Load capacitance refers to the sum of all effective capacitors connected by two lead of crystal oscillator inside and outside IC blocks, which can be regarded as series capacitors of crystal wafers in the circuit. The oscillation frequency of the oscillator is different depending on the load frequen

In general, increasing the load capacitance will decrease the oscillation frequency, while decreasing the load capacitance will increase the oscillation frequency.

Load capacitance refers to the external total effective capacitance across the two ends of the crystal in the circuit. It is a test condition as well as a usage condition. In application, the accurate frequency can be obtained by adjusting the load capacitance value. The size of the capacitor mainly

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 i
