PLL output frequency accuracy issue

Question

Sir, 
 
 I have tuned the PLL for 1150 MHz but at the output i am getting the 1152 MHz. Lock detect signal is coming means PLL is locking.I have set PFD frequency as 1 MHz. Reference clock for PLL is 10MHz. 
 Please help me to solve the accuracy issue.I have requirement of +-50KHz accuracy requirement.

Regards 
 Chandan

Hi Chandan,

have you synchronized your spectrum/signal analyzer with the reference source? 2MHz is too much for this but still, I suggest firstly that. Are you using the EVAL board? you can also add your register settings here or if you are using EVAL's control software, screenshot of the GUI.
