Description:
These high reliability oscillators provide LVPECL/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.
TABLE 1
Each unit undergoes the following:
1. Stabilization Bake
2. Temperature Cycling
3. Constant Acceleration
4. Burn-in
