ADRV9371 can't sync with reference clock

Hi :

 I was using a generator to supply 30.72MHz to Ref Clk on the ADRV9371. For trying to track down a Tx transmit issue, I decided to configure 122.88MHz for Ref Clk.  

 

In RadioVerse, if I go to program the ZC706 with a setting of 122.88MHz and have 122.88MHz signal connected, but when I press "program"  I will get a pop up warning "AD9528 Clock not Syncronized. Please check the setup and refer to quickstart guide for extra information". I ignore this message, I still can transmit Tx "tone" signal but PLL state 1 always on and state 2 just blinking, Is it work will or not, How can I fixed it?
