Power supply decoupling recommendations for i.MX7D/S

[ko-hey]

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 ?

Hello,

  Agree, considerations about VDD_IP8_IN (VDDA_1P8_IN  ?) in the Development Guide look strange.

  I've informed the team about it. 

Have a great day,
Yuri

Hi YuriMuhin_ng‌

It have been taken for over three weeks.

We can't continue the development.
