The AD2410 transceiver from Analog Devices, Inc. (ADI)is the first in a family of devices that enables ADI"snew automotive audio bus (A B), which significantly reducesthe weight of existing cable harnesses, resulting in improved vehicle fuelefficiency while delivering high fidelity audio. In addition, the AD2410transceiver also eliminates the need for expensive microcontrollers with largememories that are required in existing digital bus architectures, claims ADI.Supporting up to 32 discreteupstream and downstream audio channels, the low-cost audio transceiver provides50 Mbps of data bandwidth. All standard audio sampling rates are supported asis daisy-chaining of multiple AD2410 slave devices to a single master. Unlikeexisting digital bus architectures, system delay is fully deterministic at allslave nodes, making the AD2410 suitable for applications including active noisecancellation, in-car communications, and microphone beam forming.
