PCM4204: Power On Reset Sequence

Part Number: PCM4204
Other Parts Discussed in Thread: PCM4202,

Hi Team,

My customer encountered a rare problem. The PCM4202 does not work normally at startup ( noise output). When the reset time is extended, the probability of failure will be reduced. Now the reset time of PCM4202 has been  extended to 2 seconds when starting up, but it still occurs occasionally.

What are the requirements for the power on Reset Sequence of the pcm4204?

Best regards,
