Hello E2E,
We’re wondering if we should be powering the DP83867IS with the 3-supply configuration to reduce a little power. I’m wondering, how important is the sequencing of the 2.5V and 1.8V rails for this? I’m fairly confident that I will be able to meet the 25ms with the ramp-up, but I don’t really know about the powering down of the 1.8V before the 2.5V. Can you find out how critical this is?
Thanks!
Russell
