Intel® Display Audio Interface

The Intel® iDisp Audio link is a feature offering connection to the Intel® iDisp Audio codec. The Intel® iDisp Audio codec is used to provide audio streams routing to the integrated HDMI and DP links, through the existing Intel® HD Audio controller SW stacks. This iDisp audio codec used to be attached to the Intel® HD Audio link, however, it transitioned to a dedicated 3-wire iDisp Audio link to save pin counts on the compute tile, as well as providing finer grain power management to the audio link interfaces. The Intel® iDisp Audio codec is enumerated by the Intel® HD Audio driver software. Features for the Intel® HD Audio interface is provided below:

  • 1 SDI signal to support 1 iDisp audio codec
  • Drives 96 MHz frequency BCLK support
    • SDO single pumped to 96 Mb/s
    • SDI single pumped up to 96 Mb/s
  • Provides cadence for 44.1 kHz-based sample rate output.
