CM870 – 3U PMC/XMC Carrier VPX Board

As the processing power of SBCs continues to increase, expanding system functionality by means of
PCI Mezzanine Cards (PMCs) and Switched Mezzanine Cards (XMCs) is frequently the method of
choice for maximizing performance while minimizing system size, power consumption, and cost.

To facilitate expandability beyond the PMC/XMC sites on 3U VPX SBCs, Aitech has developed the
CM870 PMC/XMC Carrier. The CM870 provides an additional active interface between the 3U VPX
backplane and a PMC/XMC, for each available 3U VPX backplane slot. Four PCIe x4 (four lane) links
are routed to the VPX backplane connector to enable fast connection with the processor board over
the switch fabric in OpenVPX systems.

In addition, CM870 can operate as a 4 port VPX switch supporting up to 4 VPX PCIe agents (slots).
Designed for harsh environment applications, the CM870 is available in commercial and rugged
air-cooled or conduction-cooled configurations.

With its low power consumption, the CM870 expands capabilities while consuming minimum resources.
