AD9642 digital output driving strength?

Dear Experts,

I have several questions regarding the driving strength of digital output of AD9642, whose product info is in the webage below.

* Is there any requirement/recommendation on the digital output trace capacitance, for 250 MSPS scenario?

* What is the max current that each digital output pin can drive?

Thank you.
