AD2426KCPZ General Description

The Automotive Audio Bus (A²B^®) provides a multichannel, I²S/TDM link over distances of up to 15 m between nodes. Itembeds 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.

Key Features

Line topology
- Single main node, multiple subordinate nodes
- Up to 15 m between nodes and up to 40 m overall cable length
Communication over distance
- Synchronous data
  - Multichannel I²S/TDM to I²S/TDM
  - Synchronous clock, phase aligned in all nodes
  - Low latency node to node communication
- Control and status information I²C to I²C
- GPIO and interrupt
Bus power or local power subordinate nodes
Configurable with SigmaStudio/SigmaStudio+ graphical software tool
AEC-Q100 qualified for automotive applications

Application

Audio communication link
Microphone arrays
- Beamforming
- Hands free and in car communication
