I order the HMC835 Eval  board and test it, fractional mode is working well, but exact frequency mode is not working at Eval board. what I need pay attention to setup exact frequency mode.

When I click exact frequency mode, PC program go into the mode, I can see to Reg Ch value, but lock LED shown me that PLL is not lock, and real PLL output frequency is not changed.

Who can tell me how to setup exact frequency mode? this function is nice.
