    Precision LVDS 2:1 Multiplexer with 1:2
    Fanout and Internal Termination General Description
    The SY89474U is a 2.5V 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 325mV LVDS with fast rise/fall times guaranteed
    to be less than 150ps.
    The SY89474U operates from a 2.5V В±5% supply and is
    guaranteed over the full industrial temperature range of
    -40°C to +85°C. The SY89474U is part of Micrel’s highspeed, Precision Edge® product line. For multiple clock
    switchover solutions, please refer to the SY89840U–
    SY89845U family.
    All support documentation can be found on Micrel’s web
    site at: Functional Block Diagram В® Precision Edge Features Selects between two input channels and provides two
    copies of the selected input Guaranteed AC performance over temperature and
    supply voltage:
    -DC to 2.5Gbps data throughput ...
