  • Integrated clock buffer and SMBus switch simplify out-of-band management and cabling

Innocard EP6121 PCIe Gen5 adapter

The Innocard EP6121 converts an MCIO 74P interface to a PCIe x16 Gen5 connection with dual port SFF-TA-1016 support. It targets system integrators building high-density server or workstation platforms that require reliable lane extension. The board includes a ReDriver controller to maintain signal integrity at 32 GT/s across 16 lanes.

Replaces direct backplane routing

This adapter replaces custom backplane trace routing when longer reach or flexible topology is needed. The jump is worth it when physical layout constraints prevent native PCIe 5.0 trace lengths or when bifurcation into four x4 links simplifies system design. Built-in clock buffering and SMBus switching reduce external component count.

Sustained signal integrity under load

The ReDriver provides programmable linear equalization and flat gain with CTLE boost up to 22 dB at 16 GHz to counteract insertion loss over extended traces. Power delivery includes 12 V input with TVS protection rated for 400 W peak pulse dissipation and a 5 A high-side controller. On-board buck conversion supplies 3.3 V at 5 A with Eco-mode while load switches protect the ReDriver and bus buffer ICs during faults.

Questions about this item

What motherboard slot and power connector does the EP6121 require?

It plugs into a PCIe x16 CEM slot and draws +12 V and 3.3 V aux power directly from that slot.

Which step is most often missed when installing the ReDriver adapter?

Ensuring the on-board 100 MHz clock buffer at address 0x6C and the SMBus switch at 0x70 are enabled in BIOS so the dual MCIO 74P ports can negotiate link training.

What wear item on the EP6121 will need attention first?

The MCIO 74P mating area is plated with 30 µin gold; repeated cable insertions will eventually wear this coating and require connector replacement.
