Retimers and Redrivers have enabled longer physical channels in servers and storage systems since Peripheral Component Interface Express (PCIe®) 3.0 was first introduced almost 10 years ago. Now that PCIe 4.0 is ramping up and PCIe 5.0 is just around the corner, how do these reach extension tools stack up in the face of new challenges in high-speed connectivity?
This article explains the differences between Retimers and Redrivers in IC block diagram, capabilities and use cases.
