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  
MIL-STD-883 Method 1008, Cond,.B  
MIL-STD-883 Method 1010, Cond, B  
MIL-STD-883 Method 2001, Cond, A  
MIL-STD-883 Method 1015, Cond B  
(125°C for 168 hours with bias)  
5. Fine Leak  
6. Gross Leak  
MIL-STD-883 Method 1014, Cond. A1  
MIL-STD-883 Method 1014, Cond C  
7. Electrical Test at 25°C and temperature extremes, as follows:  
A. Frequency  
B. Current  
C. Rise Time  
D. Fall Time  
E. Duty Cycle  
F. Duty Cycle  
G. Frequency at 3.6V  
H. Frequency at 3.0V  
I. “Zero” logic level  
J. “One” logic level  
K. Tristate  
Test Data on each unit is available for additional cost
