Industry First Protocol Test Solution for Next-Generation USB4? version 2.0 specification
Teledyne LeCroy’s Voyager M480x supports PAM3, Tunneled DisplayPort 2.1, and USB3 Gen T
Milpitas, CA, March 12th, 2025 – Teledyne LeCroy, Inc., a worldwide leader in USB protocol test solutions, is pleased to announce general market availability of Voyager M480x Protocol Analyzer, the first protocol analysis system for testing next-generation USB4® 80Gbps interfaces. This flagship solution is designed to address the entire development lifecycle including functional verification, qualification, and compliance testing.
The updated USB4® version 2.0 specification doubles the data transfer rate of today’s USB4 to enable higher throughput displays, storage, and USB-based hubs and docks. Aligned with the DisplayPort 2.1 standard, the USB4 version 2.0 specification supports tunneling of ultra-high bit rate (UHBR) video for higher resolution monitors. It also features USB3 Gen T support which, among other things, enables USB 3.2 applications to take advantage of USB4 throughput. These additions to the USB4 technology introduce a new level of complexity related to signal integrity, increased channel loss, new error correction mechanisms and backwards compatibility for design and test engineers that need to validate their products.
"USB-IF is pleased to acknowledge the launch of Teledyne LeCroy’s protocol analyzer for the USB4® Version 2.0 specification," said USB-IF President and COO Jeff Ravencraft. "The availability of protocol and compliance test equipment is essential to driving industry adoption, advancing USB innovation, and ensuring USB products continue to deliver the high performance and reliability users expect. USB-IF values Teledyne LeCroy’s continued contributions to the USB ecosystem and its commitment to advancing USB technology.”
“Teledyne LeCroy’s technical expertise in high-speed serial protocols has made our USB analyzers the #1 solution in USB protocol test for more than two decades and this commitment and leadership is on full display with today’s release of the Voyager M480x”, said Joe Mendolia, vice-president of marketing at Teledyne LeCroy’s Protocol Solutions Group. “The Voyager M480x analyzer supports full capture of up to 80Gbps transfer rate, and verifies additional enhancements in the USB4 specification, including tunneled DisplayPort 2.1, and USB3 Gen T protocol. Its flexible architecture offers optional 80Gbps traffic generation and compliance testing. For these reasons, the Voyager M480x is the intelligent choice for USB protocol testing over the next decade”.
About the Voyager M480x Protocol Analyzer
The Voyager M480x Protocol Analysis system leverages Teledyne LeCroy's cutting-edge T.A.P.6™ passive probe technology allowing accurate capture of the new PAM3 based signaling which is the foundation of the USB4 version 2.0 specification. The Voyager M480x provides an extensible architecture to allow the addition of traffic generation and compliance test capabilities for USB4 80Gbps in the future. Fully backward compatible with legacy Gen 3, Gen 2 and Gen 1 USB links, the Voyager M480x can seamlessly address the past, present, and future of USB protocol testing. The Voyager M480x works with industry standard USB Protocol Suite software that features a hierarchical display, real-time statistics, protocol traffic summaries, detailed error reports, powerful scripting, and the ability to create user-defined test reports, which allow developers to troubleshoot intricate problems and finish their projects on time. While offering support for prior generations of USB, the software now includes full decoding and analysis of both tunneled PCI Express version 4.0 and DisplayPort 2.1, as well as USB Gen T protocol decoding.
