AD2410W: Automotive Audio Bus A2B Transceiver Preliminary Data Sheet - 1

Automotive Audio Bus A2B Transceiver AD2410W Preliminary Technical Data A2B BUS FEATURES GENERAL DESCRIPTION Line topology Single master, multiple slave Up to 10 meters between nodes Up to 40 meters overall cable length Communication over distance Synchronous data Multichannel I2S/TDM to I2S/TDM Clock synchronous, phase aligned in all nodes Control and status Information I2C to I2C Phantom power Configurable with SigmaStudioTM graphical software tool The Automotive Audio Bus (A2BTM) provides a multi-channel, I2S/TDM link over distances of up to 10 meters between nodes. It embeds bi-directional 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 transceiver chip at the host controller is the master. It generates clock, synchronization and framing for all slave nodes. The master A2B chip is programmable over a control bus (I2C) for configuration and read back. An extension of this control bus is embedded in the A2B data stream allowing direct access of registers and status information on slave transceivers as well as I2C-to-I2C communication over distance. ADDITIONAL AD2410 TRANSCEIVER FEATURES Configurable as A2B bus master or slave I2C Interface 8-bit to 32-bit multichannel I2S/TDM interface Up to 32 upstream channels or combination with up to 32 downstream channels I2S/TDM or PDM Microphone inputs Complete technical specifications are available for the A2B transceiver.
