MAX98091 MCLK : 58.9 MHz freq's EMI Issue

Hello, Mahammadirfan,

This is a novel combinations of clock frequencies to me, but I'll try to help as much as I am able to.

Would you be able to share how the MCLK line is routed on your PCB?  Many times higher EMI can be caused by long trace length or incomplete shielding and can be solved with PCB routing.

I can look at some other things, but first I would like to review the current layout.

Regards,

Ed

Hello,

We are still facing this issue , even after the changes we did in the layout for shielding and reference planes.

Please share me your email ID where I can share the Layout for your review. 

Thanks

Hello, Mahammadirfan,

You can send me your layout at ed.sellers@analog.com.  I would be happy to review it and see if I can see any potential causes of the excessive EMI.
