Features & Applications

The low-cost AVB Audio Endpoint Reference Design includes all of the necessary hardware and firmware to help get your AVB audio endpoint up and running quickly. In addition, a PC/Windows hosted configuration utility is available to allow stream configuration and setup.

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. The low-cost XCore® XS1-L2 dual-core processor is at the heart of the new, commercial-grade reference design and reduces the cost for AVB endpoints by over 50% compared to alternative solutions.
