    Precision LVPECL 2:1 Multiplexer with 1:2
    Fanout and Internal Termination General Description
    The SY89473U is a 2.5V/3.3V precision, high-speed 2:1
    differential MUX capable of processing clocks up to
    2.5GHz and data up to 2.5Gbps.
    The differential input includes Micrel’s unique, 3-pin
    input termination architecture that directly interfaces to
    any differential signal (AC-or DC-coupled) as small as
    100mV (200mVPP) without any level shifting or
    termination resistor networks in the signal path. The
    output is 800mV, 100K-compatible, LVPECL with fast
    rise/fall times guaranteed to be less than 190ps.
    The SY89473U operates from a 2.5V В±5% or 3.3V
    В±10% supply and is guaranteed over the full industrial
    temperature range of –40°C to +85°C. The SY89473U is
    part of Micrel’s high-speed, Precision Edge® product
    line. For multiple-clock switchover solutions, please refer
    to the SY89840–SY89843U family.
