SY58020UMG General Description

The SY58020U is a 2.5V/3.3V precision, high-speed, fully differential 1:4 CML fanout buffer. Optimized to provide four identical output copies with less than 15ps of skew and less than 10psPP total jitter, the SY58020U can process clock signals as fast as 6GHz.The differential input includes Micrel's unique, 3-pin input termination architecture interfaces to differential LVPECL, LVDS, and CML 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 optimized to drive 400mV typical swing into 50Ω loads, with extremely fast rise/fall times guaranteed to be less than 60ps.The SY58020U 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 LVPECL outputs, consider the SY58021U or SY58022U 1:4 fanout buffer with 800mV and 400mV output swing, respectively. The SY58020U is part of Micrel's high-speed, Precision Edge? product line.
