Hi support person,

I purchased an Evaluation ADAU1772 board for my project.

All I would like to do is convert I2S to PDM output.

ADAU1772 is I2S master in this configuration. Please refer to the attachments for the settings in SigmaStudio App

Observations:

1.The BCLK from ADAU1772 is alway 48Khz regardless wnat I select in "Serial Port FS" section

2. The PDM Output is always there even when disconnecting the I2S source

I'm not sure what I might have missed. Your prompt response is greatly appreciated.

Best regards,

Bob Ngo
