Things the Xylo has going for it:
Cost -- Xylo w' all connectors is $150, USRP $550. Xylo comes a
lot closer to 'no thought, knee jerk' buying than USRP
Windows oriented (this will not be a plus for all)
Ethernet support (sure one could do Ethernet on the USRP with the
appropriate FPGA code and some hardware to connect it)
Things the USRP has going for it
Open source everything (FPGA code, Schematics, applications)
Linux oriented (this will not be a plus for all)
On board hi speed A/D and D/A converters
The current thing folks are looking at with the Xylo is to interface a hi
quality 192khz, 24 bit Wolfson A/D converter to a computer for an SDR 1000,
SoftRock or other narrowband SDR style hardware. Some thoughts to trying
to do some of the quad signal generation and perhaps the QSD in the FPGA,
but I don't know how much serious work has been done on that as yet.
Ultimately, if folks are successful at using the Xylo to interface a
Wolfson then maybe a custom FPGA + Wolfson + FX2 + whatever board gets done
to bring the cost down -- I think the Xylo's just being used for initial
development and experimentation.
