Is it possible to power down all the PLLs and VCO of a MAX 10 Device?

We are designing a board in which we would like not to use the analog features, like PLL, VCO and ADCs of a MAX10. UG-M10CLKPLL par. 2.3.6 states : "The only time that the VCO is completely disabled is when

you do not have a PLL instantiated in your design". Does it mean that whitout instantiations of a PLL in the design we can assume that all the VCO are powered down? Do we also need to connect to GND the AVDD?

Thank you

Hi @MRigh​ 

PLL unused pins can be connected to GND. Ref page no:4

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/pcg-01018.pdf

And please note, if you are not using the analog feature in Max 10, still needed power to these blocks by VCCA. and VCCD_PLL Page no:15

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/pcg-01018.pdf

But, if you using the PLL IP, the whole PLL IP block will not be used.

But cannot say the power to VCO is completely cutoff.
