Chapter 13. Measurements on Interconnects
Eugene Mayevskiy and Dimitry Smolyanskiy
As the performance requirements for modern computer and communications systems grow, the demand for high-speed interconnects increases as well. Multigigabit speeds are supported by standard communication technologies, with the signal's rise times being as fast as 24 ps (20% to 80%, Ethernet 10GBase-R [1]). At these speeds, cables, connectors, vias, and traces on printed circuit boards (PCBs), similar to the one shown in Figure 13-1, are best modeled as distributed elements or transmission lines. Moreover, reflections due to impedance mismatch, rise time degradation ...
