A2B™ 2.0 Automotive Audio Bus Solutions

A2B 2.0 Automotive Audio Bus is the next evolution of ADI’s market-leading A2B technology, which builds upon the solid and trusted foundation delivered over the past decade by existing A2B 1.0 products. High performance, low latency, and simplicity of use remain core elements of the A2B 2.0 value proposition. At its core, A2B 2.0 remains an EMC-robust technology, designed specifically for automotive applications, that quadruples the available bus bandwidth (100 Mbps, full-duplex) to better address the expected transition to high definition audio in future car architectures. A2B 2.0 utilizes the exact same cable/connector infrastructure as A2B 1.0, allowing car OEMs to easily upgrade their car audio systems. Additionally, A2B 2.0 devices offer unparalleled integration, enabling up to 30% system cost reduction.

Value and Benefits

  • 4× Bandwidth Increase: A2B 2.0 delivers a 4× increase in bus bandwidth, supporting up to 119 up/down audio channels—enough for even the most advanced automotive audio systems.
  • Ethernet Tunneling via OASPI: Integrates an industry-standard Open Alliance SPI (OASPI) interface, enabling Ethernet data tunneling over the
    A2B 2.0 network for enhanced connectivity and flexibility.
  • Up to 30% System Cost Reduction: Achieves significant cost savings—up to 30% in locally powered systems—by increased functional integration and reduction of external eBOM components.
  • Maintains Low Latency & Simplicity: Preserves A2B technology’s hallmark low latency (62 μs) and ease of use, ensuring seamless integration and performance.
  • Comprehensive Development Support: Supported by a broad range of low cost evaluation boards and robust debug/emulator systems, streamlining development from concept to final validation.
