Abstract :
This paper provides a tutorial review of spread spectrum clock generators (SSCG). After explaining the various EMI reduction techniques, SSCGs which reduce EMI with frequency modulation are presented. The frequency modulation method and its implementation are also introduced. A low-cost SSCG design method that does not sacrifice EMI reduction is presented. The paper concludes with future trends of SSCGs.
