Figure A-3. Jitter Definitions
The relative deviation of t_nom is at its maximum for one clock period, and decreases towards zero for larger
number of clock periods (N).
Defining the jitter as:
J(N)
=

For N < 100, the following equation is a good fit for the maximum jitter:
J(N) = --j--1---

NOTE
On timers and serial modules a prescaler will eliminate the effect of the jitter
to a large extent.
