AD9361 REF_CLK_Reference

I have a query on REF_CLK of AD9361. i am planning to use 40 MHz as reference of AD9361 with +/- 2 PPM and will it effect LO step size. My LO step size requirement is 5 Hz. I found TCXO which we used in AD9361 Evaluation board. It is TSX-3225 40.0000MHZ (EPSON) make, if i use same TCXO in my application, will i get LO step size as 2.4 Hz?


is that AD9361 Eval board (AD-FMCOMMS2-EBZ) will work for 2.4 Hz LO resolution?


For getting 5 Hz LO step size what type of TCXO and how much stability required, Input level?


Kindly suggest TCXO considerations of better performance like LO step size and Jitter.
