If you have access to gerbers and IPC-356 netlist there is great, free tool for viewing boards - ZofzPCB: FREE 3D Gerber Viewer + Premium STEP Export

Thank you. When opening the gbr files for the ESS reference project, I am getting the following syntax error. "complex apertures tracks not implemented" for the topsilk.gbr file. I am unsure what that means and how to fix it.
The Geber file folder also comes with a set of PDFs for each layer. Not the ideal way to visualize the tracks, but currently I am using it to see how the signals flow.

Hi Mark,ESS has some advice on dac board design in the following document: http://www.esstech.com/index.php/download_file/view/69/267/
Also, one can download the ES9038PRO evaluation board design files, so one can study how they laid out the reference dac board.

the ess files are not accessible with that link, would you be having a copy that you could share.
Replying to you PMPM sent.
I am using ESS9023

Oh, well aside from basic good practices, almost nothing from 9038pro is applicable to 9023Replying to you PM

well what to do than I need to make use of the linkplay a28 module.
How do you select the oscillator
is it suppose to be 49.158MHz or 50.000MHz
Its 45.1584 MHz or 49.1520 MHz. Look them up in the table at: https://en.wikipedia.org/wiki/Crystal_oscillator_frequencies
Also see the table on page 4 of ES9023 dataheet. For async mode, probably what you want to use, either of the above frequencies should work for 24/192kHz audio (although 'best performance' will only apply up to 24/96).

yes, i am having difficulty understanding that table, This would be my first DAC-based project.Its 45.1584 MHz or 49.1520 MHz. Look them up in the table at: https://en.wikipedia.org/wiki/Crystal_oscillator_frequencies

and
if I were to use a PCM5102A could someone explain me that please- its table.
I2S signal names are explained at: https://en.wikipedia.org/wiki/I²S
Fs is the frame sample rate. For PCM its the LRCK frequency (e.g. 44.1kHz, 192kHz, etc.).
