DAC3171: Layout question

Part Number:DAC3171

Hi,

in my current design, I'm using DAC3171. 

I see some spurs when TX with the DAC 

when I checked my Layout I saw that there are some differences between what I did and what is shown in the EVM layout 

I wish to understand if the reason for the Spurs can be that 

please see my layout attached below.
