I am working on some optics-based project, for which I need to use 2 audio codecs at both TX and Rx and, just to make timing synchronization between TX and Rx. I am planning to use the AD1938 evaluation Board to convert audio/voice signals into digital form. I am only interested in discrete 1 and 0 outputs of ADCs so that I can further use this bit frame for the next block operation. I am unable to get the idea about, how to accomplish my aim with this evaluation board. I want to take this data serially out.
If anyone is having any idea about the AD1938 Evaluation board, then do help me. Any hint is also welcome.
Thanks & Regards
The user guide does cover how to use this board for many different serial communication standards. It is available on the eval board web page: https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-AD1938.html#eb-overview
There are two optical connectors on the PCB but these are only used for the SPDIF serial input and output. Since you mentioned Optical I thought I would mention this in case you are planning on using the optical connectors only for TDM or I2S signals. You cannot use the optical connectors for this. If you have capabilities to send and receive SPDIF then this eval board will do this for two channels in and out.
If you are going into a computer with the digital audio then you may be able to use the SPDIF. It is a simple way to use the board.
