A fair question... in fact I was initially planning to use the ABLNO + a PLL. The OCXOs I found, however, are CTS VFOV405's with phase noise claimed to be just as good as the ABLNO or CVHD VCXOs: https://www.ctscorp.com/wp-content/uploads/VFOV405.pdf They are reasonably low power, small[-ish], and have adequate stability for my needs. You can see why it is tempting to make the multiplier scheme work, as it should save on both power and board area. (The target application is a battery-powered SDR.) So far there don't seem to be any show-stopper issues with the plan, except that I am going to have to put together a phase-noise measurement system, or find a friend with one.
Have you checked delivery times? - Just because it's listed in the catalog does not mean you can get it in the next few weeks or months. If the online sources (Digikey, mouser, Newark, etc.) have them in stock, then you're good to go, but otherwise you could be looking at 6 months or more.
