摘要： Provided are a clock signal production circuit, a clock signal production method, and an electronic device, relating to the technical field of communications. In the clock signal production circuit, by digital circuits such as a control word generation circuit, an initial clock generation circuit, and a spread spectrum clock generation circuit, a frequency control word is first generated on the basis of spread spectrum parameters, an initial clock signal of a target duty cycle is then generated on the basis of the frequency control word, and spread spectrum processing is finally performed on the basis of the target duty cycle of the initial clock signal and the frequency control word to obtain a spread spectrum clock signal, i.e., the entire spread spectrum process is executed by the digital circuits. Therefore, it is not necessary to control the electronic device comprising the clock signal production circuit to stop working, i.e., the normal operation of the electronic device is not affected. Moreover, according to the clock signal production circuit, real-time adjustment of spread spectrum parameters (such as spread spectrum depth) that affect a spread spectrum result can be implemented, and the spread spectrum flexibility is relatively high.
