Claim 3:
4. The clock spread spectrum circuit according to claim 1, wherein the base time unit generation sub-circuit comprises:
a voltage-controlled oscillator, configured to oscillate at a predetermined oscillation frequency;
a phase-locked loop circuit, configured to lock an output frequency of the voltage-controlled oscillator to a base output frequency; and
K output terminals, configured to output K base output signals with phases evenly spaced, wherein K is a positive integer greater than 1,
wherein the base output frequency is expressed as fd, the base time unit is a time span between any two adjacent base output signals output by the K output terminals, the base time unit is expressed as Δ, and Δ=1/(K·fd).
