Looking for clock source: 24.576 and 11.2896MHz

[FlexBen]

Hi,

I'm looking for a clock source for an Asynchronous SRC project. I want to cover both 44.1 and 48kHz (and multiples of that), so I'll need at least two master clock frequencies: 24.576 MHz and 11.2896 MHz
So far I found the Texas Instruments PLL170x-Series (Link) which has an unnecessary amount of features and takes a lot of PCB space.
I also came across the PhaseLink PLL601 (Datasheet) which would be perfect, but it seems to be either vaporware or discontinued, as I can only find "preliminary" datasheets and I can't find a distributor.
I cam across the term "PicoPLL" when googling, but that shows no search results at mouser, digiKey, Farnell...
So if anyone has a suggestion for a non-discontinued clock IC that generates the desired frequencies I'd very much appreciate it.

Edit: Maybe this fits better into the digital line level subforum? Im not sure, so: Dear Mods, please decide 😉

Maybe a digital 2-to-1 multiplexer and whichever of these is most convenient for you

Thanks for your reply. Using two oscillators and a mux really seems to be the best available solution.

Try this:

Which is a programmable synthesizer with three different outputs. Requires some assembly, but that is not hard. Programming is archaic and tedious, but effective. Cost is low, $18. Probably not important for your application, but it can be GPS disciplined.
