I doubt you can do this.  It would look like a 64MHz square wave.  You 
could feed in a reference wave (perhaps from a signal generator or other 
accurate clock) and look at it's deviations from the reference freq to 
deduce what the 64MHz clock is doing.

Maybe if you had 2 USRPs you could feed the clock of one into the RX of 
the second.
