Signal integrity in reflection-limited channels

High-speed digital signal integrity is strongly limited by microwave reflections, which degrade the reliability of a serial link. This work describes the relationship between the reflections and attenuation that occur along interconnects and the signal integrity. Bounds on ISI and DDJ resulting from reflections and attenuation quantify system design of link jitter budgets. This paper demonstrates analytical methods to quickly deduce the signal integrity penalty of transmission line discontinuities.
