Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD2437KCPZY A2B® transceiver provides a multi-channel, I2S/TDM link with distances between nodes of up to 30 metres. It embeds bi-directional synchronous pulse code modulation (PCM) data (e.g., digital audio), clocks, and synchronisation signals into a single pair of differential cables.The A2B supports direct point-to-point connectivity, allowing multiple daisy-chained nodes at different locations to provide and/or consume time-division multiplexed channel content.

The A2B is a single-master, multiple-subordinate node system in which the transceiver on the master controller is the master node. The master node generates clocks, synchronisation and framing for all subordinate nodes. The master A2B transceiver is programmable via the control port (I2C/SPI) for configuration and readback.An extension to the control port protocol is embedded in the A2B data stream. This allows direct access to registers and status information on subordinate transceivers, as well as I2C-to-I2C, SPI-to-I2C, or SPI-to-SPI communications from the host to subordinate node peripherals. SPI-to-SPI communications between subordinate nodes can be performed directly without the involvement of the master node.
