AD9783 evaluation board PCB layout

Hello,

 

we designed our instruments using your digital-to-analog converter AD9783. Our PCBs are inspired by your AD9783-DPG2-EBZ evaluation board. We would like to know what is the design driver of the 10pF capacitors (appended to the IOUT1N/P and IOUT2N/P pins) with the ground trace underneath (in EBZ schematic denoted as C8 and C9)? What is the background of this technique? We ask since we want to use your DAC part in the most performing setup, not sub-optimally.

 

Best regards,

Michael
