General Information
The VPX4812A 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 VPX4812A provides support for Rear I/O connections from the XMC P16 connector. The
TRANS-V112 is a development Rear Transition Module for the VPX4812A used to bring out Rear
I/O connections through the backplane.
The VPX4812A supports up to four VPX Fat Pipe (x4) connections to other cards in the system at
Gen 2.0 speeds. The VPX4812A 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 VPX4812A also provides support for a VPX Double Fat Pipe (x8) connection to an XMC card
at Gen 2.0 speeds.
The VPX4814A disconnects the PCIe connection on the fourth bottom-most Fat Pipe of P1
allowing it to be used in systems with an Ethernet control plane interface. This provides the
VPX4814A with the ability to be used as an XMC Carrier Card in the majority of the standard
OpenVPX profiles.
The information and features for the VPX4812A listed in this manual are also applicable to the
VPX4814A model with the exception of the PCIe connection noted previously.
