ADZS-AD2428MINI

Product Details

ADZS-AD2428MINI is a low-cost, mini break-out board which can interface with EV-SOMCRR-EZKIT (via a 100-pin connector) or any custom board (via a 32 pin 0.1" header). It supports main and subordinate node capability as well as bus and local power configurations.

An Automotive Audio Bus (A²B^®) system consists of a single main node and at least one subordinate node, where the transceiver at the host controller is the main node. The main transceiver generates clock, synchronization, and framing for all subordinate nodes and is programmable over a control bus (I²C) for configuration and readback. An extension of this control bus is embedded in the A²B data stream, which enables the host to directly access subordinate transceiver registers and any I²C-connected peripherals on subordinate nodes.

Transceivers can connect directly to PDM microphones and to numerous peripherals via I²C and a multichannel I²S/TDM interface. Finally, the transceiver also supports an A²B bus powering feature, where the main node supplies voltage and current to the subordinate nodes over the same daisy-chained, twisted pair wire cable as used for the communication link, thus eliminating the need for a power supply on bus-powered subordinate nodes. Due to the numerous configurations that are possible for a given A²B system, there are several evaluation platforms that can be used in combination to verify system operation, as summarized in the table below.
