Radiated emissions from Audio Clock

Hi,

I have a custom board with IMX6 and SGTL5000 with Audio clock running at 11.29MHz, there are emissions from the 6th, 7th harmonics from this clock. The clock is provided by GPIO00

I have tried increasing the drive strength and controlling the slew rate with no promising effect ?

Is there any thing to be taken care in the layout/ schematics for this audio codec routing ?

 

Thanks,

Ganesh
