Output signal phase ADF4351

Good day!

 

I've got a question about ADF4351 synthesizer.

Looked through its datasheet, but didn't understand one thing: would its output clock signal's phase be the same (may be with some CONSTANT offset), as the input reference signal's phase?

I mean if, for example, I have two boards with ADF4351. I have one common 25 MHz input clock on these boards and I program both of the ADF4351 for the output of 2.5 GHz. Would there be random phase difference between output clocks of these two boards on power up?

 

And if there would be random phase difference, can I use Resync feature to make this phase delta constant?

 

Thank you!
