Innocard EP8102 PCIe Gen5 adapter
The Innocard EP8102 is a PCIe Gen5 gender changer that converts a single x8 lane into two MCIO 38P ports. It targets system integrators and lab engineers who need to extend high-speed signals to U.3 or similar backplanes. The board includes a ReDriver and clock buffer to maintain link integrity over longer traces. Status LEDs show PRSNT#, 3.3VAUX, 3.3V and inverted PERST#/WAKE# states.
Built-in ReDriver, clock buffer and SMBus controls
Dual MCIO 38P connectors follow the SFF-TA-1016 pinout and ship with two 50 cm cables for rack-to-rack or tray-to-tray routing. A 100 MHz clock buffer at address 0x6C drives 100 ohm impedance for extended reach. An SMBus switch at 0x70 and an I/O expander at 0x20 provide four-channel control and out-of-band reset for each MCIO port. PERST#, WAKE# and CLKREQ# buffer gates further protect signal quality across the cable length.
Replaces passive gender changers that lack signal
Passive adapters cannot compensate for the insertion loss of 5.0 GT/s lanes over 50 cm or longer cables. The EP8102 adds active equalisation, clock regeneration and management buses so the link trains reliably at full width. The jump is worth it when the host-to-backplane path exceeds a few centimetres or when hot-plug and OOB management are required. It is not for builds that stay on a single PCB or use only short passive risers.

Questions about this item
What signal standard does the EP8102 MCIO 38P dual-port adapter convert to PCIe x8 Gen 5?
The adapter converts MCIO 38P (SFF-TA-1016) dual-port signals to PCIe x8 Gen 5 using a built-in ReDriver for signal integrity.
What physical connectors and cable length does the EP8102 include for installation?
The EP8102 includes two MCIO 38P connectors and two 50cm cables for dual-port connectivity.
How is the EP8102 installed and which step is commonly missed?
Install by seating the PCIe x8 card in a Gen 5 slot, connecting both 50cm MCIO 38P cables, and verifying LED1 (AIC PRSNT#) and LED2/3 (3.3V rails) illuminate green.
