Qualified for automotive applications The Automotive Audio Bus (A2B®) provides a multichannel,
I2S/TDM link over distances of up to 15 m between nodes. It
embeds bidirectional synchronous 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 or consume time division multiplexed channel
content. A2B is a single-master, multiple-slave system where the …
