Abstract
Provided is an oscillator including: a first resonator; a second resonator; a first oscillation circuit generating a first oscillation signal by oscillating the first resonator; a second oscillation circuit generating a second oscillation signal that has frequency-temperature characteristics different from frequency-temperature characteristics of the first oscillation signal by oscillating the second resonator; a clock signal generation circuit generating a clock signal with a frequency that is temperature compensated by temperature compensation data; and a processing circuit performing time digital conversion processing based on the first oscillation signal and the second oscillation signal, and obtaining the temperature compensation data based on measurement data of the time digital conversion processing.
