SI-Fi™ PCIe Gen5 Interposers


Kodiak Gen5 AIC Interposer

Product Description


SerialTek’s PCIe Gen5 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. Together with the Kodiak™, SerialTek’s Gen5 (32.0 GT/s) PCI Express® (PCIe®) interposers with SI-Fi™ allow users to monitor an unprecedented variety of PCIe 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.

SI-Fi™ PCIe Gen5 Interposers continue SerialTek’s TCO approach. With the focus on signal integrity, QSFP-DD based cables connect each interposer to the analyzer. These cables are readily available and rated greater than 32GHz, 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.”

 

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.
