i.MX8 QXP PCB

Hi,

The IMX8HWDG document has the following general design recommendations:

3.4.6 LPDDR4-2400/3200 general design recommendations
Use PCB materials with good dielectric constants ( < 3.7 @ 5 GHz is desired). Some examples are Megtron6, Megtron4, ThunderClad2, and MCL-HE-679G Type(S).

However, to reduce the unit cost, I want to use PCB (185HR) with < 3.88 @ 5 GHz.
Can you give me your opinion on the above?

Hi @kyoungjin ,

I have confirmed it with our design team that, no problem you can use it:

no problem to use 185HR in imx8QXP design, actually we are using 185HR in our imx93 EVK design..

Hope this can do help for you
