Description
These high reliability oscillators provide
PECL/LVDS waveforms 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 oscillator. 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. The calculated MTBF is
3.8X10
6
at 125°C.
