    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
    1.2V/1.8V/2.5V CML 4:1 Mux, with input equalization,
    and integrated 1:2 Fanout Buffer. The SY56572XR 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 SY56572XR operates from a 2.5V В±5% core supply
    and a 1.2V, 1.8V or 2.5V В±5% output supply and is
    guaranteed over the full industrial temperature range
    (–40°C to +85°C). The SY56572XR is part of Micrel’s
    high-speed, Precision Edge product line.
