    Hi,
    

    I'm configuring AD9172 16bit, 1x interpolation (mode 11).
    

    I observed the following behavior: Sending by JESD all code samples in the interval [0x0000 to 0x7fff]  the waveform is correctly viewed in the oscilloscope.
    

    The same happens if code samples are in the interval [0x8000 to 0xffff]. 
    

    But if the samples are in [0x0000 to 0xffff] crossing the code 0x8000 the output is not correct anymore.  
    

    Is there an explanation?
    

    Thanks
