Hi Maria, glad to be helpfull, However I have to suggest you to review what I said, and what I will to say, in a thorough manner because all I know is due to experiments and study of the code, so it can be simply wrong or inaccurate.
>From the x300.v file I'm reading (version UHD-3.15) the radio_clock is 200MHz and, probably, it is used in order to read data from the ADCs that are capable of 200Msps on a X310 (so between ADC and fpga the max throuput should 200Msps). The bus_clk should be 187.5 MHz, however in order to compare the throughput with the one from ce_clk you must take into account that in the bus_clk domain data are transferred at 64-bit word, while in the ce_clk domain words are 32-bit in size (a sample is 32-bit).
