SY56572XR Low Voltage 1.2V/1.8V/2.5V CML 4:1 MUX with 1:2 FANOUT 6.4Gbps with EQUALIZATION General Description The SY56572XR is a fully differential, low voltage Precision Edge 1.2V/1.8V/2.5V CML 4:1 Mux, with input equalization, Features and integrated 1:2 Fanout Buffer. The SY56572XR can process clock signals as fast as 4.5GHz or data patterns 1.2V/1.8V/2.5V CML 4:2 MUX with input equalization. up to 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 <360ps propagation delay (IN-to-Q) differential signals. For AC-coupled input applications, <15ps within-device skew an internal voltage reference is provided for input bias. Ultra-low jitter design ) are applied Input voltages as small as 200mV (400mV pp before the 9, 18 or 27-inch FR4 transmission line. <0.8ps random jitter RMS <10ps deterministic jitter The SY56572XR operates from a 2.5V 5% core supply PP 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).
