New ContributorAgilex 7 Power Sequencing WITHIN a Power Group
Hello Intel community!
I am designing the power solution for an Agilex 7 F-series device and am hoping I can find a little more information pertaining to how exactly the voltage rails turn on.
I have read the support documentation and understand the voltage rails are separated into 3 groups with Group 1 voltage rails needing to be at 90% of their nominal voltage level before you can start turning on Group 2 voltage rails and so forth.
Since there are multiple voltage rails within a single group, is there any timing information or sequencing of voltage rails within a single group? More specifically, I am wondering if there are delays between group 2 voltages: VCCCLK_GXF, VCCH_FGT_GXFR, VCCPLL_HPS, etc.
I have one regulator that is powering multiple group 2 voltage rails. If all of them start drawing current at the same time, the resulting voltage droop will put us below the acceptable voltage minimum. I haven't found anything in the documentation on if these rails within a group will turn-on simultaneously and how they start drawing current once they are up.
Any information or personal experience with the Agilex 7 voltage sequencing would be helpful!
