Abstract
A circuit device includes a clock signal generation circuit that generates a clock signal, an output circuit that outputs an output clock signal based on the clock signal, and a clock terminal that outputs the output clock signal. The circuit device further includes a test terminal, a storage circuit that stores a duty adjustment value, and a duty adjustment circuit that adjusts a duty of the clock signal based on the duty adjustment value. The output circuit outputs a first DC voltage based on a normal rotation signal of the clock signal to the test terminal in a first state. The output circuit outputs a second DC voltage based on a reverse rotation signal of the clock signal to the test terminal in a second state.
