PCIe x8 with ReTimer to SlimSAS 8i SFF-8654 AIC for x8 datalink width PCIe 4.0

‌PCIe x8 Edge Connector

Connects to a host system’s motherboard PCIe slot.

Supports PCIe Gen 4.0 at 16 GT/s per lane, yielding up to 128 GT/s aggregate bandwidth.

ReTimer Chip

Acts as a signal conditioning component to regenerate PCIe signals.

Crucial for maintaining signal integrity over long traces or when connecting through cables (especially over SlimSAS).

Ensures compliance with PCIe 4.0 specifications over extended distances or with non-optimal layout environments.

SlimSAs 8i Connector

Miniature, high-density I/O connector.

The “8i” indicates 8 PCIe lanes carried through one cable.

Often used to route PCIe lanes to NVMe drive backplanes or other PCIe devices (e.g., U.2/U.3 SSDs, GPU expanders, etc.).
