石英振荡电路的组成与设计
石英振荡电路的形式很多,但基本电路只有两类:并联晶体振荡器和串联晶体振荡器。前者石英晶体是以并联谐振的形式出现,而后者则是以串联谐振的形式出现。石英振荡电路主要由IC、石英谐振器XTAL 、电阻、PCB 等组成,下面对各组成部分做简单说明:
1、IC:可根据实用的需要任意选用,如CMOS 反向器IC;专用振荡IC;大规模的数字IC 中自备石英振荡门。
2 、负载特性:振荡电路(除去CRYSTAL) ,具有一个负阻特性(用网络频谱分析仪) ,振荡电路负阻值(绝对值) 必须大于3 倍的CRTSTAL 电阻值( CRYS2TAL ESR/ RR) ,振荡电路才可以稳定的振荡。
3 、电容:可根据用户的需要选用片式或传统结构的产品,但是应注意选择适用于高频的、低损耗的,选用NP0 系列的温度系数产品。
电阻:在选择尺寸的同时需注意功耗的满足。
4 、PCB :注意能满足高频的使用场合和注意尽量降低线路的分布参数,大面积接地和一点式接地方案的采纳。有必要的时候应注意EMI 的防护。
5 、石英谐振器XTAL :频率大于1MHz 的谐振器应选用ATMODE ,可根据用户的需要选择合适的外形尺寸和封装的晶体。主要电性指标: FL 、ESR 的CLOCK需要选用FL 及公差,并按Cg/ Cd 值,计算而得CL =
(Cs :线路分布杂散电容)
