美国艾博康ABRACON晶振结合内置电路石英的适当匹配ABS07-120-32.768KHZ-T
如今,大多数电子电路都基于时钟逻辑(包括微处理器、微控制器、FPGAs和CPLDs),需要一个时钟源.根据频率精度要求,有些采用谐振器,有些则使用现成的石英晶体结合内置谐振器电路；嵌入在大多数微控制器和微处理器.
Abracon Crystal晶振大多数(如果不是全部)嵌入式解决方案使用Pierce谐振器配置,集成为SOC(片上系统)的一部分.明显的事实与独立谐振器相比,优点包括成本、尺寸和功率；虽然关键的限制是石英的适当匹配内置皮尔斯谐振器的晶振美国艾博康ABRACON晶振,ABS07-120-32.768KHZ-T
从晶体来看,环路电容主要影响整体谐振器环路电容.该有效环路电容决定了谐振器环路相对于所需的谐振距离共振频率.然而,整体的长期表现贴片晶振谐振器环路受以下因素影响:这些环路电容的无功阻抗(Xc)逆变器放大器的跨导(gm)限流电阻(Rs)是否存在美国艾博康ABRACON晶振,ABS07-120-32.768KHZ-T
