5  General Description 

The RTM311 is a 3U VPX Rear Transition Module. It is intended to be used in combination with 
certain 

4DSP’s Xilinx FPGA VPX boards, typically VP881. The board implements features that 

are required to bring several interfaces of a VPX board to the rear panel. Some of those interfaces 
are: USB2.0, USB3.0, DisplayPort, Gigabit Ethernet and SD card. The board also carries a M.2 
SSD card that communicates to the VPX through SATA or PCIe.  

The global architecture of the RTM311 is shown in Figure 1.
