M.2 is a specification supporting specifically keyed modules of different lengths that facilitate the addition or expansion of functions via a small form factor. The PCIe M.2 form factor is typically used for PCIe adaptation and small form factor NVMe SSD’s. SerialTek’s M.2 interposer supports all relevant keys, link-widths, and sidebands, including SMBus (e.g., NVMe-MI) from the host or from external / third-party injection or generation tools. SerialTek’s PCIe Gen4 M.2 Interposers with SI-Fi technology are specially designed test adapters that are physically placed in between the M.2 port and an M.2 endpoint to intercept and relay a copy of the high-speed signaling and discrete data lines to the Kodiak PCIe Analysis system in real-time.
