Does anyone know of a relatively inexpensive (<$150 USD) FPGA board meant to be socketed into a larger board that has the LVDS pins broken out? The CMODs from Digilent would be ideal if they had diff pair routing and the banks were powered appropriately. I would be happy with any mid-range FPGA — Spartan-7, Artix-7, or ECP5. I want to design a board with a high speed DAC and ADC but would rather avoid the task of doing layout and soldering for such a complex device.
