Let me give you a bit more information here.
According to the N210 schematics, the clock's PLL has a BW of 3kHz.
This means that noise beyond 3kHz is dominated by the VCXO on board.
Noise blow 3kHz is dominated by the reference clock. This means, that
if you can keep the noise of the reference clock low at frequencies lower
than 3kHz, then you will have good performance.
Depending on what you use as refernce clock, you have to identify the
noise sources and their properties and then work on those that have
most impact on your performance.
