, or CML differential signals, (AC-coupled or DC-coupled) as small as 100mV without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an on-board output reference voltage (VREF-AC) is provided to bias the VT pin. The outputs are compatible with 400mV typical swing into 50 loads, with extremely fast rise/fall times guaranteed to be less than 60ps.
