5.11 How to connect the Audio Interface
The evaluation board is equipped with the low-power stereo codec, 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.
The figure shows how the device interface is connected to the module using the I2S BUS

WARNING!
To implement the SGTL5000 on the carrier board, remember to connect the VDD, pin 30 of the SGTL5000 device, to +1V8 to fix
a silicon bug (for further detail refer to SGTL5000 data sheet)
