Audio Video Bridging (IEEE 802.1 AVB and IEEE 1722/1733) provides transport for AV streams across mixed use networks with a very high quality of service. XMOS has developed a flexible, software-only implementation of AVB audio which is configurable to support a simple stereo pair to over a 100 audio channels over Ethernet. The deterministic architecture of XMOS devices is a perfect match for the low latency, time synchronized nature of AVB. XMOS devices also provide the ability to integrate digital audio interfacing, control functionality using TCP/IP and DSP processing often required in AVB endpoints.

Development Kits
XMOS offers a range hardware options for the evaluation and development of products based on our AVB audio reference design software. The table below outlines common configurations:
| Configuration | Kits |
| Single 100Mb endpoint with basic clock recovery and stereo analog out/in via 3.5mm jacks | XS1-G Development Kit (XDK) |
| Single 100Mb endpoint with high quality clock recovery using a PLL, 8ch out/6ch in analog via 3.5mm jacks and S/PDIF out/in | XS1-G Development Kit (XDK) XAI Multichannel Audio Interface |
| Four 100Mb endpoints each with high quality clock recovery using a PLL, 8ch out/6ch in analog via 3.5mm jacks with S/PDIF out/in | AVB Audio Development Kit (provides 4 x XDKs) XAI Multichannel Audio Interface x 4 |
| Single 100Mb endpoint with 0.1†headers for user connection to CODEC via I2S/I2C and optional external PLL for improved clock quality | XC-2 Ethernet Kit |
| Single 100Mb endpoint with two ports (supporting a daisy chain topology) with headers for user connection to CODEC via I2S/I2C and optional PLL for improved clock quality | XC-3 Ethernet Kit |
| Single 1Gbit endpoint with high quality clock recovery using a PLL, 8ch out/6ch out analog via 3.5mm jacks with S/PDIF out/in | Please contact XMOS |
