Our unit will use PCI for that purpose to get better latency and throughput. USB is not designed for real-time data. > Some people on > the list are working on clocking a USRP through a phone so that much less > oversampling and much lower data rates become possible.

Could you elaborate a bit, please? > Thanks for sharing your ideas. Looking forward to your SDR module. Well, we expect first prototypes be available not earlier then at the middle of the year and final version not earlier then at the end of the year. So don't count on us in short term. -- Regards, Alexander Chemeris. _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
