ABSTRACT:
A method and an apparatus to reduce electromagnetic interference (EMI) have been presented. In one embodiment, the method includes using a first clock signal to create a second clock signal having a fundamental frequency lower than a frequency of the first clock signal, wherein the first clock signal is used to transmit data from a chip within a chip set to an interconnect. The method may further include outputting the second clock signal to the interconnect via a data channel of the chip as a forwarded clock signal. The signal power may be redistributed to lower fundamental frequency to reduce EMI emission from the system. Other embodiments have been claimed and described.
