Sorry, I need to fish through more datasheets, but quickly looking at diagrams of the FMCOMMS3-EBZ to FPGA reference builds, it looks like the A/D function is straight from the AD9361 to the FPGA for 12 bit samples. I don't see where/how the AD7291 comes into play in the signal RF to Digital chain? I just see that it provides the temperature of chip...
What role does the AD7291 play on this board, where should I be looking to understand this.
THANKS!
