White Paper Explains How Increasing Bus Speeds Degrades Throughput Performance

Bandwidth tests reveal shrinking eye diagrams and signal integrity problems

ASSET InterTech published a white paper titled: Bandwidth tests reveal shrinking eye diagrams and signal integrity problems. The paper explains how increasing bus speeds on circuit boards could create havoc for signal integrity on those buses, in turn degrading the bus’ throughput performance. Each new generation of a high-speed bus typically runs at a higher signal frequency, but this decreases the margin for error on the bus, making it more sensitive to disruptions from jitter, inter-symbol interference (ISI), crosstalk and other factors.
