The SY58012U is a 2.5V/3.3V precision, high-speed, fully differential 1:2 LVPECL fanout buffer. Optimized to provide two identical output copies with less than 15ps of skew and less than 10ps(pk-pk) total jitter, the SY58012U can process clock signals as fast as 5GHz or 5Gbps data.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 100k LVPECL compatible, with extremely fast rise/fall times guaranteed to be less than 110ps.The SY58012U operates from a 2.5V ±5% supply or 3.3V ±10% supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). For applications that require faster rise/fall times, or greater bandwidth, consider the SY58013U 1:2 fanout buffer with 400mV output swing, or the SY58011 1:2 CML (400mV) fanout buffer. The SY58012U is part of Micrel's high-speed, Precision Edge® product line.
