What microcontroller to use to drive parallel ports of DDS ICs?

HI guys,

 

What micro-controller can be used to drive reliably the parallel ports of DDS ICs with the maximum of 250MHz possible?

(AD9858 and AD9910 provide a 250MHz that samples the parallel port).

 

Are there any uCs that are able to use this 250MHz clock to compute and program the DDS?

 

This would be an AllDigitalPLL application where one computes a new frequency and wants to update the DDS' FTW as fast as possible.

 

Regards,

Dorin
