摘要：
A method for applying spread spectrum noise reduction techniques to USB specifically USB2.0 communications systems includes the step of generating a base (seed) frequency for the USB system, modulating the base (seed) frequency with a spread spectrum (SS) characteristic, and utilizing (as-is, not modified) the existing ASIC that multiplying the now modulated base (seed) frequency to generate the USB standard frequency signaling rate of 480 MHz with the SS characteristic within the USB standard specification for frequency deviation.
