Our webinars will be presented by PCI-SIG technology experts from leading technology companies.

In Artificial Intelligence (AI) and Machine Learning (ML) applications, where data demands and processing speeds are continually increasing, ensuring robust signal integrity in PCI Express® (PCIe®) channels is critical. This PCI-SIG® webinar will provide a comprehensive look at the signal integrity challenges inherent to high-bandwidth AI applications, including jitter and crosstalk, and the new implications introduced by the evolution from PCIe 5.0 to PCIe 6.0 and PCIe 7.0 specifications and the transition to PAM4 signaling.
Technical experts from Astera Labs, Samtec and Synopsys will explore the pivotal role PCIe technology plays in enabling high-performance, reliable connections in AI/ML infrastructures. Beginning with an overview of the common signal integrity challenges, the discussion will cover Nyquist frequency changes from the PCIe 5.0 specification through the PCIe 7.0 specification (targeted for release in 2025), and examine how the transition to PAM4 signaling helps to achieve acceptable Bit Error Rate (BER) thresholds. The presenters will review the PCI-SIG defined channel for CEM AICs and extenders for PCIe 5.0 and 6.0 specifications. They will also cover the impacts of crosstalk from AI architectures that demand numerous PCIe PAM4 lanes to switch simultaneously on die and the package, using a case study to highlight real-world challenges.
Attendees will gain insight into the PICMG COM-HPC defined channels for PCIe 5.0 and 6.0 specifications and understand the channel loss budgets – both for internal and external cabling – and the role of retimers to extend reach while maintaining signal integrity. Join the educational webinar to learn the latest advancements and best practices for maintaining error-free, high-speed connectivity across evolving PCIe channels.

Ensuring PCI Express® Signal Integrity for AI/ML Architectures

As the role of PCI Express® (PCIe®) technology expands in new areas such as AI/ML, PCI-SIG® has recognized the need to support multi-path fabrics with an ordering model to improve PCIe bandwidth and reduce latency while maintaining backwards compatibility. 
Unordered IO (UIO) is a new feature added to the PCIe 6.1 specification that defines a new wire semantic protocol and related capabilities for addressing the limitations of the existing PCIe fabric-enforced ordering rules, while keeping the producer-consumer ordering model intact. UIO is a key enabler for Multi-Link PCIe devices (i.e., non-tree topologies). UIO also helps improve the interaction with other protocols, including on-die/on-package protocols, such as CXL, UCIe, etc. 
Attendees of this webinar will understand the traditional PCIe ordering model, the system-level considerations and tradeoffs for deploying PCIe Unordered IO, and will learn which applications and market segments will benefit most from deploying UIO.

Unordered IO for Improving Performance and Efficiency of PCIe® Fabrics

As the need for PCI Express® (PCIe®) cabling has grown, PCI-SIG® has kept pace with the industry demand for high-speed cabling solutions in applications like disaggregated servers, data center networking, storage, AI, automotive and more. In May 2024, PCI-SIG released the CopprLink™ Internal and External specifications for PCIe 5.0 and 6.0 technology, providing internal and external cabling solutions at 32.0 and 64.0 GT/s. 
The release of the CopprLink Internal and External specifications is the latest step on a journey toward PCIe cabling solutions that meet evolving industry needs. By providing internal and external cables of varying speeds and reach that utilize existing connector form factors, PCI-SIG is ensuring the industry can choose the best PCIe cabling solution for their applications.

Celebrating 20 Years of the PCI Express® Specification

PCI-SIG® Compliance Workshops are events where PCI-SIG members can participate in interoperability and compliance testing for the PCI Express® (PCIe®) products. Interoperability tests enable members to test their products against other members’ products, while Compliance tests allow for product testing against PCI-SIG test modules. In 2022, PCI-SIG introduced PCIe 5.0 Compliance Testing to members. PCIe 5.0 Specification Official Testing includes 32 GT/s maximum link speed. 
This webinar presented by Teledyne LeCroy will explore Protocol and Electrical Compliance Testing for PCIe 5.0 systems. Electrical testing examines platform and add-in card transmitter and receiver characteristics, while protocol testing examines a device’s link-level and transaction-level protocol behavior. Attendees will receive an overview of PCIe 5.0 Protocol Compliance Testing, including form factors, lane margining, and link and transaction layer tests. Finally, attendees will learn about PCIe 5.0 Electrical Compliance Test procedures such as transmitter electrical, transmitter link equalization, phase-locked loop (PLL) bandwidth and reference clock jitter.

The History of PCI IO Technology: 30 Years of PCI-SIG® Innovation

Automotive vehicle infrastructures are evolving towards a distributed architecture with multiple safety-critical electronic control units (ECUs) close to the sensors that transmit live, data from all points of a car to other ECUs to make real-time decisions. As ECUs become more interconnected, a reliable method is needed for inter-ECU long-reach connections, especially for life-critical applications requiring high resolution, large amounts of data and split-second decisions. PCIe technology over cable is a viable, low latency, long-reach interface for in-vehicle ECU connectivity. For short reach applications within the ECU, retimers, redrivers and crosspoint/multiplexer (MUX) devices can increase link margin and further enhance PCB routing flexibility for system redundancy and fan-out distribution.
This webinar introduces the benefits of PCIe technology-based connectivity in automotive inter-ECU networks.
