Hi,

I am working on AM4379 based design.

I have to do the power analysis of my architecture.

Anyone can share the link of AM43xx Power Consumption Summary application report.

Hi,

I have one doubt in am437x design that is in giabit ethernet phy chip design.

As per datasheet of KSZ9031RNXCA (phy chip) AVDDl,DVDDL and AVDDL_PLL maximum voltage is 1.8V.

But in the design applied 3.3V through P channel mosfet.

I know it is working fine in EVM .

Is there any reason to give 3.3V. Below is the design

The external P-channel MOSFET, Q6 is a 1.2V regulator for the low voltages required. See the application note: www.micrel.com/.../ANLAN206.pdf page 3.

Dear Biser,

Can you share the latest PET for Device rev PG2.1.

Because Device rev PG1.1 support up to 600MHz only.

I need the PET for 1GHz.
