Hi,
I am using Ethernet PHY(DP83869HM) in RGMII mode and Two-Supply Configuration. I'm using VDDIO 1.8V
I've a question on power sequencing,
VDDA2P5 - 2.5V
VDD1P1 - 1.1V
VDDIO - 1.8V
Can I supply /ramp-up all the voltages at the same time (VDDA2P5,VDD1P1 and VDDIO 1V8 at the same time)
or
Should I follow the Datasheet recommendation, i.e. VDDA2P5 and VDD1P1 are ramped up together and VDDIO(1V8) later.
Please confirm.
Thanks.
