Re: [Discuss-gnuradio] LFRX as IF stage questions

[Nemanja Savic]

I can't use basix_rx, cause i can't get it. the problem is i want to use ti's cc1000 as rf frontend. it has if output at 10.7 MHz.

The problem is i can't make pll of cc1000 to lock, and I assume that the problem is mayne in not accurate quartz reference

due to bad loading capacitors.

Yes I agree it would be great to be able to enable some clock for lf boards.

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.
