Case #2: Input Clock Failure: Switching from a
selected clock stuck HIGH to a valid clock (RPE-
enabled).
If CLK1 fails HIGH before the RPE MUX selects
CLK2 (using the SEL pin), the switchover will occur
in three stages.
Stage 1: The output will remain HIGH for a
limited number of pulses of CLK2.
Stage 2: The output will switch to LOW and then
remain LOW for a limited number of falling edges
of CLK2.
Stage 3: The output will follow CLK2.
Timing Diagram 2
Note: Output shows extended clock cycle during switchover. Pulse width for both high and low of this cycle will always be
greater than 50% of the CLK2 period.
