Hi all

 

I want to know the RGMII can use in 3.3V mode in i.MX6SoloX.

Could you tell me i.MX6SoloX can use 3.3V for RGMII ?

 

I checked "Absolute Maximum Ratings" and "Operating ranges" in following datasheet.

http://www.nxp.com/assets/documents/data/en/data-sheets/IMX6SXAEC.pdf 

 

The absolute max ratings of NVCC_RGMII is as below.

 

On the other hand, the operating ranges of NVCC_RGMII is as below.

 

Furthermore, I checked the schematic of MCIMX6SX-SDB (MX6SoloX SABRESDB_DESIGNFILES/Schematics/SPF-27962.pdf.pdf).

In device tree of SPF-27962.pdf.pdf, it seems like the NVCC_RGMII is inputted 3.3V.

 

 

As a result, I think the description of Absolute Maximum Ratings for NVCC_RGMII in datasheet is typo.

Am I correct ?

If my understanding is correct, please tell the correct value.
