There is a growing trend in industry to characterize high-speed links in terms of their integrated crosstalk noise (ICN) tolerance at different insertion losses. The slope of the insertion loss vs. ICN plot (typically in dB/mV) is now becoming one of the key metrics to evaluate and compare the performance across different systems. In this paper, a mathematical analysis and simulation methodology is presented on how to calculate the total ICN which can be tolerated in the presence of other impairments such as thermal noise, residual ISI, and timing jitter. The accuracy of the mathematical analysis is confirmed by statistical simulations.

Takeaway

An overview of link modelling and different methods for calculating integrated crosstalk noise is presented. A mathematical analysis and simulation methodology is presented on how to calculate the total ICN which can be tolerated in the presence of other impairments such as thermal noise, residual ISI, and timing jitter.

Intended Audience

Familiarity with channel parameters such as crosstalk and insertion loss. Basic understanding of power spectral density and random variables and probability.
