My customer uses SSM2603 in their system and they have some issue at recording mode.

When they use a recording mode of SSM2603 , they get some noise sound.

Please refer attached noise sound file "noise" from them.


For your reference, I also attached their schematic file "SSM2603_AUDIO_SCH.pdf"

and block diagram file "BlockDiagram_Reg.pdf"  with register setting values.

And also I attached file with output wave form of I2S "I2S_WAVE.PPTX".


Q1) Would you confirm this issue and suggest how to solve this issue?

    (  If you have any opinions,  please let me know.)


Q2) And would you confirm their schematic, register setting values and output wave form of I2S?


Please confirm this issue and let me know your advices ASAP.
