RETIMER PCIe 5.0 adapter card with 2 MCIO 8i (x8) ports for NVMe M.2, M.3, U.2, and U.3 SSDs or PCIe add-on cards

A reminder of what a card with a retimer function is:

• A standard PCIe-to-MCIO card without a retimer is passive: it is simply a connector carrier that routes PCIe lines to SSDs or a backplane. It is simple and inexpensive, but has limited cable length and can sometimes be unstable depending on the system
• A card with a retimer function incorporates a chip that regenerates and stabilizes the signal. It is more expensive because it is more complex, but essential for long links, NVMe backplanes, or modern high-speed configurations, which significantly improves compatibility and reliability.

Based on the Montage M88RT51632 controller, it regenerates PCIe signals to maintain their integrity over extended links. It operates at up to 32 GT/s per lane, supports PCIe Gen 5 through Gen 1 as well as CXL 2.0, and supports 2x8 and 4x4 lane configurations. It is specifically designed for connecting external JBOF-type NVMe storage systems.
