Hi Team, hoping for your assistance.
When designing an Ethernet Interface using DP83869HM PHY . We have a question regarding Voltage Sequencing of VDDA2P5(2.5V), VDDA1P1(1.1V), and VDDIO.
As per the datasheet Figure-115, 1.1V and 2.5V both the rails are coming together (1.1V & 2.5V -> VDDIO ).
Can I have any of the below voltage sequencing:
1. 1.1V -> 2.5V -> VDDIO
2. 2.5V -> 1.1V -> VDDIO
3. VDDIO -> 1.1V or 2.5V
From the datasheet, I understood, VDDIO should come up after 1.1V and 2.5V(1.1V & 2.5V -> VDDIO ). Please let me know any sequence is required to be followed for 1.1V and 2.5V.
Thank you very much.
