Data-dependent jitter and crosstalk-induced bounded uncorrelated jitter in copper interconnects

摘要

This paper resolves the jitter impairment of non-return-to-zero data in transmission lines. The limited bandwidth of the transmission line introduces data-dependent jitter. Crosstalk between neighbouring lines results in bounded uncorrelated jitter in the data eye. An analytical approach to representing data-dependent jitter and crosstalk-induced bounded uncorrelated jitter is presented. Comparison with jitter measurements of microstrip lines on FR4 board demonstrated accuracy to within 15% of the predictions for deterministic jitter.
