AD2427WCCSZ01

AD2427W is an automotive audio bus A²B transceiver. It provides a multichannel, I²S/TDM link over distances of up to 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, daisy chained nodes at different locations to contribute and/or consume time division multiplexed (TDM) channel content. Application includes audio communication link, microphone arrays, beamforming, hands free and in car communication, active and road noise cancellation, audio/video conferencing systems.

• Communication over distance, synchronous data
• Synchronous clock, phase aligned in all nodes
• Control and status information I²C to I²C, GPIO and interrupt
• Bus power or local power nodes
• Configurable with SigmaStudio graphical software tool
• AEC-Q100 qualified for automotive applications
• Digital core logic supply voltage range from 1.70 to 1.98V
• Typical transceiver supply voltage is 3.3V (Applies to the ATRXVDD and BTRXVDD pins)
• 32 lead LFCSP-SS package
• Temperature range from -40°C to +125°C
