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 will be
impacted by the PLL jitter.
