    Hi team,
    

        
    

    

                  We are trying to develop the driver for AD9213 with VCU118. Since there is no reference design and API's for AD9213 , we take AD9208_VCU118 as a reference design. We are using AD9213 at 12.5Gbps lane rate with L=16, M=1, N=N' = 16, F=2, S=8, Fout =10Gsps.
    

                   
    

                  We are following the startup sequence in the datasheet to initialize the AD9213. We read and write the registers for AD9213 and it communicates with the FPGA. AD9231 PLL is locked but we are stuck in CGS state. What were the reasons for this CGS state? Could please guide us to drive JESD link status to "Data" state instead of this CGS state.
    

    

                     
    

    Thanks in Advance
