Low-cost AVB Audio Endpoint Kit


  • Audio Video Bridging (IEEE 802.1 AVB and IEEE 1722) provides transport for AV streams across mixed-use networks with a very high quality of service. With the rapid growth in adoption of AVB for audio transport, audio endpoint solutions must be low cost and production ready.
  • XMOS and Attero Tech have jointly developed a solution consisting of the flexible XMOS software-only implementation of AVB audio and a low-cost board supporting up to 8 duplex channels of audio.



  • 16-core XS1-L2 device
  • Stereo analog audio in/out via 3.5mm jack or RCA sockets
  • Up to 8 channels via I2S headers
  • High quality clock recovery with PLL
  • GP-IO for buttons/LEDs
  • Expansion header with 12 spare I/O available
