A2B Module 2nd generation EVM
A2B EVM provides stereo audio I/O for A2B.
AD2437 based A2B Module
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 […]
Linear 4 channel microphone array A2B Module
The AB0204 module has four microphones arranged in a linear array for developers of audio beamforming applications. It is phantom powered over the A2B bus so does not need any external supply. Unlike the I/O expansion boards that plug in to the Clockworks A2B OEM module the AB0204 is a complete A2B board. What is […]
AudioXpress A2B article series
Clockworks authored an introductory A2B article series in AudioXpress magazine. This magazine is a great resource for both professional and other audio designers. To check out the 4 part article series on their website click the image below.
32 second explanation of Clockworks’ A2B hardware
Clockworks’ A2B and related products are designed for developers looking for fast evaluation, prototyping, and small volume deployment of A2B based systems. We made a little video to help out people with short attention spans…unfortunately it came out 2 seconds longer than the proverbial 30 second video.
A2B control from Python via SigmaStudio (AppNote003)
ADI’s SigmaStudio tool for A2B topology set up can be controlled via a Windows COM API provided by Analog Devices. In this example we’ll create a small Python program to load an A2B configuration and then capture data from a temperature sensor connected to one of the nodes. This example is specifically focused on the […]
USB audio to A2B interface with miniDSP’s MCHStreamer (AppNote002)
During prototyping and development it can be convenient to be able to send or receive audio from a host PC (Windows or Mac in this case) for injecting signals or for monitoring -particularly if using SigmaStudio for A2B topology modifying routing to accommodate testing is trivial. miniDSP offers an easy to use board based on […]
Automotive Audio Bus (A2B) development and hardware products
Analog Devices’ A2B system provides a way to send bidirectional control and digital audio data over low cost twisted pair wire in a simple daisy chain configuration of up to 11 nodes. Initially developed for use in automotive applications to reduce weight and cost compared to big cable harnesses, Analog Devices has recently made the […]
Six new A2B hardware options for developers
Clockworks has expanded its offering of modular A2B options with a new A2B to I2S/I2C/GPIO breakout module that allows customers to use their own preferred A2B connectors instead of the DuraClik connectors normally used on development boards. At the same time we’ve also introduced five plug-on modules to simplify hardware development – these plug-ons do […]
SYNC or not? AD2428 Master node initialization.
According to ADI’s AD2420(W)/6(W)/7(W)/8(W)/9(W) Automotive Audio Bus A2B Transceiver Technical Reference manual (ver 1.1) after power is applied and the chip comes out of power on reset (page 3-5): The A2B host then sets the A2B_CONTROL.MSTR bit in the transceiver before driving the SYNC pin (the input clock to a master-enabled transceiver’s PLL) at the […]
