I am using fmcomms3 with zedboard (no-os).
IN the TX channel, there are 2 signals dac_clk and dac_valid.
1. Is the symbol rate determined by dac_valid? So if my dac_clk is 100mhz and dac_valid pulses once every 2 dac_clk cycles, my sample rate is 50MS/s?
2. What happens if dac_valid is constantly high or low but with dac_clk running. Will data still be transferred from the BBP to the ad9361?
