    Precision LVDS 1:10 Fanout with 2:1 Runt
    Pulse Eliminator MUX and Internal Termination General Description
    The SY89465U is a low-jitter, 1:10 LVDS fanout
    buffer with a 2:1 differential input multiplexer (MUX)
    optimized for redundant source switchover
    applications. Unlike standard multiplexers, the
    SY89465Us 2:1 Runt Pulse Eliminator (RPE) MUX
    prevents any short cycles or “runt” pulses during
    switchover. In addition, a unique Fail-Safe Input
    (FSI) 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, 3-pin internal
    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 LVDS-compatible with
    fast rise/fall times guaranteed to be less than 220ps.
    The SY89465U operates from a 2.5V ±5% supply
    and is guaranteed over the full industrial
    temperature range of –40°C to +85°C. The ...
