i.mx6q RGMII DATA IO LEVEL

[2233453742]

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.

Hello Ren Yunsai,

The RGMII module on the i.MX6Q can work at various voltages levels (1.5V, 1.8V, 2.5V) as you may see on the datasheet. That being said, if your design is set to 1.5V you would need to use a voltage level translator.

I cannot recommend on any particular one as we haven’t tested them with the i.MX6 but there are several on the market and NXP have several available.

I hope this helps!
