I have those 9954/9854 boards and the problem is the drivers for newer operating systems past XP aren’t available. The AD9854/9954 boards were clones of the AD eval kits and you downloaded the eval kit software from AD. I got the board(s) working with Windows 7 but it took a lot of screwing around. I never got it working with Windows 10. The other issue with those boards are the filters were set really high. All DDS units need a filter on the output though I’m sure the term “all” can be debated.
If you have a need to generate a quadrature signal and have access to Windows 7, or better yet, XPSP3, then yes, it is a decent option and seemed to work well. The filters can be handled off-board, especially if you just need 10Mhz as BG7TBL has decent 10Mhz filters for $10 per. I bought a couple and hung them on my RFTG-U REF0 and REF1 outputs and they make a really nice 10Mhz sine wave.
