Hi,
Below shows the normal floor noise and output signal of DAC3482 in this board.
But sometimes after power-up of the board, the floor noise of DAC3482 is much bigger and there is many spurs near the output signal. When this happens, it can be solved by tuning Reg_0x24. Could you pls suggest any method that I can try to avoid this issue? What is the possible root cause of this issue? There is another DAC3482 with same schematic and register setting in this system which is programmed later after power-on. I didn't find the same issue in this later one.
Thanks.
