There is a mictor connector (J301 on both USRP2 and N2x0) that has 32 signal and 2 clock pins all free to be used in the FPGA. Searching for "mictor" in the archive of this forum will find other posts about this.

However I do want to drive home the point that you are unlikely to find an ARM processor currently that is capable of doing anything useful directly with RF data at bandwidths greater than which the E100 is capable or indeed one with a flexible physical interface that can support 60MB/s....you're clearly in the realm of high-end DSP processors at those rates.

Well, keep in mind that if the goal is really 60MB/s, rather than 60Msps, that's only about a factor of 5 beyond what an ARM can resonably
  do for lightweight processing.
