5.13 How to connect the Audio Interface
The figure shows how to connect the module I2S interface to a low-power stereo codec, e.g. NXP SGTL5000, that includes headphones
and is designed to provide a comprehensive audio solution for portable products that require line-in, mic-in, line-out, headphone-out and
digital I/O.

WARNING!
To implement the SGTL5000 on the carrier board, remember to supply the VDD pin 30 of the SGTL5000 device by fixed voltage
as suggested to fix a silicon bug (for further detail refer to SGTL5000 data sheet)
