SI-Fi™ OCP-Compliant PCIe® 6.0 & CXL® Interposer

SerialTek’s PCIe 6.0 Interposer with SI-Fi™ (Signal Integrity Fidelity) 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 6.0 (64 GT/s) PCI Express® (PCIe®) interposers allow users to monitor an unprecedented variety of PCIe bus traffic with unparalleled power and ease.

 

PRESS RELEASE

Protocol and Power Analysis for OCP NICs and SSDs at 64 GT/s

SerialTek’s OCP-Compliant PCIe® 6.0 and CXL® 3.0 Interposer is engineered to help hyperscale data center and AI/ML engineers capture, analyze, and optimize next-generation hardware with confidence.

Purpose-built for OCP NIC 3.0 and EDSFF form factors, this advanced interposer supports data rates up to 64 GT/s and leverages SerialTek’s proprietary SI-Fi™ (Signal Integrity Fidelity) technology to ensure exceptional capture fidelity. The result is a powerful solution that enables engineers to validate interoperability, performance, and compliance at the forefront of PCIe® Gen6 and CXL® innovation. The OCP NIC 3.0 interposer pairs with Quarch’s QTL2312 Power Analysis Module to capture synchronized protocol + power data — critical for optimizing performance and efficiency in hyperscale deployments. Shipping now and available now with support for MCIO, CEM, M.2, and EDSFF connections. Backed by SerialTek’s proven PCIe® and NVMe® expertise since 2007.

“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. 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.” — John Wehman, Principal Applications Engineer, Phison Technology

SerialTek OCP 3.0 NIC and EDSFF standard form factor interposers use SI-Fi™, a proprietary probing technology which eliminates the need for hours-long calibration sequences (for link speeds up to PCIe 5.x only), 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 Adapters SerialTek’s OCP interposer is mechanically modular and easily converts from E1.S to E1.L to E3.S to E3.L 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 OCP 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 OCP Interposer 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 Adapters 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 A, E, and B 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 6.0 OCP 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 Adapters SerialTek’s U.2 and U.3 adapters for the OCP Interposer 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. The U.2/U.3 form factor is in active development, with release expected soon. Stay tuned for availability announcements.
AIC/CEM Adapter 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. 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 OCP Interposer and AIC/CEM adapters with SI-Fi technology are specially designed test adapters that are physically placed in between the 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.
