Abstract
An oscillator circuit includes an oscillating unit, a counter unit, and a set value generator. The oscillating unit is configured to output an oscillation signal having a frequency corresponding to an input frequency setting value. The counter unit is configured to count a number of pulses of the oscillation signal during a time period corresponding to a period of a reference signal input from outside. The set value generator is configured to generate the frequency setting value every predetermined time period based on the count of the pulses counted by the counter unit.
