USA: Analog Devices Inc. has introduced a digital audio bus technology capable of distributing audio and control data together with clock and power over a single, unshielded twisted-pair wire.
The AD2410 transceiver is the first in a family of devices that enables ADI’s new Automotive Audio Bus (A²B), which significantly reduces the weight of existing cable harnesses, resulting in improved vehicle fuel efficiency while delivering high fidelity audio. The AD2410 transceiver also eliminates the need for expensive microcontrollers with large memories that are required in existing digital bus architectures.
“As an early implementer of ADI’s A²B, Panasonic Automotive found the technology to significantly reduce cabling complexity and associated cost and weight of next-generation infotainment systems, key areas of focus for Panasonic’s OEM customers,” said Jonathan Lane, Group manager, Audio & Acoustics, part of Panasonic Automotive Systems Co. of America (PASA) Advanced Development Engineering.
“We believe A²B to be well suited to address applications such as microphone arrays and Active Noise Cancellation, a leading area of expertise for Panasonic that we expect to be an integral component of next-generation infotainment systems.”
