5 Summary

Equalization is a powerful analog capability that is used by almost all PCIe signal conditioning devices. By compensating for insertion loss in the signal path, the reach of the entire link can be extended, and linear redrivers that focus on equalization can perform this invisibly without interrupting the activities of the root complex and endpoint. There are still a number of more subtle factors such as filter shaping and device placement that can influence the performance of the redriver. Therefore, a deeper fundamental understanding of equalization can aid the successful implementation of PCIe redrivers, from the earliest stages of board design to the final stages of system testing and validation.
