SI-Fi Gen4 PCIe/NVMe Interposers

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.

Product Description

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.”
