Crystal oscillator and matching capacitor(1)

Matching capacitances-- load capacitors are the capacitors required by the crystal oscillator to oscillate normally. General external capacitance is designed to make the equivalent capacitance at both ends of the crystal equal to or close to the load capacitance. The earth-to-ground capacitance of ic input should also be considered in high-demand occasions. In general, the capacitance at both ends of the crystal oscillator is twice the required load capacitance. In this way, it's close to the load capacitance.
