    摘要： A spread spectrum clock generator (SSCG) and method of generating a spread spectrum clock (SSC) signal, in which the SSCG may include a controller outputting a given modulation voltage signal based on a difference between an average frequency of a first feedback signal and a comparison frequency signal input thereto, or based on comparison in total phase variations between a second feedback signal and the comparison frequency signal, and a sub-system for generating a first control voltage as a function of an input reference frequency signal and a second feedback signal input thereto. An adder may add the first control voltage signal and the modulation voltage signal to generate a second control voltage signal, and a voltage control oscillator (VCO) may generate the SSC signal based on the second control voltage signal.
