  • AD9857: Producing a sinc wave with DDS

    I want to buy a DDS Model AD9857. In features description is written -
    SIN(x)/x correction (inverse SINC function)
    Does that mean that I can also produce a sinc signal with this DDS?

     

    No - there is a sibc filter correction for the DAC build in…

  • AD9857 PDCLK coming as banded in quadrature mode

    Hi,

    I was working in quadrature mode at 200 msps with ref clk 50Mhz using pll multiplier . I have configured the registers accordingly and even got the output successfully with shifting but later on the output was not fine and checked the pdclk it is…

  • A way to synchronize multiple AD9857

    Hello,

    I am trying to work with two of AD9857 DDSs in a synchronized way.

    In order to do that, at the same time, REFCLK, DATA, etc,

    The problem I find is that latency of output will differ 1 PDCLK  as Figure 33 and Figure 34 in the datasheet,

    Is there…
