There are two options. Firstly, ADI offers an FMC interposer card that mates up
with the AD9250 ADC eval board. This board translates the pin assignments to
the FMC so that electrically it can be interfaced to certain FPGA development
kits. More information about which development kit and the specific details of
the FMC pin assignments is available on the interposer product page.
Secondly, there is a default FMC prototyping board, model AD9250-FMC-250EBZ,
that contains two AD9250 ICs, for four channels of data conversion. This board
connects directly to the Xilinx Kintex 7 development platform. Downloadable
resources for this board can be found on its wiki page.
