Typical Application (continued)

9.2.2 Detailed Design Procedure

•

Hardware control with GPIO of microcontroller

•

Select crystal capacitors by reading the crystal data sheet

•

Select if system will be run off the recovered clock or the external crystal by setting CKSEL high for the

external crystal and low for the recovered clock

•

Decide sampling rate and audio related settings

•

Configure microcontroller to receive PCM data along with User and Channel data from S/PDIF or AES/EBU

data stream
