I'm working on a project to sample signal at 500MSPS with FPGA and ADC. Since I cannot design IC myself, I want to find one external ADC board that can be directly connected to my FPGA board. I have searched online and only found ADC board with FMC connector can work at 500MSPS or higher. The FPGA board I'm using is Digilent Anvyl Spartan-6 FPGA board and it doesn't have FMC connector.
I have finished previous project connecting this FPGA board with AD9226 via 2x20 pin connector working at 50MSPS. I don't have any budget for buying a new FPGA board so I hope I can continue using this same one.
Is there any solution for this without replacing the FPGA board? Could I find any ADC board which can work at 500MSPS with pin connector?
