Hello，I hope to use a AD9914 for linearly sweep, clk-in is 100MHz,N is12，so the system clock is 2.4GHz.
Then, I connect DRHOLD and DRCTL to GND..
The sweep frequency generated is 90MHz -- 100MHz, and the frequency step is 5KHz, Step intervals is 0.1us,
I hope to use No-Dwell high and No-Dwell low configuration, so it can sweep all the time automatic .
Here is my register configuration:
But finally, It just a constant 90MHz output， then I measured the pin 65 ( DROVER) , it is low ..
So what happend to my AD9914, I just hope to use it to realize linearly sweep or Where did I go wrong for my configuration or connection.. thank you !
