A multi-port information communication system includes a reference clock signal generator configured to generate a reference clock signal. The system also includes a phase controller configured to generate a plurality of information communication clock signals based on the reference clock signal by staggering a phase of each of the information communication clock signals. The phase controller includes a delay-locked loop configured to generate a plurality of delay-locked loop signals based on the reference clock signal, and a plurality of time delay elements. Each time delay element is configured to produce a respective one of the information communication clock signals by adding a respective delay to a respective one of the delay-locked loop signals. The system includes information communication devices each including a respective transmitter. Each of the transmitters is configured to operate in response to a respective one of the information communication clock signals.
