Tool/software:
We are trying to build an IOT Gateway. In our design, we are using DP83869HM to evaluate both SFP (Fibre) and RJ45 (Copper), connected one at a time in our design.
I wanted to understand how to power this PHY and what all power rails need supply? From the datasheet, I can see that there are 4 four power supplies we need to provide to the PHY i.e. VDD1P1, VDDA2P5, VDDA1P8, VDDIO and apparently in some defined order.
1. Do I need to power all 4 supplies with 1.1V, 2.5V, 1.8V and 3.3V/1.8V/2.5V respectively if I need to evaluate both Fibre and Copper (one at a time though).
2. Would I require a PMIC for supplying power to these sections or just buck converters will do ?
