I’m using AD9102, I write and read in all register but I haven't output signal.
What is the minimum registers configuration for generate a signal?
Can it work without calibration?
In attachment the schematic.

Hello Larry,
Yes it is true the paragraph discusses RAMUPDATE, but there is no example of a minimum control sequence in the data sheet, which I think many users would have found helpful (as evidenced…
Hello Larry,
I also seem to have two other problems.
1. DDS Clock Source
I cannot make the DDS_MSB_EN work in the DDS_CONFIG register.
My assumption is that if I program the RAM to have two values…
Hi Larry,
I have the same problem. Trying to generate a Triangle wave with 78,125 KHz, 156,25 KHz, 312,5 KHz, 625 KHz, 1250 KHz, but I could not find any thing about the frequency for Triangle or Sawtooth wave.
I use the example2_4096_ramp.txt and example4.regval file, then I have changed:
the WAVE_SEL1 0x027[5:4] to 1
the SAW_STEP1 0x037[7:2] to 4.
So I have no idea how to change the frequency.
Actually, for the sin wave, I could easily change the frequency, by changing the DDS frequency in the DAC1 tab.
but for the Triangle wave, is vague.
