CY23FS08 Input Switching Behavior with an External Mux
When an external mux is used with the need to have more that 2 inputs, do we have glitches passing from an input to another?
As the output derives from the DCXO, there will be no glitches on the output whether the input mux is internal or external, or even if the input reference fails completely. However, there will be a slight delay while the phase adjusts from the previous input to the new input, as seen in Figure 6 on page 5 of the CY23FS08 datasheet. This will not cause glitches, but will cause the phase/frequency to adjust for a short period.
