Sampling rate of AD9081

Question

As per my information, ADC of the EVAL-AD9081 has a maximum sample rate of 4GSPS. 
 At what other sample rates, we can operate this card? 
 Is it possible to operate this card at 1GSPS or less sample rates?

Hi Waqas_Rehman, 
 You can see the supported modes for the AD9081 in the following user guide: https://www.analog.com/media/en/technical-documentation/user-guides/ad9081-ad9082-ug-1578.pdf (starting from page 94). There is also example " Example 5: 4D2A Single Band, DAC in 1 GSPS I/Q Mode, ADC in 1 GSPS I/Q Mode" at page 239. 
 Please note that you will need to modify the JESD parameters & clocks in the devicetree, the JESD parameters inside the system_project.tcl file and (possibly) the timing_constr.xdc file with your clock values before building the HDL. 
 Regards,
