Does Cypress we have any solution for Uncompressed Digital Audio (such as 192KHz sampling PCM I2S format) to USB-C bridge?

For Type-C specification, it have defined Audio Adapter Accessory Mode in Section A. Analog audio headsets are supported by multiplexing four analog audio signals onto pins on the USB Type-C® connector when in the Audio Adapter Accessory Mode. The four analog audio signals are the same as those used by a traditional 3.5 mm headset jack. This makes it possible to use existing analog headsets with a 3.5 mm to USB Type-C adapter. The audio adapter architecture allows for an audio peripheral to provide up to 500 mA back to the system for charging.

If this is the one you are looking for, there no need any power delivery controller on the design. 

 

Best Regards,
