摘要： An oscillator includes: a resonator; an oscillation circuit configured to generate an oscillation signal by the resonator; a clock output terminal; an output circuit configured to output a clock signal to an external processing device via the clock output terminal; a first terminal; and an interface circuit configured to execute communication with the processing device by a data signal. In the communication, the output circuit outputs the clock signal to the processing device that is a master for the communication, and the interface circuit that is a slave for the communication receives, via the first terminal, the data signal that is transmitted from the processing device and synchronized with the clock signal, or transmits, via the first terminal, the data signal to the processing apparatus in synchronization with the clock signal.

摘要： A circuit device includes an oscillation circuit that generates an oscillation signal using a resonator, a temperature detection circuit that outputs temperature detection data, a temperature compensation circuit, and a temperature detection rate control circuit. The temperature compensation circuit performs temperature compensation on an oscillation frequency of the oscillation signal based on the temperature detection data. The temperature detection rate control circuit controls a temperature detection rate at which the temperature detection circuit executes temperature detection. At this time, the temperature detection rate control circuit controls the temperature detection rate based on a variation in the temperature detection data.
