PCIe x8 Gen 5 ReDriver adapter
This Innocard add-in card converts a PCIe x8 Gen 5 slot to an SFF-TA-1016 MCIO 74-pin interface. It includes an integrated ReDriver controller that extends 32 GT/s signals across eight lanes with programmable equalisation. The board is designed and manufactured in Taiwan.
Builders extending PCIe 5.0 over MCIO cabling
The card suits system integrators who need to route eight lanes to a backplane or external enclosure while preserving signal integrity at 16 GHz. It is not intended for direct device attachment without an MCIO interconnect, nor for workloads that require x16 electrical width.
Eight lanes with 22 dB CTLE headroom
The ReDriver provides up to 22 dB of continuous-time linear equalisation at 16 GHz, supporting longer PCB traces and cable runs. Bifurcation allows two x4 topologies, but the electrical budget remains eight lanes total. Beyond that width or without MCIO cabling the adapter cannot be used.

Questions about this item
Does my server motherboard need a free PCIe x8 Gen 5 slot with CEM 3.3 V auxiliary power to use this adapter?
Yes, the card draws 3.3 V and auxiliary 3.3 V from the PCIe CEM connector and uses load-switch protection for the ReDriver controller, SMBus switch and expander.
Will the built-in 100 MHz clock buffer and PERST# bus buffer let me run longer cables to older PCIe 4.0 or 3.0 endpoints?
The clock buffer at address 0x6C and PERST# bus buffer are designed to extend PCB trace reach and cable length for the MCIO 74P link at up to 32 GT/s across 8 lanes.
How can I verify the ReDriver is active and the link is running at 32 GT/s after installation?
Check the ReDriver controller registers for the programmed CTLE boost up to 22 dB at 16 GHz and confirm the PCIe link training reports 5.0 32 GT/s x8 or bifurcated x4 widths.
