Abstract
An oscillator includes a resonator element, an oscillation circuit configured to oscillate the resonator element to generate a clock signal, a temperature sensor, a digital control circuit configured to operate based on the clock signal and output a control signal based on a temperature detected by the temperature sensor, a temperature control circuit configured to output a control voltage based on the control signal, a temperature control element configured to control a temperature of the resonator element based on the control voltage, and a clock signal abnormality detection circuit configured to detect an abnormality in the clock signal. The clock signal abnormality detection circuit stops an output of the control voltage to the temperature control element performed by the temperature control circuit when the abnormality in the clock signal is detected.
