除了提供指定频率外,振荡器可能还必须满足更多需求,具体取决于应用的性质。例如,一些应用需要精确定义的频率,这对于需要通过无线或串行接口与其他设备进行通信的系统来说尤其重要。像这样的精度通常以百万分之几 (ppm) 来衡量。
低功耗在电池供电或手持设备中至关重要,尤其适用于 RTC,它始终处于活动状态,即使在待机和低功耗模式下也是如此。
最后,需要确定成本、外形尺寸和操作环境等因素.HX7011C0020.000000是一款为满足时钟源而设计的通信系统晶体振荡器,ECERA晶振

每个晶体振荡器都采用一种谐振或调谐电路,以及放大和反馈,以产生特定频率的输出。
可以在电感-电容 (LC) 或电阻-电容 (RC) 网络上创建调谐电路,这两种网络都是简单的组件,可以在很宽的范围内改变频率。然而,创建精确的 LC 或 RC振荡器需要使用昂贵的精密元件;即便如此,它们也并不总能满足大多数应用所需的最高精度和稳定性。
晶体谐振器由石英制成,其极高的物理稳定性使其成为谐振元件的首选。它被切割成两个平行的面,上面有金属触点。石英显示出压电效应,这意味着当置于压力下时,会在表面上产生电压。同样,施加的电压会导致晶体在剪切运动中改变形状。

此外,反馈使晶体以其自然谐振频率振荡,这取决于晶体的尺寸和切割方式。最常见的切割形式称为 AT,可以在很宽的频率范围内部署,并表现出良好的热稳定性。
凭借非常高的品质 (Q) 因子,石英晶体谐振器表现出高度准确和极其稳定的频率,这意味着它们可以用作非常精确、低成本振荡器的基础产品。
