The datasheet for the AD9102 chip has an example of an fsk modulated signal generated using DDS tunings words and SRAM. However, I was unable to achieve this by modifying those registers. Would someone be able to help me navigate how these changes will shape the waveform and what I need to do to produce a waveform similar to the one in the given example?
I moved your thread to the High-Speed DACs community. Someone here will be able to assist you.
