IMX6 RGMII voltage tolerance

Hi, Experts

We have a AR8031(PHY) which RGMII IO voltage(VDDIO_REG) is 1.8V, and the IMX6 use the 1.5V for the NVCC_RGMII.

AR8031 RGMII IO voltage seems could not be set to 1.5V.

My question is, could the IMX6 1.5v RGMII interface compatible with the PHY's 1.8V ?

Thanks!

Hi mcggoal

 

one can look at datasheet of used device, for example for i.MX6Q 

i.MX 6Dual/6Quad Applications Processors for Consumer Products - Data Sheet

so for PHY's 1.8V  it is necessary to use NVCC_RGMII 1.70V-1.90V
