Hi All,
I am trying to generate a simple Sine wave from DAC5672 on my Hsmc daughter card from Terasic . The NCO i am using is from Open Cores , i works fine in simulation as shown in screen shot attached , But when i connect my scope probes i get distorted output screen shot attached . The DAC and NCO are provided with 100Mhz clock and the required output is 12Mhz , which is in my case is 12Mhz but distorted .
When is connect a simple upcounter , i get a Saw tooth wave output as expected .
Has anyone solved this problem ? is there something i am missing ?
