关于石英晶体谐振器（Crystal unit）的使用说明，晶诺威科技解释如下：

Drive level驱动水平

Applying excessive drive level to the crystal units may cause deterioration of characteristics or damage. Circuit design must be such as to maintain a proper drive level.

对石英晶体谐振器施加过高的驱动电平可能会导致其特性恶化或损坏。电路设计必须保持适当的驱动电平。

Negative resistance负性阻抗

Unless adequate negative resistance is allocated in the oscillation circuit, oscillation start up time may increase.

除非在振荡电路中配置足够的负性阻抗，否则振荡启动时间可能会增加。

Load capacitance负载电容

Differences in the load capacitance in the oscillation circuit may result in deviations in the oscillation frequency from the desired frequency. Attempting to tune by force may merely cause abnormal oscillation. Before use, please specify the load capacitance of the oscillation circuit.

振荡电路中的负载电容的差异可能导致振荡频率与目标频率的偏差。试图通过强制调谐可能只会导致异常振荡。在晶体谐振前使用前，请明确振荡电路的负载电容。
