AD2427WCCSZ-RL AUDIO A2B TRANSCEIVR 1CH 32LFCSP

AD2427WCCSZ-RL

GENERAL DESCRIPTION

The Automotive Audio Bus (A2 B®) provides a multichannel, I 2 S/TDM link over distances of up to 15 m 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. A2 B 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. A2 B is a single-master, multiple-slave system where the transceiver at the host controller is the master. The master generates clock, synchronization, and framing for all slave nodes. The master A2 B transceiver is programmable over a control port (I2 C) for configuration and read back.

An extension of the control port protocol is embedded in the A2 B data stream, which grants direct access of registers and status information on slave transceivers as well as I2 C to I2 C communication over distance.The transceiver can connect directly to general-purpose digital signal processors (DSPs), field-programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), microphones, analog-to-digital converters (ADCs), digital-toanalog converters (DACs), and codecs through a multichannel I 2 S/TDM interface. It also provides a pulse density modulation (PDM) interface for direct connection of up to four PDM digital microphones. Finally, the transceiver also supports an A2 B bus powering feature, where the master node supplies voltage and current to the slave nodes over the same daisy-chained, twisted pair wire cable as used for the communication link.
