Abstract
A clock source is configured to provide an oscillating signal to be divided into a clock signal. A temperature sensor senses a first temperature of the clock source. The clock source is subjected to at least one second temperature implemented by a temperature alteration module. A calibration module calibrates the clock signal based on the at least one second temperature, the first temperature, a reference signal, and the oscillating signal at the at least one second temperature.
