摘要：
A clock spread spectrum circuit, an electronic equipment, and a clock spread spectrum method are disclosed. The clock spread spectrum circuit (10) includes a control circuit (11) and a signal generation circuit (12). The control circuit (11) is configured to generate a frequency control word according to a modulation parameter, and the frequency control word changes discretely with time; and the signal generation circuit (12) is configured to receive the frequency control word and generate and output a spread spectrum output signal that is spectrum-spread according to the frequency control word, and the spread spectrum output signal corresponds to the frequency control word.
