> (http://www.plxtech.com/products/io_accelerators/PCI9030/default.htm) That's one route, though 32-bit 33-MHz PCI is pretty much the bottom of the barrel these days. Hence the interest in PCI-Express and/or Express Card. > You might be able to do gigabit ethernet if you just pushed out the data > to and from the USRP in plain old ethernet frames directly to a gigabit > ethernet port on the PC. No IP headers and no switches in between. Yes, there's no particular problem doing Gig E. You can run it 100m with CAT5e and 10+ km over fiber. Both of these are good for putting the USRP on the tower, next to the LNA and PA. http://en.wikipedia.org/wiki/Gigabit_Ethernet > I know someone who used gigabit ethernet driver chips hooked to an FPGA > in order to push lots of digitised SVGA video data down a long length > of CAT5e for a KVM application.
