Hi; 

 

Why the sampling rate of  ADC LOWER THAN DAC. 

4DSP FMC150 High-Speed ADC/DAC FMC Module 

250 MSPS Analog to Digital converter (ADC)

800 MSPS, 2x/4x interpolation Digital to Analog converter (DAC)

because DACs are easy and ADCs are hard so making a DAC go faster is easier than making an ADC sample faster. Also with a faster DAC, it is easier to generate the signal you want without extra analog filtering at the output.
