ProtoDAC TDA1387 X8 project

[hifinet]

Hi all,

After a long search, I acquired an Allo Kali and am really happy with the result.
My next project is integrating ProtoDAC with a USB to I2S board so that I can use it at my workplace. Please let me know if anyone has tried that.

I haven't done USB directly to I2S (USB to SPDIF, SPDIF to I2S in my case), but it should be very straightforward. You can get high quality boards like the I2SoverUSB, with built-in galvanic isolation and low phase noise clock crystals. There are also cheaper Ali boards using various chipsets: CM6631A , STM32 , TE7022 , PCM2706 . Amanero is a search term to use. The better boards get to the price of the I2SoverUSB board. Max bit depth and sample rate varies. USB isolators are available: ADUM3160 or Topping .
