Hello experts,
My customer is using PCM1754 and have pop noise trouble.
With refereeing some thread about PCM1754 pop noise, customer tried setting MUTE low before stopping CLK to prevent pop noise, but result is not well.
Attached file is waveform about DAC output and CLK and MUTE. There is pop noise even if MUTE become low before stopping CLK.
Could you give us advice how to prevent pop noise?
