I use i.mx6q as my cpu,now i want to use RGMII,and i know its working electric level is 1.5V.
The RGMII IO link to a ETH Switch,but the ETH Switch is working at 3.3V,2.5V or 1.8V.
How can i use the RGMII at this situation?
If a level bidration trasformer is needed,can you give me a chip type？
Thank you very much.
