The crystal oscillator is the most important component in the clock circuit. Its function is to provide the reference frequency to the parts of the graphics card, network card, motherboard and other accessories. It is like a ruler.

石英晶体振荡器是时钟电路中最重要的元件。其功能是为显卡、网卡、主板等配件的零件提供参考频率，其作用就像一把标尺。

Crystal oscillators are oscillators with a quartz crystal as the primary frequency-determining element. Because of the inherent properties of quartz crystals, the crystal oscillator can be held to extreme frequency stability accuracy. Crystal oscillators are typically fixed frequency oscillators with the primary considerations being stability and accuracy.

晶体振荡器是以石英晶体为主要频率确定元件的振荡器。由于石英晶体的固有特性，晶体振荡器可以保持极高的频率稳定性精度。晶体振荡器通常是固定频率振荡器，主要考虑因素是稳定性和精度。

The crystal oscillator contains circuit that generates an output signal without necessity of an input signal. It is a circuit that produces a repetitive waveform on its output with only dc supply as input. The oscillator can be sinusoidal or non-sinusoidal type.

石英晶体振荡器是一种在无需输入任何信号的条件下即可生成输出时钟信号的电路。它是一种仅以直流电源作为输入，在其输出端产生重复波形的电路。

The crystal oscillators play an important role in a wide range of electronic devices. A quartz watch, for example, uses a quartz oscillator to keep track of time. An oscillator is used in an AM radio transmitter to generate the carrier wave for the station, and a resonator is used in an AM radio receiver to tune in to a station. Oscillators can be found in computers, smart devices, and even man-made satellites.

石英晶体振荡器在各种电子设备中发挥着重要作用，例如，石英表使用石英振荡器来提供时间。在AM调频广播设备中使用振荡器为电台产生载波，在AM收音机中使用谐振器来调谐到电台。振荡器广泛应用于计算机，各类智能电子设备甚至人造卫星中。
