Hi Haury,

I think the image may be too low resolution, I do not see the distortion you are talking about. Can you describe it?

Regards,

Ben

Hi Haury,

Thank you. I have moved the thread to public. I also edited the block diagram you posted to exclude NDA material so I could post it to public (removed SER part number).
