ADF4351 can't get it work on low freq

Hi, I have finally got the samples for ADF4351, and I'm trying to make it work, but so far with no success.

I need to cover 60MHz to 1100MHz.

Can you please guide me with some information according to the registers setup.

I can successively dial any frequency around 1000MHz but when it comes below 200MHz I don't get any LD.

Can some one give me an example (what should I program into the registers) of dialing the following frequencies:

60.025MHz
120.025MHz

240.025MHz

I will use fractional option because I need a resolution of 25KHz.

My reference is 10MHz.


Thank you.
