    SY89841U
    Precision LVDS Runt Pulse
    Eliminator 2:1 Multiplexer General Description
    The SY89841U is a low jitter LVDS, 2:1 input
    multiplexer (MUX) optimized for redundant source
    switchover applications. Unlike standard
    multiplexers, the SY89841U unique 2:1 Runt Pulse
    Eliminator (RPE) MUX prevents any short cycles or
    “runt” pulses during switchover. In addition, a unique
    Fail-safe Input protection prevents metastable
    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
    input termination architecture that allows customers
    to interface to any differential signal (AC-or DCcoupled) as small as 100mV (200mVpp) without any
    level shifting or termination resistor networks in the
    signal path. The outputs are 350mV, LVDS with fast
    rise/fall times guaranteed to be less than 150ps.
    The SY89841U operates from a 2.5V ±5% supply
    and is guaranteed over the full industrial
    temperature range of –40°C to +85°C. The
    SY89841U is part of Micrel’s high-speed, Precision ...
