In fact, I already tried to make such a circuit using

some time ago, but it wasn't as straight-forwardd as I hoped and it was
never completed :(
A while back there was a posting[1] on the OpenBTS ML that mentioned
positive results using this exact PLL as clock input for a USRP. The
posting itself does not contain the part#, but I remember to have read
it in a follow up post or so. This setup did not use a phone as input to
the PLL, but nevertheless used such a PLL to feed the USRP.
Could you please elaborate on which problems you were facing?
Kind regards,
