Teledyne LeCroy’s U.2 (previously known as SFF-8639) adapter cards provide developers with extremely versatile tools to speed development of new U.2 designs and to trouble-shoot existing U.2 issues. Simply by plugging the U.2 device into the adapter, the engineer can then install the device into a standard PCI Express card slot and exercise all PCIe functions on the device. This allows engineers to quickly focus on trouble spots without the need for additional test equipment. Two configurations are provided: one for single-port devices and Port A of dual-port designs; and the second for Port B of dual-port designs. If more detailed information is needed, the adapters can be used with a standard PCIe interposer and Teledyne LeCroy analyzer to capture all PCIe data traffic passing through the interface, allowing engineers visibility to virtually all types of protocol problems that may affect device performance or reliability. Rapid identification of problems leads to rapid solutions, allowing faster time-to-market for new devices and quicker solutions to problems showing up on existing devices. In addition, if an U.2 port is available, Teledyne LeCroy offers specialty interposers designed for 2.5” or 3” devices that can be used as a direct traffic probe and analysis tool with any of our Summit™ product family of analyzers. In combination, these products provide flexible and powerful tools for developers working on U.2 designs to streamline testing and reduce time-to-market for new U.2 products.

U.2 Adapter Interconnection Overview
An appropriate interposer for an analyzer connection may be inserted at either location marked with this symbol. The interposer may be a specialty SFF-8639 Interposer (PE081UIA-X) inserted between the DUT and the SFF connector on the adapter, or may be a standard PCIe Interposer (e.g., PE041UIA-X) inserted between the PCIe slot connector on the adapter and the host PCIe slot. In either case, this will provide a means for the SFF-8639 DUT to be connected to a PCIe host slot while still providing a means for a Teledyne LeCroy analyzer to capture, decode and display the data traffic from host to device (see illustration below).
12V DC Power Supply (included)
Control Switches These control switches allow the user to specify the maximum lane width to be used (x1 or x4), and to specify the type and source of power supplied to the DUT (3.3V from the PCIe bus or 5V from the external DC supply; and 12V from the PCIe bus or 12V from the external DC supply).
x4 PCIe Slot Connector
Host PCIe Slot x4 or larger
The optional use of an interposer and analyzer in either location indicated allows all PCIe data traffic to be captured, decoded and displayed. This allows more detailed analysis of issues and faster solutions for protocol problems.
