See diagram below. On page 70 of the datasheet, it states that there is logic "FROM LMFC SYNC" that enables the data into the datapath. How do I know the value that goes in to the mux? Is there a register I read? A combination of registers? Is there somewhere in the datasheet that explains this but I have missed it?
I'm searching for reasons why my DAC is not outputting any RF even though it seems the part is correctly configured and I am transmitting data from the FPGA.
