SI-Fi™ PCIe Gen4 Interposers


SI-Fi™ PCIe Gen4 AIC Interposer

SerialTek SI-Fi™ Interposers Announcement

Product Description


Together with the new Kodiak™, SerialTek’s Gen4 (16.0 GT/s) PCI Express® (PCIe®) and Non-volatile Memory Express® (NVMe®) interposers with SI-Fi™ allow users to monitor an unprecedented variety of PCIe and NVMe bus traffic with unparalleled power and ease.

Enabled by SerialTek’s proprietary SI-Fi™ technology, users can save hours over legacy approaches requiring interposer calibration. This technology improves critical test coverage by providing high signal integrity, even over changing conditions, such as link training (LTSSM), Power Management, Hot Plug, Reset, and other tests where the physical link/lane characteristics may change.

Each lane’s analog signal is received at the probe’s differential input and distributed to two separate phase matched differential outputs with a nominal gain of 0dB, allowing the Host and Device signals to pass through the interposer, allowing for real-world PCIe link training and easier set-up of the analyzer and DUT.

SI-Fi™ PCIe Gen4 Interposers continue SerialTek’s TCO approach. With the focus on signal integrity, flexible, low-cost, SFF-8644-based cables connect each interposer to the analyzer. These cables are readily available and rated greater than 20GHz, resulting in uncompromised SI at all PCIe transfer rates.

All sideband signals are passed through the interposer from Root Complex (Host) to Controller (Device), and all are made available to the analyzer for trigger, decode, and analysis.

“I’ve been using protocol analyzers for 31 years and PCIe analyzers and interposers extensively for the past 5 years. We use them for important assignments that affect revenue and customer satisfaction,” said John Wehman, Principal Applications Engineer at Phison Technology. “With other analyzers I have had to abandon my testing many times, because I could not find a good quality signal lock. SerialTek’s Kodiak analyzer and SI-Fi interposers have changed all that. I have 100% confidence in Kodiak’s ability to achieve lock and give me the trace I need to do my job. Kudos to Ellisys and SerialTek for creating not only an electrically reliable platform, but the actual mechanical hardware itself is beautiful.”

Key Features


  • SI-Fi™ Interposers require no calibration
  • Supports PCI Express Gen 1.0, 2.0, 3.0, and 4.0
  • Accurate capture of PCIe data traffic at line rates including 16.0 GT/s (Gen4), 8.0 GT/s (Gen3), 5.0 GT/s (Gen2), and 2.5 GT/s (Gen1)
  • Single U.2 / U.3 interposer supports both single-port and dual-port capture (only one analyzer is needed for dual-port)
  • “Passive” tapping to avoid masking, hiding, or “cleaning up” electrical and/or link issues
  • Low-cost, flexible, high-performance cabling for reliable analyzer to interposer connections

Gen4 Slot/AIC Interposer


PCI Express slots are ubiquitous in ATX or ATX-based form factors in computing, storage, networking, and communication equipment applications. SerialTek’s PCIe Gen4 x4 slot interposer supports analysis of x1, x2, and x4 link-widths, though endpoints up to x16 may be plugged into the interposer. All relevant sidebands, including SMBus (e.g., NVMe-MI) from the host or from external / third-party injection or generation tools are supported. SerialTek’s PCIe Gen4 Slot (AIC) Interposers with SI-Fi technology are specially designed test adapters that are physically placed in between the PCIe slot and a PCIe 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.

Cable Interposer


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. SerialTek’s PCIe cable interposer is a modular, cost-saving design, making setup simple with captive thumbscrews to easily change cable form factors.  The cable interposer supports OCuLink (SFF-8611), MiniSAS-HD (SFF-8674), and SlimSAS (SFF-8654) form factors and can use the same or different form factors at the same time (e.g. OCuLink to SFF-8674). SerialTek’s PCIe Cable 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 Gen4 Cable Interposers with SI-Fi technology are specially designed test adapters that are physically placed in between the OCuLink (SFF-8611), MiniSAS-HD (SFF-8674), and 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.

EDSFF Interposer


SerialTek’s EDSFF interposer is mechanically modular and easily converts from E1.S to E1.L to E3.S form factors in a single unit.  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 Gen4 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.
