PCI Express 6.0 and CXL Interposer

24 February 2023 – Teledyne LeCroy announced availability of their PCI Express (PCIe) 6.0 CEM x16 interposer for probing systems and devices that use the latest PCIe 6.0 and CXL specifications. This new interposer takes advantage of Teledyne LeCroy’s TAP6 technology and will benefit the development and test community by reducing signal integrity issues as they push the limits of the specification where signal loss budgets become crucial.

Upcoming PCIe 6.0 and CXL systems and devices will enable data-intensive applications in the cloud and data center, as well as artificial intelligence, machine learning, automotive, and IoT (internet of things). The PCIe 6.0 specification doubles the bandwidth of the current PCIe 5.0 systems. Teledyne LeCroy’s PCIe 6.0 CEM x16 interposer provides greater sensitivity to capture PCIe 5.0 traffic today, making it possible to tap higher data rates in difficult environments, and is also designed to capture PCIe 6.0 protocol traffic that is based on PAM4 (4-level Pulse Amplitude Modulation) signaling.

The new PCIe 6.0 CEM x16 Interposer supports data rates of 2.5, 5.0, 8.0, 16.0, 32.0, and 64.0 GT/s with up to x16 link widths. It provides a simple and easy way to probe PCIe traffic between a host and PCIe add-in card. In combination with Teledyne LeCroy’s Summit family of PCI Express 5.0 protocol analyzers, the new PCIe 6.0 CEM x16 interposer currently enables engineers to test product designs based on PCIe 6.0 technology up to 32 GT/s and will work in combination with a PCIe 6.0 capable Summit protocol analyzer to support full 64 GT/s speeds when that analyzer is released in the future.

“We expect that test and development teams will appreciate using this highly precise probe to support their current protocol testing requirements while also preparing for future PCIe 6.0 test requirements”, said Joe Mendolia, vice-president of marketing at Teledyne LeCroy. “PCIe 6.0 is important to our customers and Teledyne LeCroy is committed to providing the best in high-speed protocol analytics and the broadest array of features available in the market”.
