Can I get one?
I am a student living in Florida testing with OpenBTS, but I still haven't found a suitable clock for my USRP.

Normal delivery for a custom product like this is 7-12 weeks and I ordered these parts last Nov. I will be testing it on our USRPs as soon as they come in. I have the option of adding a potentiometer to adjust the freq +/- 5ppm.
