Status: In Production
The SY58022U 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 of skew and less than 10psPP total jitter, the SY58022U can process clock signals as fast as 5.5GHz.The differential input includes Micrel's unique, 3-pin input termination architecture interfaces to differential LVPECL, CML, and LVDS 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 400mV LVPECL compatible, with extremely fast rise/fall times guaranteed to be less than 80ps.The SY58022U 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 greater output swing or CML compatible outputs, consider the SY58021U 1:4 fanout buffer with LVPECL outputs, or the SY58020U 1:4 fanout buffer with 400mV CML outputs. The SY58022U is part of Micrel's high-speed, Precision Edge® product line.
