Connectors are a significant source of crosstalk noise in a system, which could increase jitter in the resulting eye pattern. Since crosstalk jitter is uncorrelated from the link data pattern, it is hard to remove through equalization techniques. This paper provides a process to extract accurate coupled models from connectors. It also describes how modeling was used to predict crosstalk noise in a 10 Gbps channel and shows how a small percentage of connector crosstalk can have a significant impact on the over all signal distortion, if the connector pin assignment is done randomly.
