    Docket ↓
    4.25Gbps Precision, CML 2:1 MUX with
    Internal Termination and Fail Safe Input General Description
    The SY58609U is a 2.5/3.3V, high-speed, fully
    differential CML 2:1 MUX capable of processing clock
    signals up to 2.5GHz and data patterns up to 4.25Gbps.
    The SY58609U is optimized to provide a buffered output
    of the selected input with less than 20ps of skew and
    less than 10pspp total jitter.
    The differential input includes Micrel’s unique, 3-pin
    input termination architecture that interfaces to LVPECL,
    LVDS or CML differential signals, (AC-or DC-coupled)
    as small as 100mV (200mVpp) without any level-shifting
    or termination resistor networks in the signal path. For
    AC-coupled input interface applications, an integrated
    reference voltage (VREF-AC) is provided to bias the VT pin.
    The outputs are 400mV CML, with extremely fast
    rise/fall times guaranteed to be less than 90ps.
    The SY58609U operates from a 2.5V В±5% supply or
    3.3V В±10% supply and is guaranteed over the full
    industrial temperature range (–40°C to +85°C). For
    applications that require LVPECL or LVDS outputs,
    consider Micrel’s SY58610U and SY58611U, 2:1 MUX ...
