ADF4106 Lock not not-Lock Detect

To Whom it May Concern,


The Lock Detect Output of the ADF4106 seems to be High when the device is Locked. But when unlocked, the Lock Detect Output toggles High and Low. Is this the correct operation of the Lock Detect Output? Digital Lock Detect Output from the MUX is selected. Although, even the analog output Lock Detect works about the same.


Is there a way to program the ADF4106 to have a solid Low Output when un-Locked?


If not, is there a simple circuit, R's C's diodes, that can be used to create a logic Low when unlocked?


Else I suppose an edge detector circuit is what is recommended.


Thank you.
