Features
Description
High speed – Low jitter LVPECL or LVDS output with
tristate
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
3.8X106 at 125°C.
Small SMD package (5X7 mm)
Stability options from +/-25ppm to +/-100ppm
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
Tristate option available
Serialized test data available
Calculated MTBF is 3.8X106 hours at 125°C
