A clock integrated circuit is provided. The clock integrated circuit includes: a first clock generator which includes a crystal oscillator configured to generate a first clock signal; and a second clock generator which includes a resistance-capacitance (RC) oscillator and a first frequency divider, and is configured to: generate a second clock signal using the first frequency divider based on a clock signal output from the RC oscillator; perform a first calibration operation for adjusting a frequency division ratio of the first frequency divider to a first frequency division ratio based on the first clock signal; and perform a second calibration operation for adjusting the first frequency division ratio to a second frequency division ratio based on a sensed temperature.
