LMK04828B PLL1 & PLL2 is not locking

Hi,


I am using LMK04828B PLL. The PLL1 & PLL2 of the LMK04828B is not locking. Before configuring the lock detect status is 1 & after configuring the lock detect status is also 1. I have used PLL lock detect pin as output inverted (push pull type) & the below register value for loading.

What will be the possible cause of the lock detect error ?
