Abstract
Provided is an oscillator including: a resonator; a first circuit device electrically coupled to the resonator; and a second circuit device. The first circuit device generates a first clock signal by causing the resonator to oscillate, and performs first temperature compensation processing for temperature compensating a frequency of the first clock signal. The second circuit device receives the first clock signal from the first circuit device, generates a second clock signal based on the first clock signal, and performs second temperature compensation processing for temperature compensating a frequency of the second clock signal.
