3.1.1.6 FMC+ Adapter Board Setup

The FMC+ adapter board interfaces with ADC12DJ3200EVMCVAL EVM and TSW14J57EVM to pass through the data lanes and has connections to take FPGA clocks, FPGA SYSREFs, and SYNC from the TIDA-010191 clocking board or ADC12DJ3200EVMCVAL EVM. Follow the schematic in Figure 3-2 to connect the FPGA clocks and SYSREFs from the clocking board.
