I am trying to drive the ad9958/ad9959 with the software and an external reference clock. For the application I have in mind I would need a good output at higher frequencies. I tried to output 100 MHz, but the output seems really bad. Is there something I am missing that is necessary for higher frequencies output?
What is the frequency of your external reference clock? Also, can you share your evaluation software settings so we could assess it?
The external referance clock was at 25 MHz. The file was a preconfigured file that set the cannels to 10,20,30 and 40 MHz.
I somehow cant load the file into the message here :(
