I used the eval board software to set synthesizer paramters as follows.

The synthesizer did not achieve phase lock after pressing Update All.

 

I discovered the synthesizer would lock to the desired frequency if the 8-bit band select clock divider was set to any value other than 2 (decimal) including 0.

 

Has anyone else experienced this characteristic or have an explaination ?
