Hello, I'm using AD9957 evaluation board. I use MATLAB to generate data, and load it into FIFO by evaluation board software, then the data will be transmitted to the AD9957. Evaluation board user guide mentioned:FIFO capacity is 65KB.I firstly thought FIFO can only load 65KB data each time. However, when I was doing the hardware testing, the txt data files generated by MATLAB have been more than 65KB, the oscilloscope is still display the modulation waveform exactly. why is it? Note: the FIFO window select the loop transfer option.
