AD2428WCCSZ-RL

AD2428 is an automotive audio bus A²B transceiver. It provides a multichannel, I²S/TDM link over distances of upto 15m between nodes. It embeds bidirectional synchronous pulse-code modulation (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, daisychained nodes at different locations to contribute and/or consume time division multiplexed (TDM) channel content. It is widely used in application such as audio communication link, microphone arrays, beamforming, hands free and in car communication, active and road noise cancellation, audio/video conferencing systems etc.
