I tried to order an xilinx FPGA dev board and thought of implementing DANTE on that but it seams DANTE is more corporate development and big budget. Fair enough.

So now i'm adding an xcore-200 for AVB 1 gigabit ethernet audio IO.

I found the IC quite difficult to route and i'm not entirely convinsed I can get more than 8 channel in and 8 out over single TDM data lines. I only have 1 in and 1 out left on the ADAU1467 DSP. 

but , 8 in 8 out and possible 16 in 16 out on ethernet is OK !!!!

I might be able to throw in some AES3 IO to from the same chip if I get good at using there IDE.

I'm hoping to be able to power off the XCORE-200 if no ethernet or AES3 is in use to for power saving. I think it will probebly use 1amp at 3.3v when all the channels are up !
