SY56020XR Low Voltage 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer 6.4Gbps with Equalization General Description The SY56020XR is a fully differential, low voltage Precision Edge 1.2V/1.8V/2.5V CML 1:4 Fanout Buffer with input equalization. The SY56020XR can process clock Features signals as fast as 4.5GHz or data patterns up to 1.2V/1.8V/2.5V CML 1:4 Fanout Bufer with EQ. 6.4Gbps. Guaranteed AC performance over temperature and The differential input includes Micrels unique 3-pin input voltage: termination architecture that interfaces to DC-coupled DC-to > 6.4Gbps throughput 2.5V/3.3V LVPECL, 1.2V/1.8V/2.5V CML or LVDS <300ps propagation delay (IN-to-Q) differential signals. For AC-coupled input applications, an internal voltage reference is provided for input bias. <15ps within-device skew ) are applied Input voltages as small as 200mV (400mV pp Ultra-low jitter design before the 9, 18 or 27-inch FR4 transmission line. The <0.8ps random jitter RMS outputs are CML. <10ps deterministic jitter PP The SY56020XR operates from a 2.5V 5% core supply High-speed CML outputs and a 1.2V, 1.8V or 2.5V 5% output supply and is 2.5V 5% , 1.8/1.2V 5% power supply operation guaranteed over the full industrial temperature range Industrial temperature range: 40C to +85C (40C to +85C). The SY56020XR is part of Micrels high-speed, Precision Edge product line.
