He's using a USRP2 with the UHD patch. Since the USRP2 is always 100MHz sampling, I guess it uses a modified version of the 64MHz TRX (because it needs resampling). But the USRP2 can have it's 100MHz local clock locked on an external reference to get it at _really_ 100MHz and achieve good clock. Cheers, Sylvain |
