General Information
The VPX4812 is an XMC Carrier Card Module in the 3U VPX form factor, targeted for processing,
communications, and display applications in the commercial, military, and aerospace markets.
The VPX4812 provides support for Rear I/O connections from the XMC P16 connector. The
TRANS-V112 is the Rear Transition Module for the VPX4812 used to bring out Rear I/O
connections through the backplane.
The VPX4812 supports up to four VPX Fat Pipe (x4) connections to other cards in the system at
Gen 2.0 speeds. The VPX4812 can be used as a switch card allowing an upstream Fat Pipe or
Double Fan Pipe connection
–
typically to a CPU
–
to communicate with up to three downstream
Fat Pipe connections or a single Double Fat Pipe connection.
The VPX4812 also provides support for a VPX Double Fat Pipe (x8) connection to an XMC card at
Gen 2.0 speeds.
The VPX4814 disconnects the PCIe connection to the third downstream card allowing it to be
used in systems with an Ethernet control plane interface. This provides the VPX4814 with the
ability to be used as an XMC Carrier Card in the majority of the standard OpenVPX profiles.
