Appendix A Electrical Characteristics
The relative deviation of t
number of clock periods (N).
Defining the jitter as:
For N < 1000, the following equation is a good fit for the maximum jitter:
This is very important to notice with respect to timers, serial modules where a prescaler will eliminate the
effect of the jitter to a large extent.
