AD2428WCCSZ02-RL

AD2428WCCSZ02-RL is an automotive audio bus A2B transceiver. The Automotive Audio Bus (A2B®) provides a multichannel, I2S/TDM link over distances of up to 15m between nodes. It embeds bidirectional synchronous PCM data (for example, digital audio), clock, and synchronization signals onto a single differential wire pair. A2B supports a direct point to point connection and allows multiple, daisy chained nodes at different locations to contribute and/or consume time division multiplexed channel content. The transceiver can connect directly to general-purpose DSPs, FPGAs, ASICs, microphones, ADCs, DACs, and codecs through a multichannel I2S/TDM interface. It also provides a PDM interface for direct connection of up to four PDM digital microphones. Typical applications include automotive audio communication link, active noise cancellation and microphone arrays for hands free and in car communication.
