A²B 2.0, the latest version of Analog Devices’ Automotive Audio Bus technology, is officially available. It is designed for enhancing the in-car audio experience for automakers and tier one suppliers. A²B 2.0 offers greater bandwidth and Ethernet connectivity while retaining the low latency and simple design features that have been inherent to A²B for more than a decade now. The A²B technology has already been deployed in over 35 automakers worldwide, with hundreds of millions of nodes used, making it a proven basis for future improvements.
For Low Latency Automotive Applications :
A²B technology is tailored for applications that demand low-latency performance with deterministic results. This makes it easier for the system to perform advanced operations such as road noise cancellation and in-car communication systems through a low-cost daisy chain design, which reduces wiring costs and complexities by up to 75% and saves significant development time for automakers. The increasing popularity of A²B is made possible by a robust ecosystem comprising OEMs, silicon partners, and ODMs, along with powerful software development kits and testing facilities.
Move to software-defined vehicle architecture :
The move to software-defined vehicle architectures results in an increase in the need for high-bandwidth and deterministic connectivity along with in-car technologies that depend heavily on software upgrades. This move highlights the need for enhanced audio and infotainment systems, indicating the adoption of premium in-car technology that works well with modern car networks.
Better performance and efficiency :
“Audio plays a pivotal role in shaping the driver’s experience of refinement, safety, and responsiveness inside the car, particularly in the context of software-defined cabins,” stated Yasmine King, Corporate Vice President, Head of Automotive Business Unit, ADI. “In this age, audio connectivity that can be integrated seamlessly into the overall network of the car becomes a critical need. A²B 2.0 offers higher bandwidth, lower latency, and Ethernet tunnelling without making the design complex.”
