晶振电路负载参数匹配与测试
资料介绍
晶振电路用于为微控制器单元(MCU)提供精准的时间频率基准,合理地匹配晶振电路负载参数具有十分重要的意义。首先阐述了Pierce晶振电路的基本原理,然后结合一款应用于电动助力转向系统(EPS)中的微控制器单元所匹配的晶振电路,介绍了晶振电路关键负载参数如负载电容、限流电阻、负性阻抗以及晶振驱动功率的理论计算方法和测试匹配方法。
The crystal oscillator circuit is used to provide an accurate time and frequency reference for the microcontroller unit(MCU),and it is great significance to reasonably match the load parameters of the crystal oscillator circuit.Firstly the basic principles of the Pierce crystal oscillator circuit was explained.Then the theoretical calculation method and the test matching method of the crystal oscillator circuit key load parameters,such as load capacitance,negative impedance,current limiting resistor and crystal drive power were introduced by combining with a crystal oscillator circuit used in the micro-controller unit on the electric power steering(EPS).
