I'm not an experienced hardware guy, but it looks like it would work in the usrp. Please tell me if I'm wrong.

I believe the USRP needs a 3 Vpp clock in, and this TCXO only outputs 0.8 Vpp. Plus, it's a clipped sine. So you may want to throw it through a squarer that will bump it up to 0 -> 3V before putting it into J2001. Is this right Matt?
