Power supply decoupling recommendations for i.MX7D/S

Hi all

 

Let me confirm about power supply decoupling recommendations for i.MX7D/S.

According to the latest Hardware Development Guide for i.MX7D/S, the following comment is in the table 8.

 

When VDD_SNVS_IN is not powered by a battery, it is recommended that VDD_SNVS_IN = VDD_IP8_IN.

 

 

I want to ask above comment.

 

Q1.

I can't find VDD_IP8_IN signal. Is this VDDA_1P8_IN ?

 

Q2.

If Q1 is yes, I think it can't connect together because the operating range is different as below.

 

How can user connect ?
