for superior aging and field performance
. Crystal angle controlled to ± 0.5 minute for excellent
temperature stability
. 168 hour class B burn-in and extensive
environmental testing for best performance in
rugged field environments
. Guarantee start-up with ramping DC supply
. Start-up time <5ms, typical
Part Dimensions (max): 7.7 x 5.2 x 1.9 mm

Description
These high reliability oscillators provide HCMOS clock 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. The calculated MTBF is 3.8x106 at 125°C.
