発振器。[Scope of Claim for Utility Model Registration] An oscillation element consisting of a crystal resonator, a variable capacitance element for controlling the oscillation frequency, a memory in which data for temperature compensation is written, and an oscillation element that controls the temperature around the oscillation element. By applying temperature compensation data corresponding to the detected temperature to the variable capacitance element, a constant oscillation frequency can be obtained regardless of temperature fluctuations. A crystal oscillator with temperature compensation function.
