LMK03001C / Analog Lock Detect , Digital Lock Detect

Other Parts Discussed in Thread: LMK03001

Hello,
 
LMK03001C has the LD pin and we can use this pin by Analog Lock Detect and Digital Lock Detect.
I can see the description of Digital Lock Detect by datasheet page 18.
But I can't find any information of Analog Lock Detect.
 
1) Could you please kindly let me know difference between Analog Lock Detect and Digital Lock Detect ?
 
2) I think that Analog Lock Detect need external circuit.
    Could you please kindly let me know how to design ?
    If there is any Application note about Analog Lock Detect, please let me know.
 
Best Regards,
Ryuji Asaka

    Hello,
     
    Sorry for bothering you.
    I found thedescription of the  Analog Lock Detect in the Dean's BOOK 4.
    Thus, I update question as below.
     
    (1)Does this description apply to LMK03001C ?
     
    (2)Digital Lock Detect
    Please see the attached file.
    There are my image of DLD Active High output waveform.
    If LMK03001 detect Digital Lock , Is LD output fixed by once( ② waveform in the attached file) operation any time ?
    Or are there any possibility of ① waveform ?
     
     
    Best Regards,
