The ADC-VPX3-XMC-RTM is a 3U, VPX, Rear Transition Module (RTM) designed to interface with Alpha Data VPX products.

The RTM provides complete breakout of all backplane signals providing the user with complete flexibility during development and debug. A PCIe Re-driver allows for PCIe interface in the data plane from a host PC with a PCIe cable breakout. Two zQSFP cages give high density HSSIO on the openVPX data and expansion planes. Two SFP cages give easy access to the two openVPX control planes. ATX Power connector with integrated current monitoring provides real time feedback of current draws on each power rail. Header pins provide easy access to all other general purpose IO.
