Hi The ideal OCXO would be one at 33.333333 MHz. I suspect you will have a hard time finding one, short of a special order build. That's going to take time and cost money (trust me on that ...).
A reasonable alternative is to grab what ever frequency you have and use a clock multiplier / divider (like an ICS 525). If you have everything in one stack then you *might* be able to use a single frequency source. That's probably not a real good idea from a reliability standpoint ...
