Change frequency

Question

Hey, I am using AD9106 and trying to change the frequency. In datasheet there is two registers 0x3E and 0x3F who are the responsible for wave frequency ,i changed that but still get constant frequency. so, my question is why it give constant frequency and how I can change it??

Hi MRD18 ,

To generate sawtooth waveforms, there are 2 options: (a) use the on-chip sawtooth generator or (b) use the on-chip SRAM.

If you want to use option a, refer to FAQ17 in AD9106 / AD9102 Low-Power DAC and Waveform Generator: FAQs

If you want to use option b, refer to FAQ 10 in AD9106 / AD9102 Low-Power DAC and Waveform Generator: FAQs

Shine
