Hi all,

 

I checked following thread.

Q: What happens to the PLL when the REFIN is removed ?. 

 

 

The ADF4159 is only DLD function, can not use ALD function.
When the REFIN is removed on the ADF4159,
there is the case that the lock detection is not the correct output.
Some time is to "HI", some time is to "Lo", at the output of MUXOUT DLD.
This test method is , the SG on / off, or disconnect the cable for REFIN.

Please advice something for us to do this.
The best way to take the correct detection is only the continuous REFIN ?

 

Best regards,
sss
