i.MX8M Mini power supply rail @ 1.2V

Hi,

For the i.MX8M Mini processor EVK, the power rail VDD_MIPI_1P2 take the input fom PMIC BD71847AMWV, LDO6 1.2V output (net name- VDD_PHY_1V2).

 

MIPI supply in my custom board design works on 1.8V  (VDD_MIPI_1P8), as per understanding

 

- VDD_MIPI_1P2 supply for MIPI interfaces will not be needed so can be kept as unconnected nets.

- are there any other internal processor blocks that will need 1.2V supply?

- I need to interface an ethernet PHY which needs 1.2V and 230mA current. can I route this supply from PMIC BD71847AMWV ?

 

Please confirm on above and advise on above queries.

 

Thanks,

Dhara
