Correlation of crosstalk and power noise induced ringback and jitter in an LPDDR interface

This paper presents a correlation study and a practical investigation of noise phenomena in an LPDDR interface induced by power noise and crosstalk. Comprehensive simulations of a test vehicle are performed and correlated against measurements for well-designed experiments. The simulations themselves include several levels of complexity ranging from SI-only based simulations, to SI/PI co-simulations. From the investigations, the relative contributions of power noise and crosstalk to eye degradation, are assessed.
