QThere is a LD pin (pin 25) in ADF4350. What is the difference between this pin
and the MUXOUT used as digital lock detect function?
ALD is dedicate for Digital Lock Detect output, it is not related to register
word, just a direct output of DLD signal;
MUXOUT is more like a pin for debug or test purpose, it can output digital lock
detect signal also, but need register program. it can also output ALD, VDD, R
div, N div, etc. also need register programming.
