    Hi,
    
 
    I would like to use AD9102.
    
 
    So, I have two questions.
    
 
    #1  Is it possible to shift the phase of the waveform written to SRAM or to invert it?
    
 
          Is it possible by adjusting the register of DDS_PHASE?
    
 
    #2  If it is possible to shift the phase, is it possible to issue a sinusoidal wave whose phase is continuously delayed by
    
 
    　  180 ° after issuing a sinusoidal wave of 0 ° phase?
    
 
    Best Regards,
    
 
    Yuya

      Hi -
      
 
      1. It is possible to invert SRAM generated waveforms using the DAC_DIG_GAIN variable at address 0x35. DDS_PHASE does not act on SRAM data. It controls the phase of the DDS output.
      
 
      2. Continuous DDS phase shifting is possible using the DDS_PHASE variable with the DDS generating the waveform.
      
 
      Thanks
