Hi there,
I have a question about the 3-supply power-up for the DP83561. The datasheet shows the preferred method is to power up all supplies at the same time, however, in our case, the +1.1V supply is the first to ramp up, and is stable for up to 7.7ms prior to +3.3V(VDDIO)/+2.5V being stable. +3.3V and +2.5V ramp up at largely the same rate and time. Will this cause an issue?
I have a second question about how the datasheet states the startup time for all supplies should be between 0.5ms and 50ms. In this design, the +1.1V supply ramps up between 38.5us and 121.15us. Will this be an issue?
Thank you for your help!
