有源晶体振荡器环路在振荡器频率下具有低输入阻抗，但在谐振频率范围之外具有高输入阻抗特性。

当在其附近施加电场时，这种高阻抗特性很容易受到EMI的影响。较新的技术已将振荡器信号电平限制在 <1V，使其更容易受到影响。

为了强调保持低杂散 PCB 电容的重要性，突出显示了计算中的 Cs。晶体的CL越低，PCB 杂散电容对设计的影响就越大。伊西斯推出的ECS-.327-12.5-34B-TR这是一款微型,最具成本效益的贴片晶体

负载电容器 C1 / C2 的接地连接应尽可能短，以避免与其他电路产生接地电流。很多时候 XTAL IN 和 XTAL OUT 引脚在处理器上是相邻的。寄生电容可能是一个问题，因此走线应尽可能远离，同时保持尽可能短。

看到的典型电容可能是：

– XTAL IN 接地：1pF

– XTAL OUT 对地：2pF

– XTAL IN 到 XTAL OUT：0.5pF

大多数常见的水晶类型都有接缝密封的外壳，其中外壳盖与接地引脚电连接。对于这种类型的封装，建议将引脚接地以降低来自盖子的 EMI 的可能性。应该注意的是，接缝密封包装提供了更好的性能。另一种密封方法是玻璃密封贴片石英晶体，由于这个过程，盖子与接地引脚隔离。对于这种类型的封装，不建议将晶振上的接地引脚接地。伊西斯推出的ECS-.327-12.5-34B-TR这是一款微型,最具成本效益的贴片晶体

电磁兼容性 (EMC)

电磁兼容性是电气元件、设备和系统在其环境中按设计运行的能力。这是通过限制电磁能的无意产生、传播和接收来实现的。这些不需要的噪声源称为电磁干扰 (EMI)。EMC 的目标是不同设备在共同的电磁环境中正确运行。

地平面

当与模拟或数字电路以及混合组件一起使用时，接地层非常有效。接地连接是根据需要进行的，而不是在整个布局中统一进行。

接地平面不是通过简单地用铜填充所有空白空间并将其连接到地面来创建的。它的功能是允许返回电流流动，理想的布局应该对它有最小的中断。因此，使用多层板。整个统一层可以专用于地，一个用于电源，另一个用于信号传输。这增强了层间电容的分布。它还具有在高频时电源和地之间的低阻抗的额外好处。

单个孔对接地层没有影响，但大插槽可以。当接地平面被其他走线或孔中断时，正常的低电感电流会绕过障碍物，从而有效地增加电感。

美国ECS晶振只有在不跨越高 di/dt 流线的情况下才能容忍中断。承载高开关电流或快速逻辑边沿的组件下方的走线将导致感应电容。即使是连接两段接地平面的非常窄的走线也比没有好。在高频下，包括数字逻辑边沿转换，电流往往会沿着包含最少磁通量的路径流动。这意味着地平面返回电流将更倾向于集中在其相应的信号轨道下方。

一些电路板制造商不建议留下大面积的铜，因为这可能会导致电路板翘曲或阻焊剂龟裂。如果这可能是个问题，您可以用交叉影线图案替换实心接地层，而不会降低其有效性。要与接地平面或电路板表面上的任何其他大面积铜进行焊接连接，您应该从接地区域“断开”焊盘并使用较短的走线进行连接。这可以防止接地层在焊接过程中充当散热器以实现可靠的接头。
