一、ECS展频晶振介绍

ECS晶振发展至今不管是生产工艺还是应用都已经非常成熟了，但是你真的了解过ECS晶振吗？从我们熟悉的有源晶振、无源晶振到到晶体、振荡器以及展频晶振，这些名称怎么来的？要了解这些问题还得从ECS晶振的本体——石英晶体讲起；（实际上作为振荡器不止有石英晶振，还有基于半导体的晶振以及陶瓷晶振。石英晶振因为发展时间长，技术相对成熟以及使用广，本文只围绕ECS石英晶振来讲。）

石英晶振的主要功能材料为水晶，即一种化学成分为二氧化硅（SiO2）的六角锥形结晶体。石英之所以成为谐振器的原材料，是由于它具有正（机械能→电能）、逆（电能→机械能）压电效应。如果沿石英晶片的电轴或机械轴施加压力使晶片产生形变，那么垂直于这些轴的两个表面则会产生电荷，这种现象称为正压电效应。如果在石英晶体两个表面施加电场，则晶片在电轴和机械轴方向将延伸或压缩，这种现象称为逆压电效应。基于这种特性，当石英晶振置于交变电场中，晶体的体积会发生周期性的压缩或拉伸，形成了晶体的机械振动。当交变电场的频率等于晶片的固有机械谐振频率时，晶片的机械振动幅度最大，产生共振现象。

当晶体通过基座、外壳、锌白铜、上盖等通过数十项工艺后就做出了我们的无源晶振。作为电子工程师都知道无源晶振需要起振还需要外围的起振电路，所以这种简单的晶振也叫晶体、无源晶振，优点主要为信号电平可变，低成本、低功耗等优势，应用场景十分丰富。

ECS晶振除了频率范围,工作电压,温度频差,温度范围这些参数,在选购防电磁干扰晶振时还需要选择扩展类型以及扩展百分比。

扩展类型分为向下和中心。向下扩展:是调制过程可以在标称频率的。中心扩展是50%向上和50%下降调制。扩展百分比是扩展频谱用百分比来衡量调制的大小。
