PCIE series Final Inch designs in PCI Express applications generation 1-2.5Gbps
Author: Samtec Inc.

A single Samtec PCIE Series through hole connector in a board-to-edge card configuration can be used in PCI Express systems with total trace lengths not to exceed 13.9 inches when used with Samtec's Final Inch outing, breakout, and trace width solutions. Because loss is the dominant contributor to system degradation, designers should be aware that using smaller trace widths, laminates with higher loss tangent, and sub optimal routing solutions with higher pair-to-pair coupling and additional via stubs will decrease overall performance and the maximum allowable trace length.
