How does Samtec “rate” their connectors for Signal Integrity performance?
Please visit the following link: Connector System Speed Rating. The data in Samtec’s High Speed Characterization Test Reports reflects performance in 50 ohm single-ended and 100 ohm differential environments. How differently will the connector perform in other characteristic impedance environments (where the entities of the system – drive circuit, traces, and termination schemes – are designed to the same characteristic impedance) ? (a) Impedance profile of the connector will not change, because the impedance discontinuities inherent to the connector’s design are independent of the characteristic system impedance (b) Propagation delay through the connector will not change because the inductive and capacitive properties inherent to the connector’s design are independent of the characteristic system impedance (c) Crosstalk (percentage of voltage swing) will not be affected. Crosstalk is a measure of the coupling between circuits, and is due to inductive and capacitive coupling within the
