The user must take the PLL jitter into account in
the application (for example in serial communica-
tion or sampling of high frequency signals). The
PLL jitter is a periodic effect, which is integrated
over several CPU cycles. Therefore, the longer the
period of the application signal, the less it is im-
pacted by the PLL jitter.

frequencies of less than 125 kHz, the jitter is neg-
ligible.
