    Thread Summary
    
                The user is unable to generate a signal using the AD9102 despite writing and reading all registers. The solution involves setting the DDS Tuning Word source to RAM data and using the DDS MSB as the SRAM address counter clock. Additionally, the user must ensure the RAMUPDATE register is set to 1 to transfer shadow register values to active registers. The data sheet lacks clear examples and specific details, leading to confusion about the initialization sequence and register settings.

    I’m using  AD9102, I write and read in all register but I haven't output signal.
    
 
    What is the minimum registers configuration for generate a signal?
    
 
    Can it work without calibration?
    
 
    In attachment the schematic.
    
 
    Regards.
