I'm using the DDS function of AD9858. I wanna get the sinewave signal with my desired frequency from DAC output. I adopted parallel programming mode and single -tone operation mode. I'm sure the microcontroller port has communicated with AD9858 because when the register, eg, 2GHz divider disable, was set, the SYNCLK output is 125MHz. I also set other registers. However, no matter how I debug, there is no output from DAC output.
If someone has ever used AD9858 or related, could you give me some suggestions?
Thank you very much!
