- [PCI Express\<sup\>®\</sup\> Retimers vs\. Redrivers: An Eye\-Popping Difference](https://www.asteralabs.com/pci-express-retimers-vs-redrivers-an-eye-popping-difference/): A redriver amplifies a signal, whereas a retimer retransmits a fresh copy of the signal\. Retimers provide capabilities such as PCIe® protocol participation, lane\-to\-lane skew compensation, adaptive EQ, diagnostics features, etc\. Therefore, retimers particularly address the need for reach extension in PCIe 4\.0 \& PCIe 5\.0 systems, where increased number of PCIe slots, multiconnectors, and long physical topologies lead to signal integrity \(SI\) challenges\.
