Copper GigE is sufficiently cheap and ubiquitous that a DAC/ADC board should use it. But for the people who want to mount the whole thing on a tower and run a nonconducting fiber back to their processing shack, a converter from copper GigE to fiber GigE is small, low power, and only costs a few hundred dollars. > Though GigE sounds like a good idea to pursue, has anyone thought about > using 2 or more USB 2 interfaces as an alternative? A good hack! I don't know if common multi-USB2 host interfaces can run all the ports at top speed simultaneously. Some look to software like a single interface connected to a hub. I wonder if we could make a "Second USB2" daughtercard that would use some of the FPGA's digital I/O pins to drive another USB2 chip? (The protocol over the USB would need to change to add packet numbers, or to otherwise provide for a way to synchronize the two streams; but this is probably a simpler change than making a GigE interface.)
