The AD2410 transceiver from Analog Devices, Inc. (ADI)
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. In addition, the AD2410
transceiver also eliminates the need for expensive microcontrollers with large
memories that are required in existing digital bus architectures, claims ADI.
Supporting up to 32 discrete
upstream and downstream audio channels, the low-cost audio transceiver provides
50 Mbps of data bandwidth. All standard audio sampling rates are supported as
is daisy-chaining of multiple AD2410 slave devices to a single master. Unlike
existing digital bus architectures, system delay is fully deterministic at all
slave nodes, making the AD2410 suitable for applications including active noise
cancellation, in-car communications, and microphone beam forming.
