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.

Thanks,
