With the breakthrough of domestic enterprises in photolithography technology, the trend of electronic products developing towards miniaturization and high precision is becoming increasingly evident. Quartz crystal oscillators have stable hardness and physicochemical properties, and their frequency does not change significantly with temperature. The internal oscillation losses generated by this are also very small, making them very suitable for precision manufacturing. Therefore, domestic enterprises play an increasingly important role in the development of the quartz crystal oscillator industry.

1. The nominal frequency refers to the frequency value of the vibration circuit output under normal matching vibration circuit. Indicate as MHz or KHz. 2. Adjust the frequency difference, with the target being the promised error of the frequency at a certain temperature (25 ℃), expressed as parts per million (ppm). 3. Temperature frequency difference refers to the promised error of the target frequency within the operating temperature range. 4. The temperature scale of the homework, which refers to the temperature scale of quartz crystal components working within the prescribed error range. 5. The storage temperature scale refers to the temperature scale at which a crystal maintains its standard characteristics in a non operational state.

Application principle of passive crystal oscillator circuit: The characteristic of passive crystal oscillator is that it needs to be driven by peripheral circuits to generate oscillating clock signals and cannot start oscillating on its own. In passive crystal oscillator circuits, it is generally necessary to select a suitable external capacitor value for optimal matching, in order to fine tune the frequency of the passive crystal oscillator and make its output frequency as close as possible to the nominal frequency center point.
