Hi ! I have a consult of my ADAU1701: it's possible to generate a sinus of 48 KHz, keeping the sample rate at 192KHz and the program length at 1x1024? Thanks.
No, that's not possible. In order to run the DSP at a sample rate of 192 kHz (4x the normal rate), the core can only process 1/4 of the number of instructions. This is because the DSP core frequency is fixed and it cannot speed up to accommodate a sample rate of 192 kHz while running the full program RAM.
