Innocard EP8102 PCIe Gen5 gender changer

SKU CH-E5WN-ZF0GX

Converts dual-port MCIO 38P to PCIe x8 Gen 5 with built-in ReDriver for extended signal reach

  • Changer TypePCIe Gen5
  • Converts dual MCIO 38P ports to PCIe x8 Gen5 with integrated ReDriver
  • Built-in 100 MHz clock buffer drives longer traces at 100 ohm impedance
  • SMBus switch and I/O expander enable out-of-band management for remote resets
  • PERST#, WAKE# and CLKREQ# buffers maintain signal integrity over extended cable lengths
  • Six status LEDs show PRSNT#, 3.3 V auxiliary, 3.3 V and inverted PERST#/WAKE# states

PCIe Gen5 gender changer

The Innocard EP8102 converts a PCIe x8 Gen 5 slot to dual MCIO 38-pin ports using the SFF-TA-1016 standard. It includes a ReDriver to maintain signal integrity over longer traces and two 50 cm cables for internal routing. The adapter targets system integrators and developers who need to extend PCIe 5.0 lanes to backplane or storage connectors. Built-in clock buffers and SMBus switches manage link training and out-of-band control.

Thermals noise and power draw

The board draws 3.3 V and 3.3 V auxiliary rails through the PCIe slot and indicates rail status with green LEDs. No active cooling or fan is present, so the device adds negligible acoustic load to the chassis. Power consumption is limited to the ReDriver, clock buffer and logic circuits required for signal extension. The PERST#, WAKE# and CLKREQ# buffers are designed to operate reliably across the extended cable length.

Upgrade path and fit

This adapter replaces a direct PCIe-to-MCIO cable when signal reach exceeds standard trace limits. The jump is worth it when the backplane or U.2 cage sits farther than the motherboard allows for clean Gen 5 operation. It does not serve builds that need x16 bandwidth or single-port MCIO connections. Buyers who require a different lane split or connector pitch should look elsewhere.

Questions about this item

How do I connect the two 50 cm cables to the MCIO 38P dual port on the EP8102?

Plug each cable into one of the two MCIO 38P (SFF-TA-1016) ports on the adapter; the built-in ReDriver and clock buffer handle the longer reach.

Which onboard components may need attention after extended operation?

The ReDriver, clock buffer, SMBus switch, I/O expander and PERST/WAKE/CLKREQ buffers are all soldered; no user-serviceable parts are specified.

What signal integrity limit appears first when the link runs continuously at PCIe 5.0 speeds?

The ReDriver extends the 8-lane data link reach, so cable length and trace loss become the limiting factor before the redriver saturates.
