How can I find/determine the current requirements for:

SVDD_1.05V SerDes Core Supply

XVDD_1.05V SerDes Pad Supply

for a P2020 using all 4 lanes of PCIe (x1, x1, x2)?

Thanks,

Todd

For your configuration PCIe (x1, x1, x2) estimated power numbers are 0.38W (SVDD) + 0.13W (XVDD) = 0.51W


Have a great day,
Andrei
