    Abstract: A clock signal generation circuit and method, and an electronic device are provided, relating to the field of communications technology. In the clock signal generation circuit, an initial clock providing circuit (10) can generate an initial clock signal having an initial frequency; a control word providing circuit (20) can determine a target frequency offset of the initial frequency based on a detected target parameter and generate a frequency control word based on the target frequency offset; a target clock generating circuit (30) can generate a target clock signal having a target output frequency based on the frequency control word and the initial clock signal, wherein the target output frequency is negatively correlated with the frequency control word and positively correlated with the initial frequency. It can be learned based on a relationship among the target output frequency and the initial frequency and the frequency control word that flexibly generating the frequency control word can reduce the impact of the target parameter on the frequency of the clock signal finally generated by the clock signal generation circuit.

    Abstract: 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.
