I just started using ad9954 and would like to ask some basic questions.
I want to get the frequency in the output to keep changing (after comparator).How should I set up part of the software?
What else is needed on the evaluation board?
Kindly refer to the image:
For basics, you can use the Linear Sweep feature ( can be controlled via RAM/Linear Sweep Configure dialog box) where you can have LFM between two frequencies. Since you are interested in frequency hopping, you are most likely to use the RAM File Editor where you can chose frequencies to output at certain time intervals.
In the hardware, you need to supply the AVDD with 1.8 V and DVDD with either 1.8 or 3.3. The REF_CLK input shoul also be supplied with a clock with a max frequency of 400 MHz and with a power of 0dBm.
