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.
