+title: NVIDIA Tegra20 S/PDIF Controller
+
+description: |
+ The S/PDIF controller supports both input and output in serial audio
+ digital interface format. The input controller can digitally recover
+ a clock from the received stream. The S/PDIF controller is also used
+ to generate the embedded audio for HDMI output channel.
