You can always play the old bipolar trick
---->|---->|--- . Two diode drops on the outputs - if you parallel termination at the receiver - will level shift to the new level. Just work through the numbers to make sure you terminate to a value that guarantees current always flowing out of the emitter followers.
Going from 3.3 - 2.5 only requires one diode per output.

Subject: [SI-LIST] : PECL TO LVPECL
Anybody know of 5V PECL to 3.3V LVPECL Translators - single or dual
translator. I know ON Semi - MC100LVEL92 and Micrel - SY100EL92 make one,
but these are triple translators.
