I have been wanting to start tinkering with FPGA things again and have a Digilent Nexys 3 board from when I was in school. I really want to play around with high speed ADCs and DACs (~100 MSPS), and I was planning to make my own board and somehow connect it to the Digilent board.
I don't know enough about high speed signal routing to know whether or not this Digilent board will be okay. Can I use the PMOD connection points to do this? They also have a 40-pin VHDC connector on the board. Is this a better choice to use? Or if this board is not a good choice, can someone recommend an alternative?
