AVS Functionality in DM816x / AM389x

Other Parts Discussed in Thread: AM3894

Hi,

We are using DM8168 and AM3894 in our design. We have following queries:

1. Can we use fixed voltage for AVS supply or is it compulsory to implement AVS supply with different scalable voltages?

2. What is the fixed value that can be used for step 1 and how it is determined?

3. Can we use the single regulator for both DM8168 AVS supply and AM3894 AVS supply or shall we use two separate regulators?

Thanks in advance.
