not sure if there is anyone here on this who isnt aware of this or not, but you also need Ians i2s fifo module, this by itself will be useless I would think

I thought that too, but I'm not so sure now that I've re-visited the block diagrams.


There is no comms connection to the FIFO, just takes i2s from the clock board, as far as I can tell.

Obviously, the FIFO would be a pretty handy tool if you're interested in getting the last drop of musical juice from your favourite DAC chip, so consider yourselves encouraged to look into that folks!

edit: OK as hochopeper says you dont need it but its strongly recommended if you want to isolate from the computer and provide a seamless terminated low jitter connection for mclk on this NOS driver board. I figured there would be some communication between the 2 boards, but it appears not.

seems a nobrainer to me to get both, but its not strictly required

Yes, you are right. This daughter board was designed as a universal I2S to PCM converter. It just needs I2S and MCLK as input, and can receive I2S signals from most popular DIR and USB audio adapter. FIFO is not a must for it, but would be highly recommended, as well as the isolator.
