XMC Overview

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, AMD GPU and/or Xilinx FPGA.

Rugged air cooled and conduction cooled options are available for WOLF's XMC modules.

Rugged WOLF XMC video graphics cards

The XMC mezzanine format 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 XMC connector is a pin-socket connector with 114 pins arranged in a 6 x 9 array. A single-width XMC module can have one or two 114 pin connectors.

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 is defined by VITA 42 while XMC 2.0 is defined by VITA 61. The main difference between XMC 1.0 and 2.0 is the type of connector used on the board.

  • The XMC 1.0 and 2.0 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.
  • The XMC 1.0 and 2.0 connectors support different clock speeds (and therefore, data throughputs).  

XMC 1.0 has been electrically characterized to support 3.125 GHz and provides support for PCIe 1.0.

XMC 2.0 has been electrically characterized to support 5+ GHz allowing protocols such as PCI Express 2.0.

PCIe Clock Speeds and Throughput

   Total Lanes   PCIe 1.0   PCIe 2.0   PCIe 3.0 
 Clock (GHz)      2.5   5.0   8.0

 Full Duplex
 Peak Data
 Transfer Rates (GB/s)   

  x1   0.5   1.0   1.97
  x4   2.0   4.0   7.88
  x8   4.0   8.0   15.75

PCIe 1.0 and 2.0 uses an 8b/10b encoding scheme, resulting in a 20% (= 2/10) overhead on the raw channel bandwidth.
PCIe 3.0 uses a 128b/130b encoding scheme, resulting in a 1.54% (= 2/130) overhead on the raw channel bandwidth.
