XMC Products

WOLF develops XMC (Switched Mezzanine Card) graphics cards for video capture, process, encode and display. WOLF XMC video graphics boards can include an embedded NVIDIA GPU and/or Xilinx FPGA. Rugged air cooled and conduction cooled options are available for WOLF's XMC modules.

 

WOLF can provide support for virtually any video signal including 12/6/3G-SDI, CoaXPress, ARINC 818-2/3, STANAG-3350 A/B/C, CVBS, RS170, RS343, LVDS, DVI, DisplayPort, Camera/Channel Link, and custom. Contact us to discuss your specific requirements.

XMC Information

Rugged WOLF XMC video graphics cards

The XMC mezzanine format defined in VITA 42 is an evolution of the previous PMC (PCI mezzanine card) format. The XMC specification extends PMC with the addition of new connectors which support gigabit serial interfaces plus alternative I/O standards. 

The theoretical maximum power available on an XMC module is 100W. However, practical considerations normally require a lower XMC maximum operating power, with 25W being a typical maximum operating power for legacy implementations, with higher operating power often permitted by newer system designs.

The XMC connector is a pin-socket connector with 114 pins arranged in a 6 x 19 array. A single-width XMC module can have one or two 114 pin connectors (P15 and P16). It can optionally include PMC connectors (P11 to P14) for legacy compatibility. Standard XMC dimensions are 74mm by 149mm. There are also provisions for a shortened depth card layout, with 124 to 139mm depths.

  

The primary XMC connector (P15) is reserved for serial links, power, and other pre-defined functions. The secondary XMC connector (P16) provides user-defined pins which can include video I/O.

XMC 1.0 connectors are defined in the VITA 42.0 XMC baseline specification.
XMC 2.0 connectors are defined in VITA 61.
XMC+ connectors are defined in VITA 88. 

  • The XMC 1.0, 2.0 and XMC+ connectors use the same footprint but are not intermateable.
  • The XMC 2.0 connector was designed to be more rugged compared to the XMC 1.0 connector, and it has been electrically characterized to support higher frequencies (and therefore, higher data throughputs).
  • The XMC 2.0 connector is an off-white color, to make it easy to visually differentiate it from the black XMC 1.0 connector.
  • The standard stacking height of an XMC 1.0 connector is 10mm (allowing it to fit on a carrier board with a slot pitch of 0.8 inch) or 12 mm (allowing it to fit on a carrier board with a slot pitch of 1.0 inch).
  • The XMC 2.0 connector can use the same stacking height as XMC 1.0 (10mm or 12mm) or can use a 15mm or 18mm stack height.
  • The XMC+ connector has been electrically characterized to support higher frequencies (and therefore, data throughputs) compared to the XMC 2.0 connector.
  • XMC Connector Update in ANSI/VITA 42.0-2021: The 2021 revision of the standard removed the recommendation of one connector solution over the other. In the 2021 revision of the standard, the XMC 2.0 and XMC+ connectors are listed as "alternative" solutions to the XMC 1.0 connector. The XMC 1.0 connector is now listed as supporting up to PCIe Gen4 data rates (previously only Gen2).


PCIe Transfer Rate, Throughput, and XMC Support

  x8   2.0   4.0   7.88  15.75   31.508

* Transfer rate is in giga transfers per second (GT/s) and it includes the overhead transfers used for encoding. The overhead transfers do not provide Throughput.
** Throughput indicates the data transfer speed without the encoding overhead. For example, PCIe 1.0 uses an encoding scheme with a 20% overhead. That means a transfer rate of 2.5 GT/s provides 80% of that in throughput, that is 2.0 Gbits/s of data throughput, or 0.25 GBytes/s of data throughput.
