Tool/software:
Hello, experts.
Please tell me about the output of the clipped SINE waveform of the PCM1681 as soon as possible.
The figure below shows the circuit configuration and the observation waveform when the clipped SINE waveform is output from the FPGA.
At 1 kHz and 2 kHz, the waveform is output normally, but at 3 kHz, the waveform is not output properly.
The output data from the FPGA to the DAC is shown in the figure below.
The PCM1681 is the H/W control, LRCK = 16kHz, SCK = BCK = 4.096MHz (=256fs).
The LPF circuit is shown in the figure below.
Please tell me how to output from the PCM1681 according to the output waveform of the FPGA at 3kHz.
