PCI/104-Express Standard Products and Support

PCI/104-Express Standard Products and Support

Overview

The PCI/104-Express™ specification establishes a standard to use a high speed PCI Express® bus in embedded applications. It was developed by the PC/104™ Embedded Consortium and adopted by member vote in March 2008. The PC/104™ Consortium chose PCI Express® because of its full PC market adoption, performance, scalability, and growing silicon availability worldwide. It provides a new high-performance physical interface while retaining software compatibility with existing PCI infrastructure.

Incorporating the PCI Express® bus within the industry proven PC/104™ architecture brings many advantages for embedded applications including fast data transfer, low cost due to the unique self-stacking bus of PC/104™, high reliability due to the inherent ruggedness of PC/104™, and long-term sustainability.

PCI/104-Express – Q2™ (QMS/QFS)

The PCI/104-Express™ standard specifies Samtec’s Q2™ QMS/QFS Products in a three bank (156 pin) orientation for module stacking. Samtec specifically designed the QMS/QFS Products with a 15.24 mm stack height for top and bottom board stacking. Q2™ has triple the wipe of many high speed mezzanine interconnects making it appropriate for rugged applications.

PCI/104-Express OneBank - Q2™ (QMS/QFS)

To offer system designers greater control over PCB real estate, the PC/104™ Consortium has developed PCI/104-Express™ OneBank. This new standard is an extension to PCI/104-Express™ and uses specialized single-bank Q2™ connectors which mate to the traditional 3-bank connectors. Now, engineers can win back valuable board-edge real estate by only bringing the vital main-bus to cards with OneBank connectors. They are available in both 15.24 mm and 22 mm stack heights.
