I programmed Spartan chip to produce serial data ( main_Clock, Data Clock, Data and Tag ) stream for a DAC. I need to make this system work with out wires. The main clock is 3MHz, Data clock is 1.5MHz. Can anybody advice me how to make it digital wireless ( Transmitter plus receiver). I have not done anything like this before. The DAC will be at 6 feet away from the Spartan chip.
