LVPECL or LVDS output with tristate
SMD package (5x7 mm)
Stability options from  25ppm to  75ppm
Leadless chip carrier package is hermetically
sealed for superior aging and field
performance
Crystal angle controlled to  0.5 for excellent
temperature stability
168 hour Class B burn-in and extensive
environmental testing for best performance in
rugged field environments
Serialized test data available
Calculated MTBF is 3.8X106 hours at 125°C
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.
