石英晶体振荡器电路应用笔记
IC内部有一个反相放大器(相移约为180°)形成部分振荡器电路。外部电路由石英晶体、Cx1、Cx2和Rv组成ca的另一个相移180°，满足360(或0)的反馈要求使电路以石英晶体给出的频率振荡
Rout，Cout:振荡器IC的输出电阻/输出电容Rin，Cin:石英晶体振荡器IC的输入电阻/-电容(起始值CMOS: 1M / 3pF) 这些值应在制造商的IC数据手册中说明，但很少具体说明尽管它们对电路设计很重要。Rout可以通过上的电压降来计算已知的负载电阻器
石英晶体的fL标称频率石英晶体的R1 ESR(通常指定为上限) 石英晶体的C0静态电容(通常规定为上限)石英晶体的C1动态(运动)电容(很少指定)连接的CH1、CH2电容(约。0,8pF)，可以忽略不计，因为包括在C0石英晶体的CL标称负载电容石英晶体的L1动态电感(很少指定)这些值在石英晶体制造商的数据表中规定。确切的数值可以通过用网络分析仪分析一批石英晶体得到.

实施/布局: 布局需要特别注意:低电容短走线、对称布局， 没有过孔，附近没有“热”迹线。如果无法避免过孔，则应铺设过孔 对称地。 验证: 必须在原型PCB上验证石英晶体振荡器的正确功能， 因为寄生电容和电阻事先是未知的 必须根据石英的预期功能调整电阻器和电容器晶体振荡器。 必须使用有源低电容探头(< =2pF)进行测量，因为电容>10pF的普通探头会完全改变设置并呈现所有测量没用。如果没有低电容探头，可以使用小陶瓷电容器(1~2pF)可以暂时与探头串联使用测量。然而，给定频率下分频器比率的重新校准不可避免.
