SY56020XR

The SY56020XR is a fully differential, low voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with input equalization. The SY56020XR can process clock signals as fast as 4.5GHz or data patterns up to 6.4Gbps.The differential input includes Micrel's unique 3-pin input termination architecture that interfaces to DC-coupled 2.5V/3.3V LVPECL, 1.2V/1.8V/2.5V CML or LVDS differential signals. For AC-coupled input applications, an internal voltage reference is provided for input bias. Input voltages as small as 200mV (400mVpp) are applied before the 9, 18, or 27-inch FR4 transmission line. The outputs are CML.The SY56020XR operates from a 2.5V ±5% core supply and a 1.2V, 1.8V or 2.5V ±5% output supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY56020XR is part of Micrel's high-speed, Precision Edge® product line.
