ADF4360-7 power down mode

Hi All,

Today, one customer asked me about behavior of ADF4360-7 power down mode.

Then, I have following questions about it.

When get CE to low and power down the device,

  1. what should be expected as the state of MUXOUT(digital lock detect mode) pin?
  2. they reported that MUXOUT will be low for just a moment and then high afterward.
    Is it correct behavior of the device? If it is not, what should they do for solving this behavior?

I'm looking forward to your help.

Best regards,
