【应用笔记】PLL抖动的影响ST10F27x的C- CAN模块 AN2352 Application note 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. This docume……
