Abstract
A circuit device includes a processor adapted to perform a signal processing of temperature compensation of an oscillation frequency based on temperature detection data from an external temperature sensor disposed outside the circuit device to output frequency control data, and an oscillation signal generation circuit adapted to generate an oscillation signal with the oscillation frequency corresponding to the frequency control data using the frequency control data and a resonator disposed in a thermostatic oven.
