+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.
