Clock spurs at CC2520 output

Other Parts Discussed in Thread: CC2520

We are experiencing spurious output from the CC2520. The spurious is located on either side of the desired carrier at harmonics of the crystal frequency. Our crystal frequency is 32 MHz. The most offending spurs are 2X times that frequency (+/-64 MHz) on each side of the carrier.   

Are there any CC2520 register settings or other tricks we might employ to lower those spurs? We've got the part laid out pretty much according to the reference design. We've decoupled the power supply lines per your recommendations as well. 

Any thoughts?
