Introduction
The Teledyne LeCroy PCI Express 5.0 M.2 M-Key Interposer CrossSync PHY Capable, which is used with Summit T5
Protocol Analyzers, enables PCIe bus traffic between a system board or tablet and a M.2 connector on a PCIe M.2 device
to be monitored, captured, and recorded for protocol analysis. The Gen5 M.2 Interposer (CrossSync PHY capable) will
support analysis for PCIe host interfaces such as SATA Express (AHCI/PCIe) and NVM Express (NVMe) at data rates from
2.5 GT/s up to 32.0 GT/s and link widths of up to x2 or up to x4.
The interposer supports side band signals such as PERST#, WAKE#, CLKREQ#, SMBus (SMBCLK, SMBDAT) and analog
probing for PCIe high speed serial signals as well as probing/monitoring for power rails and reference clock. The M.2
technology specification includes two connector definitions: Socket 2 and Socket 3. Socket 2 keyed as "B" allows for PCIe
x2 interface for SSDs, WWAN or other non-storage devices. Socket 3 keyed as "M" is strictly for high-performance storage,
offering x4 lanes of bandwidth in this form factor. In some cases a "B/M" keyed SSD will also be available and it is both a
Socket 2 and 3 type. A, "M" or a "B/M" keyed memory SSD can then be connected to a host based M connector which is
capable of supporting any of the devices mentioned above.
Teledyne LeCroy provides an interposer to use with M and B-M type memory modules. The interposer supports the 30mm,
42mm, 60mm, 80mm, and 110mm SSD lengths as well as 22mm and 30mm widths. The interposer can be used with
Summit T4 Analyzers using a conversion cable.

- Page 2 If required, install a different extension bracket to the small PCB at the end of the 18" interposer cable. The extension brackets are provided to allow the user to attach and secure the Teledyne LeCroy M.2 interposer cable on the host system which usually supports different M.2 card form factors.
- Page 3 For this cable configuration screws are used to hold the bracket to the PC Board. The assembly process for swapping the default Type 2260 bracket with the Type 2280 is described below (follow the same steps for the Type 22110 bracket). 1.
- Page 4 Interposer DUT Standoff Installation A flexible attachment M.2 standoff assembly is provided for the different types of DUTs supported which are 2230, 2242, 3042, 2260, 2280, and 22110. Move the M.2 standoff based on the DUT Type. The standoff will be attached to 2280 location by default.

8. Power on the Analyzer and wait for it to be recognized by the application. Note: If prompted to update the firmware please do that before proceeding. 9. Power on the host machine. 10. Launch the Teledyne LeCroy software application to monitor, record and view PCI Express traffic passing through the M.2 Interposer. 11. Power on the system under test. - Page 6 Clock Configuration and Other Switch Settings SW1: A pushbutton SW1 is used to turn off the terminations and remove all loads on the unused interposer receivers depending on the maximum number of lanes to be analyzed. Press the pushbutton switch (SW3) to move to the next active width as indicated by the LEDs (next to the switch on the interposer.
