High-Speed Front-End for PCIe Gen-3 Cards Reference Design


Design files


This verified reference design is a PCIe Gen-3 high-speed front-end card design to extend the PCB trace distance of  a PCIe sub-system. The board is designed to fit in a x16 lane width PCIe Gen-3 slot between a motherboard and PCIe Gen3 add-in card. This reference design provides users with a useful guideline to incorporate the DS80PCI810 repeater into PCIe Root Complex ASIC and the Add-in Card designs of their own.

  • PCIe Gen-3 Riser Card compatible to a 16-lane PCIe Gen3 slot from Motherboard
  • Extends PCB trace length of a PCIe Gen-3 sub-system
  • Improves signal Integrity and system robustness
  • Seamlessly compatible with link training between host from Motherboard and End-point card
  • Proven design with compliance test report

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
