Reg power-to-ground impedance Vccp - Agilex 5

[amolkumar]

Hi All,

we are considering A5ED065BB32AE5SR0. We found that the Vccp (0.78V) power-to-ground impedance, when powered off is only 2~4 ohms. Is this normal?

This is a duplicate of the case that I have supported.

However, I will put the findings here:

From what I got, if 0.78V is for the VCC core, and VCCP is tied together with VCC, then it is normal. Please be informed that the impedance value is highly dependent on the board design, and it varies on different boards as well. It’s possible to have a low impedance value path based on the internal circuitry of the custom-made board.
