DP83867IR: Figure 1. Power-Up Timing

Hirotaka Matsumoto

Part Number: DP83867IR

Hi all

Would you mind if we ask DP83867IR?

Figure1 on the datasheet shows power up sequence.
We would like to confirm meaning of VDD.

What does "VDD" indicate - VDDIO, VDD1P0 or VDD2P5?

We assume that VDD indicates VDDIO, because strap setting is relation to VDDIO level.
Is our recognition correct?

Kind regards

Hi Hirotaka Matsumoto

This diagram is in regards to the analog supply not VDDIO. Depending on which analog supply goes up last that should be the timing it is referring to.

Thanks,

Cecilia
