AD9914 vs AD9915

Is there actually any differences between the ICs of AD9914 and AD9915 parts or are they just binned?

Is the SFDR spec on the AD9915 (-57 dBc) better than the AD9914 (-50 dBc) because the clock rate is lower, or because they are manufactured differently? (i.e. Will I get the -57 dBc SFDR out of the AD9914 if I lower the clock rate to the range of the AD9915?)

 

The reason I ask is because I've design a board for the AD9914 and in some case will be using a lower frequency clock (~2.5 GHz), so I was wondering whether I should populate the board with the AD9915 part in that case or if I can just always populate with AD9914 to cover higher and lower clock rates.
