Sampling Clock of AD9208

I am using AD9208 with ADS7-V2EBZ.

I have some questions about sampling clock of AD9208.

In the datasheet of AD9208, the sample rate 2500(Min)MSPS ~3100 (Max) MSPS.

 

Then, below 2500MHz(0~2500MHz) can't I use this ADC properly?

But, based on my experiment, when I set the 1GSPS or 2.4GSPS or something below 2.5GSPS as sampling clock,

the SNR & SFDR of ADC is very good.

 

the value of datasheet(2500MSPS~3100MSPS), what standard is applied?

 

Thanks~!
