SI-Fi^TM PCIe Gen5 Interposers

SerialTek interposers use SI-Fi™, a proprietary probing technology which eliminates the need for hours-long calibration sequences, preserves the original signal quality of the link, and enables real-world PCIe link training debug. With support for OCP 3.0 NIC and EDSFF form factors, these modular, calibration-free interposers are compatible with PCIe 5.0, PCIe 6.0 (PAM4 modulation at 64 GT/s), and SerialTek’s future PCIe 6.0 protocol analyzers.

The new interposers also feature the industry’s first integrated power analysis functionality, powered by Quarch Technology Ltd., providing very high-accuracy measurements of voltage, current, and power. This integration not only eliminates the need for bulky current probes and oscilloscopes or DC power analyzers, but also correlates these measurements to the PCIe traffic in the trace capture.

EDSFF Interposer

SerialTek’s EDSFF interposer is mechanically modular and easily converts from E1.S to E1.L to E3.S form factors. The included EDSFF host adapters are easy to change and plug into a host system. High-quality cabling (instead of lossy PCB material) from the interposer to the storage enclosure preserves signal quality while adding flexibility, saving customers money, and providing for safe placement of the device under test (DUT) on a bench or in a test rack. SerialTek’s EDSFF Interposer supports all relevant sidebands, including SMBus (e.g., NVMe-MI) from the host or from external / third-party injection or generation tools. SerialTek’s PCIe Gen5 EDSFF Interposers with SI-Fi technology are specially designed test adapters that are physically placed in between the EDSFF port and an E1.x or E3.x EDSFF target to intercept and relay a copy of the high-speed signaling and discrete data lines to the Kodiak PCIe Analysis system in real-time.

M.2 Interposer

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 Gen5 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.

U.2 / U.3 Interposer

SerialTek’s U.2 and U.3 interposers support standard and extended length storage bays, and all relevant sidebands, including SMBus (e.g., NVMe-MI) from the host or from external / third-party injection or generation tools. SerialTek’s PCIe Gen5 U.2 and U.3 Interposers with SI-Fi technology are specially designed test adapters that are physically placed in between the U.2/U.3 port and a U.2/U.3 target to intercept and relay a copy of the high-speed signaling and discrete data lines to the Kodiak PCIe Analysis system in real-time.

Cable Interposers

PCIe External Cabling provides an electrically efficient channel to connect external or internal PCIe components directly to a root port, daughter card, backplane, adapter, or other PCIe based ports. Cable interposers support MCIO, HD MiniSAS (SFF-8674) and SlimSAS (SFF-8654) form factors and supports all relevant sidebands, including SMBus (e.g., NVMe-MI) from the host or from external / third-party injection or generation tools. SerialTek’s PCIe Cable Interposers with SI-Fi technology are specially designed test adapters that are physically placed in between the MCIO, HD MiniSAS (SFF-8674) or SlimSAS (SFF-8654) host port and its 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.

The MCIO and SlimSAS Adapter Sets are design to allow link widths greater than x4 and with the modular interposer concept, x4, x8 and x16 Slot (AIC) Interposers are converted to support MCIO or SlimSAS cabling connection.
