    Thread Summary
    
                The user asked if it's possible to generate a quadrature oscillation output (sine and cosine) using two AD9833 chips. The solution involves sharing the same MCLK and SPI, initializing one chip with a 90° phase shift, and asserting both CS lines simultaneously when writing the frequency word. The AD9106 was suggested as an alternative with a similar interface, but the user must use AD9833.

    Is it possible to create a quadrature oscillaion optput from two AD9833. I need changable quadrature signal, sine and cosine. What is the solution?
    

    

    I have seen this:
    

    Synchronizing Multiple AD9850/AD9851 DDS-Based Synthesizers Application Note (AN-587) (analog.com)
    

    But AD9833 does not contain W_CLK and FQ_UD.
