An information handling system includes a receiver and a transmitter. A margin detector of the receiver derives an eye plot for signals received via a plurality of high speed serial lanes. A first control module of the receiver identifies a weakest lane of the high speed serial lanes, and compares eye plots for a signal on the weakest lane from one crosstalk minimization iteration to the next. A second control module of the transmitter receives a signal from the first control module indicating whether an eye plot of the signal has improved from one crosstalk minimization iteration to the next, and iteratively controls a phase shift of aggressor signals in the high speed serial lanes during each iteration until the eye plot of the signal remains the same from one iteration to the next. A phase shift module of the transmitter phase shifts the aggressor signals during each iteration.
