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 Bart –
I tried this in the lab just now. It turns out the DDS output MSB can only be used as the SRAM address counter clock if the DDS Tuning word source is set to RAM data.
