WhiteBull:

Glad you address the problem, congratulations!

I didn't realize the problem was caused by the 1.2V power supply. Thanks wktk_smile for your experience.

Hi Ian,

I'd like to try the isolator board BUT I need spdif out, also using the si570, like its sound. Can I remove the ribbon cable (dont use the fifo input) and power the board seperately like in the attached pic? Thanks!

umm, where is the source coming from? you have disconnected both the inputs for audio, or you will use i2s input from USB or something?

I know its Ians picture, but you made no comment, nor indication of where the signal might come from in your notes. so yes if you power the board separately, you can use it like that.

Hi edbk,

If you don't need input I2S from spdif board, yes, you don't need the black I2S input cable.

However you have to use the white FFC/FPC cable for running the spdif board.

You don't need the 5V DC input on the spdif board if it works with FIFO.

Ian

ah whoops, I knew there was something eating at me, so you still need the J7 FPC for spdif output only? what for? control signals and output selection or something? its not mentioned in the datasheet other than being for future revisions and I also guessed the spdif input selection/control was sent over it. or is i2s sent over it for output too?
