Electronic device

The invention provides an electronic device, which comprises a crystal oscillator, a data processor, a switch and a matching network, wherein the crystal oscillator has an actual load capacitance value; the matching network is used for changing the actual load capacitance value of the crystal oscillator; the switch is electrically connected between the crystal oscillator and the data processor; and the data processor is used for detecting the actual load capacitance value of the crystal oscillator and controlling connection/disconnection between the switch and the matching network according to the actual load capacitance value. The electronic device can change the actual load capacitance value of the crystal oscillator, and thus, the debugging time is shortened, and the research and development cycle is reduced.
