Hi yashred ,

Thank you for your patience.

Could you kindly provide more details about the specific issue you are encountering? For the AD9739, you can refer to the Multiple Device Synchronization section in the datasheet (pp. 37-39) as it features a comprehensive discussion with supporting block diagrams on how to set up and connect multiple AD9739 DACs with an FPGA and achieve synchronization among the devices.

Is connecting master DAC DCO to FPGA enough or do we have to connect all the DAC's DCO to the FPGA.

Only the DCO of the primary DAC should be connected to the FPGA. This also applies to setups that use multiple FPGAs (see Figure 52 in the datasheet for an example).
