PCIe Gen5 adapter with ReDriver
The Innocard EP6121 converts a PCIe x16 Gen5 slot to dual MCIO 74P ports. It targets system integrators building high-density storage or accelerator backplanes that require lane bifurcation and signal extension. The board includes a ReDriver controller to maintain 32 GT/s integrity across longer traces or cables.
Installation notes and common issues
The adapter plugs into a standard PCIe CEM slot and draws auxiliary power from the connector. Installers must ensure the host firmware supports x4/x4/x4/x4 bifurcation; otherwise only the first port will enumerate. Misaligned MCIO cables or bent connector pins are the most frequent cause of link training failures.
Sustained-load behaviour
Under continuous 32 GT/s traffic the on-board ReDriver applies up to 22 dB of CTLE boost at 16 GHz to compensate for insertion loss. The 3.3 V, 5 A buck regulator with Eco-mode and the 12 V, 5 A high-side controller keep voltages stable during prolonged transfers. The clock buffer and SMBus expander maintain link management without host intervention.

Questions about this item
How can I verify the EP6121 is extending PCIe 5.0 signals correctly after installation?
The built-in ReDriver controller extends PCIe 5.0 at 32 GT/s across 16 lanes with programmable linear equalisation and flat gain, while the clock buffer at address 0x6C drives longer PCB traces and cable lengths.
What connectors and power features are included on the EP6121, and is a separate power cable required?
The adapter provides dual MCIO 74P ports with 30u inch gold plating, draws +12 V and 3.3 V aux from the PCIe CEM slot, and includes on-board TVS protection, a 5 A high-side 12 V controller, a 3.3 V 5 A buck converter and load switches — no external power cable is needed.
Which lane-width configuration should I select for my topology using the EP6121?
The 16 PCIe lanes can be bifurcated into four x4 links, allowing you to match the dual MCIO 74P ports to your system topology.
