A new approach to mitigate PCI express Gen4 crosstalk from sideband signals in connectors

Abstract

RC termination for sideband signals is required in PCIe Gen4 Card Electromechanical specification to reduce crosstalk in PCIe connectors. A new approach to reduce crosstalk is proposed in this paper. This approach doesn't require extra components, and simulation results show that the new proposal can achieve even better electrical performance.
