What is the absolute maximum voltage for NVCC_RGMII on the imx6 DQ SCM? - part number = MSCMMX6DZCK08AB1G0A

Hi Paul

max. i.MX6DQ processor voltages are defined in its datasheet

Thanks Igor. In the datasheet there is no listed absolute maximum listed in table 4 for NVCC_RGMII. I do see the 2.25V - 2.625V recommended operating voltage range listed in table 6. I would like to know if that is the "absolute maximum" voltage that can be applied to the NVCC_RGMII rail without damaging the SCM.
Regards
Paul

Hi Paul

it is 2.625V according to Table 6. Operating Ranges
http://cache.freescale.com/files/32bit/doc/data_sheet/IMX6DQCEC.pdf

it is also considered as "Absolute Maximum Ratings".

OK - on a related question - in the Solo X datasheet table 6 the absolute max for NVCC_RGMII is shown as 2.725V. Then in table 10 the operating voltage range shows a 3.3V mode for NVCC_RGMII with a 3.6V max. Does Solo X support a 3.3V RGMII mode?

In previous i.MX6SX Datasheet (rev.1, 9/2015) absolute max for NVCC_RGMII was 3.6V.

I would suggest new thread for this.
