Introduction
The Teledyne LeCroy PCI Express
Gen4 M.2 MKey Interposer CrossSync Phy
, which is used with Summit T54 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 M.2 interposer 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 16.0 GT/s and link widths
of up to x2 or up to x4.
The interposer supports side band signals such as PERST#, WAKE#, CLKREQ# and SMBus (SMBCLK, SMBDAT).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 “B”, “M” or a “B/M” keyed memory SSD can then be connected to a host based B or 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.
