And it is a few years old.. new oscillators come out all the time.


As Bob has pointed out, though, many, many oscillators (particularly 
ones with high performance) are essentially "customer spec" driven - 
rather than delivered off the shelf from the catalog.

With lead times of weeks or months, there's ample opportunity for 
tuning, selecting, etc.


For anything that costs more than a a few tens of dollars in single 
quantity, the catalog is often more "what we've built in the past".


If you look at spec sheets for a fairly common OCXO OX-220 from 
Microchip/Vectron
https://www.vectron.com/products/ocxo/ox-203.pdf

There's 2 output options, 3 temperature ranges,  3 performance grades, 
and 1 control option.

At least one version is available from Mouser for $85.

And I'm sure if I wanted to order one with something slightly different, 
Vectron would do it.
