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.

Specifies whether board prefers parent clock to stay at a fixed rate.
This allows multiple Tegra20 audio components work simultaneously by
limiting number of supportable audio rates.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
