AD983x Datasheet errata / inconsistency?

Hello, I'm designing a small board around some DDS modules (the AD9833 and AD9837) and think I've noticed a small inconsistency in both datasheets (and probably any others that are based off the same template) found on your website. The Pin Function Descriptions table suggests that VDD should be decoupled from AGND using a 0.1 uF and 10 uF capacitor, while CAP/2.5V should be decoupled from DGND with a 0.1 uF.  However, the evaluation board schematics have this reversed: VDD is decoupled from AGND with a 0.1 uF and CAP/2.5V decoupled from DGND with a 0.1 and 10 uF capacitor. Granted, they're 'just' decoupling capacitors, but I thought I'd bring it to your attention nonetheless.  Thank you!
