Case #4: Input Clock Failure:
Switching from the
selected clock input stuck in an undetermined state
to a valid clock input (RPE-enabled).
If CLK1 fails to an undetermined state (e.g.,
amplitude falls below the 100mV (VIN) minimum
single-ended input limit, or 200mV differentially)
before the RPE MUX selects CLK2 (using the SEL
pin), the switchover to the valid clock CLK2 will
occur either following Case #2 or Case #3,
depending upon the last valid state at the CLK1.
If the selected input clock fails to a floating, static, or
extremely low signal swing, including 0mV, the FSI
function will eliminate any metastable condition and
guarantee a stable output signal. No ringing and no
undetermined state will occur at the output under
these conditions.
Please note that the FSI function will not prevent
duty cycle distortions or runt pulses in case of a
slowly deteriorating (but still toggling) input signal.
Due to the FSI function, the propagation delay will
depend upon rise and fall time of the input signal
and on its amplitude. Refer to “Typical Operating
Characteristics” for detailed information.
