PLL jitter effects on C-CAN modules of the ST10F27x

Introduction
PLL (Phase Locked Loop) is increasingly used in microcontrollers to achieve higher internal
clock frequencies. This improves performance while reducing overall noise. One drawback
in the use of PLL circuits is that they create a small but still measurable level of transient
phase shifts, or jitter. The aim of this note is to describe the effects of PLL jitter on the C-
CAN modules present in the devices of the family ST10F27x.
