Beginning in 1988, the UNH-IOL has built a multimillion dollar facility testbed and developed testing solutions to help companies efficiently and cost effectively deliver products to market. UNH-IOL’s services fit the needs of the market, while maintaining broad, comprehensive interoperability and conformance testing of networking, data, telecommunications, and storage products. UNH-IOL’s extensive staff is directly involved with standards-bodies, and 100+ of its students are directly involved in interoperability testing and verification activities.
The A2B low-latency, digital audio bus transmits audio and control data together with clock and power over a single unshielded twisted pair cable. Its daisy-chain capability reduces cable weight and system complexity while improving fuel efficiency - making it particularly well suited for emerging wiring-intensive applications such as Road Noise Cancellation, Personal Audio Zones, and In-Car Communications.
"With over 30 OEMs having now committed to deploy A2B-based systems, we’re excited to see the launch of this critical test capability for A2B," says Ken Waurin, A2B marketing manager, Analog Devices. "Announcing the UNH-IOL as the first A2B Test Lab is a major milestone in the expansion of the A2B ecosystem. The lab's third-party testing helps ensure high quality products and provides more efficient system-level integration by our OEM, Tier 1, and third-party partners."
Working closely with Analog Devices, the UNH-IOL assisted in the development of the test service to validate A2B solutions coming from the company’s customers. By pre-testing devices to the A2B specification at the UNH-IOL, system manufacturers can ensure their products interoperate seamlessly with other A2B products used in an application. While the A2B technology was initially targeted towards automotive use cases, there is also a future for A2B in emerging consumer and and other technology segments.
“By providing a baseline for A2B conformance testing, automotive manufacturers and other A2B customers can save considerable effort in pre-screening solutions,” says Bob Noseworthy, principal engineer, UNH-IOL. “As the adoption of A2B solutions continues to grow, members will have confidence and assurance of functionality for their products.”
