We are designing a new board which includes AD9625 on it and we are trying to base our design on evaluation board cause right now the documentation for this product is rather limited. So I was looking to AD-FMCADC2-EBZ FMC Board and Ive noticed that all capacitor used in high frequency clock coupling are of the GRM033R60J104KE19D series. This is a general purpose capacitor that it doesn't have good characteristics in high frequencies and might not behave like a capacitor in high frequencies. So wouldn't be better if we used instead a capacitor with the same rating but with better characteristics for high frequencies like this one for example 550L104KTT American Technical Ceramics | 1284-1001-2-ND | DigiKey
