7.9.3 User FPGA Pinning
Each ADC is connected to the User FPGA (Kintex-7) via a dedicated serial clocked Interface. Each ADC
device has one input clock, one output clock and one conversion signal. For each ADC channel there is a
respective data output line, so both ADC channel transfers data at the same time.
