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 Jim Adney wrote in message . ..

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? - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
