RTIO clock frequency for Kasli (cu3)

ngkiaboon

Hi, I wish to lock my Kasli on the cu3 variant to our 10 MHz master clock. I will be following the instructions on this post on another thread and here and here, but it is not entirely clear to me (from source here) whether it takes in 125 MHz or 150 MHz, or if it does not matter as long as it is one of the two.

Also, I may be misunderstanding this post, but it seems to suggest that I could feed my Kasli a 10 MHz from my master clock and let it derive 125 MHz internally with some binary; if so I would like to save on $1.5k for the Wenzel VHF PLO, and proceed with this instead (I hope I am still under support).

Please advise, thank you!

You can use the Si5324 built into the Kasli and/or the AD9910 PLL to convert the 10MHz to respectively 125MHz and 1GHz. The phase noise performance may not be as good as with Wenzel units though.
