ADF4159 AVdd pin functionality

Question asked by werty on May 19, 2016

Do the AVdd pins internally connect together or do they connect to different parts of the IC?

I would like to power down un-used parts of the IC in some instances, for example route the fractional-n output to MUXOUT and power down the reference and charge pump circuits, i.e. utilise the PLL simply as a fractional divider.


Please can you describe what the AVdd pins connect to and if there is a possibility of implementing my idea.

Many thanks.
