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 […]
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 […]
Jitter spectrum measurement with a DSO (AppNote001)
In testing some of the A2B hardware what appeared to be high jitter on the clocks was observed. While specialized scopes & software are available for making jitter measurements one was not available at the time measurements were needed. The basic idea is simple enough – measure the clock edges and see if they are […]
LTspice files for A2B simulation
TechNote TN007 describes LTspice simulations used to illustrate the functioning of the ADI suggested analog network design for their AD242x series parts used for A2B interfacing. The LTspice files are available in a .zip that can be downloaded. These files do not include the detailed TDK common mode choke part model, which is available from […]

Quick bus powered A2B slave node hack
A quick system was needed where the Clockworks module based A2B node (operating as a slave) could be bus powered to avoid the need for a separate set of power wires. The final goal was to attach some GPIO signals to the module’s AD2428W GPIO lines. While no magic smoke was released, it didn’t work […]
