Abstract: Various embodiments associated with a DCXO installed in an electronic device are described. An electronic device may include: a frequency determining unit configured to determine a delta frequency corresponding to a difference between a first frequency for RF communication and a second frequency output from a frequency synthesis unit; a digitally-controlled crystal oscillator (DCXO) configured to comprise a plurality of capacitors including a first variable capacitor and a second variable capacitor, and an oscillator connected to the plurality of capacitors and outputting a clock; and a processor configured to change capacitances of the first variable capacitor and the second variable capacitor by applying a first control value to the first variable capacitor and applying a second control value to the second variable capacitor, based on the delta frequency. Other various embodiments may be possible.
