System and method for reducing electromagnetic interference and ground bounce in an information communication system by controlling phase of clock signals among a plurality of information communication devices

A communication system comprising:

• a plurality of communication devices configured to operate according to a plurality of communication clock signals, respectively, wherein the plurality of communication clock signals are based on a common reference clock signal;
• a phase-locked loop configured to generate an output signal in response to the common reference clock signal, wherein the output signal is in phase lock with the common reference clock signal;
• a signal division controller configured to generate a divider reset signal in response to a binary select signal;
• and
• a divider configured to generate one of the plurality of communication clock signals by performing frequency division of the output signal, wherein the divider reset signal controls a start time of the frequency division,
• wherein the signal division controller is configured to generate the divider reset signal, according to the binary select signal, at one of a rising edge of the output signal and a falling edge of the output signal.
