I just realized the LFRX does not have the clock pin. The BasicRX does, and should also work the same way for your application. So if you need the clock output, the BasicRX is a better choice.

And, as a follow-up, you might need to muck with the appropriate UHD driver to get it to enable those clock pins,and drive them at a suitable rate.

You will likely have to "crib" from the drivers for cards that require a refclock--like, well, all of them *except* for BASIC_* and LF_*.

In fact, it might be reasonable to suggest that there be an option in the standard drivers to enable those pins at a default rate of 10Mhz or something
  for the BASIC_* cards.  Or some easily-usable API frob to do so.
