Clockworks’ A2B AB0331 module offers developers a simple way to develop A2B products by creating prototypes based on the A2B module connected to EVM board(s) for the desired peripheral functions. Typically Clockworks’ A2B module is used with ADC or DAC boards, but can also be used with things like class D amplifier devices with direct I2S input or digital microphones with I2S output.
The module uses the latest generation ADI transceiver, the AD2437. The AD2437 supports a number of enhancements over the AD2428 device: Longer distance between nodes (30m between nodes, 300m total length, and up to 16 nodes). the AD2437 also supports what ADI refers to as CFG4 power, which support up to 24V at up to 2 amps total.
The module can operate as a root (controller) or client (peripheral) node device. It requires external power, i.e. it is not a phantom powered node. It can provide bus power to the carrier which in turn can repower the board.
While I2S is mostly used for audio data, the actual data carried can be anything that fits the bit depth (16, 24, or 32) and rates (44.1, 48, 96 kHz) that A2B supports.
The Clockworks A2B module is available with an EVM kit.
