SY56572XR Fanout Buffer

Microchip's SY56572XR is a fully differential, low voltage 1.2 V/1.8 V/2.5 V CML 4:1 MUX with input equalization and integrated 1:2 fanout buffer. The SY56572XR can process clock signals as fast as 4.5 GHz or data patterns up to 6.4 Gbps. The differential input includes Microchip’s unique 3-pin input termination architecture that interfaces to DC-coupled 2.5 V/3.3 V LVPECL, 1.2 V/1.8 V/2.5 V CML or LVDS differential signals. For AC-coupled input applications, an internal voltage reference is provided for input bias. Input voltages as small as 200 mV (400 mV pp) are applied before the 9-, 18-, or 27-inch FR4 transmission line.

The series operates from a 2.5 V ±5% core supply and a 1.2 V, 1.8 V or 2.5 V ±5% output supply and is guaranteed over the full industrial temperature range(-40°C to 85°C). The SY56572XR is part of Microchip’s high-speed Precision Edge^® product line.
