Abstract
An oscillator includes a resonator, an oscillation circuit, and first and temperature compensation circuits. The first temperature compensation circuit performs a first-order first temperature compensation processing in a first mode and performs the first-order first temperature compensation processing and a high-order first temperature compensation processing in a second mode for a frequency of a first clock signal generated by oscillation of the resonator by the oscillation circuit. The second temperature compensation circuit receives the first clock signal and outputs a second clock signal subjected to a high-order second temperature compensation processing based on the first clock signal.
