ADC+FPGA+DAC setup for predistortion

Hi, I am looking to buy the ADC12J4000EVM and DAC38J84EVM from TI. Both have an FMC connector and JESD204B interface. I am looking for a setup for predistortion and I would like to if there are...

Hi Rosanah,

Do you know how to connect the two TSW14J56EVMs? I would need the two to communicate to solve for predistortion coefficients and apply them.

Your question is not very clear. Could you please clarify?

The two FPGA EVMs do not need to communicate with each other.

The ADC and DAC boards would plug into their respective FPGA boards, and you would configure the JESD204B link between the FPGA and its respective FMC board. You would then connect the ADC to DAC using an RF cable.

If you wanted to change the characteristics of the RF transmit signal, then you would simply communicate from your PC to the DAC board, and likewise, if you wanted to change the characteristics of the RF receive signal processing, then you would simply communicate from your PC to the ADC board.

There is no way for the two boards to communicate directly.

Cheers,

Dave
