As far as the RK3328 data sheet is not available, everything is guessed.
Perhaps the PHY driver/receiver part is designed for use at 1.8v.
If so, termination to 3.3v is risky.

I am not able to find that voltage regulator Sad

For 1.2V yes, for 2.5V also, but for 1.8V NO, three shops told me already they had none. I am thinking about trying with the 1.2V model, I'll have to recalculate the resistors values. I have also a question regarding the caps for the regulator: why do they have different values? The example schema accompanying the voltage regulator suggest to use the same value for both caps. Why yours are different?

Thanks.
