Abstract
A circuit device includes a first oscillation circuit, a second oscillation circuit, a clock signal output circuit adapted to output a clock signal based on an output signal of the first oscillation circuit, and an output control circuit adapted to perform output control of the clock signal output circuit. The output control circuit includes a counter circuit adapted to perform a counting process based on an output signal of the second oscillation circuit, and the counter circuit outputs an output enable signal of the clock signal to the clock signal output circuit based on a result of the counting process.
