    Precision LVPECL 1:10 Fanout with 2:1 Runt
    Pulse Eliminator MUX and Internal Termination General Description
    The SY89464U is a low jitter 1:10 LVPECL fanout
    buffer with a 2:1 differential input multiplexer (MUX)
    optimized for redundant source switchover
    applications. Unlike standard multiplexers, the
    SY89464U’s unique 2:1 Runt Pulse Eliminator
    (RPE) MUX prevents any short cycles or “runt”
    pulses during switchover. In addition, a unique FailSafe Input (FSI) protection prevents metastable
    output conditions when the selected input clock fails
    to a DC voltage (voltage between the pins of the
    differential input drops below 100mV).
    The differential input includes Micrel’s unique, 3-pin
    internal termination architecture that allows
    customers to interface to any differential signal (ACor DC-coupled) as small as 100mV (200mVPP)
    without any level shifting or termination resistor
    networks in the signal path. The outputs are 800mV,
    100K-compatible LVPECL with fast rise/fall times
    guaranteed to be less than 220ps.
    The SY89464U 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 ...
