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 frequency. If the nominal frequency is the same, the load capacitance is not necessarily the same. Because the quartz crystal oscillator has two resonant frequencies, one is the low load capacitive oscillator of the series wiping oscillator and the other is the high load capacitive oscillator of the parallel wiping oscillator. Therefore, the nominal frequency of the same crystal oscillator exchange must also require the same load capacitance ,too. They cannot be inadvertently interchanged. Otherwise it will cause abnormal electrical work.
