XMOS/AT AVB Module Overview

XMOS AVB Module thumbnail
  • SUMMARY - 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.
  • DOCUMENTATION - Reference board kits have implementation guides, board schematics, PCB layouts and a BOM, so you have a solid footing for adapting the XMOS AVB Module to your application.
  • Reference Design - A fully functional board, tested and ready to go. All you need is a network switch and you're ready to send 16-bit, 48kHz audio over CAT-5 in both directions. How easy is that?


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.


  • XS1-L2 device for low cost
  • Stereo analog audio in/out via 3.5mm jack or RCA sockets
  • Up to 8 channels via I2S headers
  • Simple sample rate conversion to local clock or high quality clock recovery with PLL
  • GP-IO for buttons/LEDs
  • Expansion header with 12 spare I/O available
