An improved DDR interface uses single-ended technology and phase-shifts all output data signals and the output source clock signal so that each output signal switches at a different time so that IDDQ spikes caused by I/O switching do not accumulate. A dynamic phase adjustment circuit on the receiver compensates for the phase differences. Clock jitter and skew is reduced and the number of IDDQ pins is reduced to provide a more effective design and high density package.
