OpenVPX VPX4840 and VPX4850 carrier card models provide a simple and cost-effective solution for interfacing XMC modules to a VPX computer system. Both products feature two XMC slots with support for front or rear panel I/O. Devices are available with VITA 42, VITA 61, or VITA 88 connectors to route power and interface bus signals to the plug-in mezzanine modules. Both models support a choice of direct PCIe connection to the VPX backplane via the data or expansion plane. The XMC sites have a 16-lane PCIe bus Gen A3 interface enabling rapid data throughput. By inserting XMC mezzanine modules on the carrier, including XMC processor (prXMC) modules, developers can now leverage hundreds of available function modules currently unavailable in a VPX platform.
