Adapter Purpose
The Innocard gender changer converts a U.3 male SFF-TA-1001 PCIe Gen 4 interface to a U.2 female connector. It enables connection of U.2 storage devices to U.3 backplanes or controllers in servers and high-performance computing platforms.
Build Integration
The adapter includes a built-in PCIe ReDriver to extend 16GT/s differential signals and a 100MHz clock buffer for longer trace lengths. Integrated SMBus, PERST#, WAKE#, CLKREQ# and PWRDIS voltage-level translators handle side-band management. Hot-plug power protection IC safeguards the slot during drive insertion.
Sustained Operation
Compliant with PCI Express Base Specification Rev 4.0 and SFF-9402 Version 1.1, the ReDriver and clock buffer maintain signal integrity over extended cable runs. Voltage-level translators ensure stable side-band communication under continuous load in rack, microserver and tower server deployments.

Questions about this item
What is the signal-speed ceiling that appears first when the adapter runs at PCIe Gen 4 continuously?
The on-board ReDriver extends PCIe Gen 4 differential pairs at 16 GT/s, so the 16 GT/s lane rate is the first sustained-use limit.
Does the adapter generate audible noise or measurable heat during all-day operation?
The unit has no fan or active cooling; it relies on passive heat dissipation from the ReDriver and clock-buffer ICs.
Which existing connector must the system already provide for this gender changer to function?
The host side requires an OCulink 4i SFF-8612 port wired to the SFF-9402 Rev 1.1 pin-out.
