PCI/104-Express™ Embedded PC ModulesThe 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 low term sustainability. 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 mating connector sets, based on 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. The mating Q2 connector sets designed for PCI/104 Express applications are:
- ASP-129637-03 – 3 bank assembly, top (15.24mm)
- ASP-129646-03 – 3 bank assembly, bottom (15.24mm)
- ASP-142781-03 – 3 bank assembly, top (22.00mm)
PCI/104-Express™ OneBankTo 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 (52 pin) 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.
- ASP-129637-13 – 1 bank assembly, top (15.24mm)
- ASP-129646-22 – 1 bank assembly, bottom (15.24mm)
- ASP-142781-07 – 1 bank assembly, top (22mm)
