由于MCU系列0或无线MCU系列0中的进口晶体振荡器使用相对较低的振荡幅度，当使用建议的负载电容时，振荡频率可以低于数据表中规定的。这种偏移最好通过测量来发现使用建议的负载电容时产生的频率。偏移量稳定，不受温度、电压的影响或老化。如果想要达到晶体给定的标称频率，有两种选择:

选项A -从晶体供应商订购一个晶体，其名义频率等于你想要实现的频率加测量的偏移频率。

选项B -可以通过调整负载电容(CL1和CL2)来略微改变晶体的振荡频率。

振荡系统的可拉性是指在多大程度上可以通过改变晶体的共振频率来调节这些值。晶体看到这些电容器串联通过地面，平行于闭环。因此，它们会略有变化晶体的反共振频率。下面的公式显示了在频率变化方面的可拉性ppm每pF中组合负载电容的变化。

驱动电平是衡量晶体中耗散的功率的一个指标。晶体制造商应指定最大功耗晶体数据表中晶体容忍的值。超过这个值会损坏晶体。

I是流过晶体的均方根电流。如果需要，可以增加一个外部电阻来限制驱动电平;然而这是除非DL太高，否则不建议使用，因为它会降低增益裕度，增加振荡器的功耗。

振荡形成的一个临界条件要求提供的能量超过电路中耗散的能量。换句话说,放大器的负电阻必须超过晶体中的等效串联电阻。负电阻的近似公式如下式所示。

其中gm为振荡器电路的跨导。为了确保安全运行在所有电压和温度变化最低允许Rneg由下式给出。

如果负电阻不够高，不能满足这一标准，另一晶体低ESR和/或负载能力的要求应该选择。simple Studio中的[硬件配置器]中的XO配置器能够为您计算Rneg值根据负载和并联电容、内部损耗和频率进行设计。的近似公式由上式可知此计算不包括并联电容和内部损耗。

频率稳定性是指在给定的工作温度范围内，与指定振荡频率的最大频率偏差的范围内。

频率公差是指在25°C时，与规定振荡频率的最大频率偏差。此参数给出一个表示单个晶体之间的变化。
