Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD2427KCPZ Automotive Audio Bus (A2B®) provides a multi-channel, I2S/TDM link between two nodes up to 15 m apart. A2B is a single-master, multi-slave system, with the transceiver in the master controller used as the host. The host generates clock, synchronization, and framing signals for all slave nodes. The host A2B transceiver can be programmed through the control port (I2C) to realize configuration and read back. An extended version of the control port is built into the A2B data stream, which can directly access the register and status information of the receiver and sender from the machine, and realize cross-distance communication from I2C to I2C.

A2B bus features:

Linear topology

Single host, multiple slave

The maximum distance between nodes is 15 m, and the overall cable length is 40m

Long-distance communication

Synchronous data

Multi-channel I2S/TDM to I2S/TDM
