PECL = positive-supply ECL. It's set up to run from a +5V supply
(with the metal case grounded), instead of the usual -5.2V for ECL.
Has nothing to do with Plessey.

I believe it's spec'd +/-20ppm total from -40C to +85C. It uses a
standard AT-cut crystal, I believe, so one could find a zero-slope
operating temperature and it'd be quite stable.

Cheers,
Tom

Suggestion: just get a 100MHz TTL oscillator. I believe Harold
offered you one last time you posted about 100MHz xtals a couple years
ago. ECL won't have 2.5V output, but I could supply you with a nice
little PECL 100MHz VCXO that you could easily trim to "exactly"
100MHz. It will deliver about 800mV p-p into 50 ohms.

What is PECL?

What kind of stability and aging could I expect from this oscillator?

Yes, you are correct. Plessey used to make it. Please excuse my confusion.
