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 Series in a three bank (156 pin) orientation for module stacking. Samtec specifically designed the QMS/QFS Series 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.

Samtec also offers precision machined standoffs to limit the impact of tolerance stack up issues in stackable embedded 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.
