Description
These high reliability oscillators provide LVPECL/LVDS outputs for applications subjected to the
most stringent environmental conditions. They are mechanically robust and weigh less than 0.2
grams. This 5x7 mm SMD package has a hermetic seal, thus ensuring the integrity of each part.
Each oscillator is burned-in at 125°C for 168 hours, temperature cycled and centrifuged then fully
tested in accordance with Table 1. Reliability tests are performed per Table 2.
