SY58020U

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 10ps(pk-pk) 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 50 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 highspeed, Precision Edge™ product line. Data sheets and support documentation can be found on Micrel's web site at www.micrel.com.
