    Precision Low-Power 8:1 MUX with Internal
    Termination and 1:2 LVPECL Fanout Buffer General Description
    The SY89859U is a low jitter, low-power, high-speed
    8:1 multiplexer with a 1:2 differential fanout buffer
    optimized for precision telecom and enterprise server
    distribution applications. The SY89859U distributes
    clock frequencies from DC to >2.5GHz, and data rates
    to 2.5Gbps guaranteed over temperature and voltage.
    The SY89859U 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
    level shifting or termination resistor networks in the
    signal path. The outputs are 800mV, 100K-compatible
    LVPECL with extremely fast rise/fall time guaranteed
    to be less than 180ps.
    The SY89859U features a patent-pending isolation
    design that significantly improves on channel-tochannel crosstalk-induced jitter performance.
    The SY89859U 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 SY89859U
