MIPI® SoundWire* Interface

The SoundWire interface is a feature offering connection to the SoundWire devices, which include audio codecs and modem codecs. The SoundWire interface is the latest audio interface targeting (but not limited to) the phone and tablet market and the main advantage is the connection simplicity with a two wires multi-drop topology and PDM streaming capabilities. SoundWire device class initiative for audio is bringing standardization to the audio codec SW stack. These devices are enumerated based on vendor / device ID of the SoundWire device reporting, allowing vendor customization of audio codec SW if desired. SoundWire interface capabilities are listed as follows:

  • Up to 4 SoundWire interfaces frame rate synchronized on global periodic events
  • SNDW[0] supports 4 data lane per SoundWire interface
  • Support SoundWire Device Class Specification for Audio Controls and Memories
  • Up to 8 PCM bidirectional streams per SoundWire interface
    • Direction is programmable as either input or output stream
  • Up to 8 channels per PCM streams
  • Interrupt / PME wake capable on DATA pin assertion in low power state
Note:PDM support exists in design but is not enabled for SNDW links.
