Innocard PCIe x8 Gen 4 ReDriver Adapter
This Innocard adapter converts a PCIe x8 Gen 4 slot to a SlimSAS 8i interface with an integrated ReDriver. It supports signal extension for 16 GT/s differential pairs across eight lanes. The board includes clock and side-band buffers for longer cable runs. A green LED indicates when the add-in card is ready.
Builders extending PCIe Gen 4 over SlimSAS cables
This suits builders who need to route PCIe Gen 4 signals over longer SlimSAS 8i cables using the SFF-8654 connector defined by SFF-9402 Rev 1.1. It is not for systems lacking a PCIe x8 Gen 4 slot or for direct device attachment without cabling. Buyers needing a different connector type or lane configuration should look elsewhere.
Integrated buffers and LED status indicator
The on-board PCIe ReDriver extends 16 GT/s signal reach across eight lanes. A 100 MHz clock buffer drives longer traces and cables. Bidirectional buffers handle SMCLK and SMDAT, while dedicated gates buffer PERST#, WAKE#, CLKREQ# and PWRBRK#. The green D1 LED provides a simple ready-state visual check.

Questions about this item
What motherboard slot is required for the PCIe x8 Gen 4 16GT/s interface to function?
A PCIe x8 slot running at Gen 4 speed is needed so the 16GT/s lanes and the on-board ReDriver can operate at full rate.
Will the built-in 100MHz clock buffer and PERST# gate allow a longer SlimSAS 8i cable to work with an older Gen 3 backplane?
Yes, the clock buffer, PERST# gate and SMCLK/SMDAT repeater are designed to maintain signal integrity over extended trace lengths at Gen 4 rates, so they also support the lower Gen 3 frequencies used by older backplanes.
Which LED confirms the adapter is powered and the link is trained after installation?
The green D1 LED illuminates when the AIC is ready, indicating power is present and the PCIe link has completed training.
