This card is XMC or alternatively PMC extension Card for 3U cPCI computer systems. This card provides an easy and low cost solution that enables use of a PMC mezzanine I/O card or an XMC card in a Standard 3U cPCI computer system. The carrier card acts either as an adapter to route PCI bus signals to and from the PMC card through the cPCI card slot connector or an XMC.3 card adapter, which allows up to 4 lanes PCI Express XMC card to be used in a cPCI card slot connector. The XMC card is VITA 42.3 compatible and supports X4 PCI Express lanes. The PCI Express interface supports 1 or 4 lanes to the XMC card XMC cards add two high-density, high-speed connectors designated J15 (primary) and J16 (secondary). Each connector contains 114 pins. On the J15 primary connector, high-speed differential Tx/Rx signals, along with 3.3V power, ground, I2C, JTAG, reset and presence signals. On the J16 secondary connector, 20 high-speed differential pairs are defined, along with grounds and 38 user-defined pins for additional I/O.

The XMC Card is completely transparent to all cPCI operations through a PCI to PCI express bridge (PLX-PEX8114). The bridge enumerates as a standard PCI device and provides direct transparent accesses to the XMC card. The simple two port device is equipped with a standard PCI Express port that scales X1, X2, or X4 lanes in width giving an effective bit rate scaling from 2.5 to 10Gbps. LED lane indicators provide lane status during operation. The XMC card supports PCI Express link with four lanes on primary XMC connector and IOs on secondary XMC Connector. The board detects automatically whether an XMC or a PMC is plugged through present LED indicators. The PMC slot can be used for 32/64 bit and 33/66 MHz PMC cards. The combination carrier plus PMC card enables the integrator to build modular systems based on a variety of off-the-shelf standard PMC boards. Field I/O signals are routed through the carrier cards rear J2 connector. Refer to the Rear and front panel options for PMC card. The voltage keying for cPCI carrier and its PMC site is 3.3V.

This card is available in Air-Cooled and Conduction-Cooled version. The conduction-cooled version of the cPCI carrier card addresses the needs of aerospace, military and rugged applications. It contains a thermal heat frame. An aluminum ring or plate can fit together with conduction-cooled PMC cards. Conduction cooling conducts heat away from the hot spots of the board and transfers the heat to the card edges and to the system chassis. No active ventilation is necessary inside the system, which means the boards are sealed from the environmental influences found outside of the chassis. This unit is ideal for airborne systems, deployment in battleground equipment, and other situations with advanced thermal management requirements. This conduction-cooled carrier card interfaces a PMC card to a cPCI computer system. The conduction-cooled version does not include a standard front panel. Only air-cooled version includes a standard front panel. The card is optionally available with a conformal coating layer.
