9920
Hybrid Space-Qualified Crystal Oscillator (XO)
The 9920 series utilizes 3rd or 5th overtone AT cut crystals in a Colpitts configuration with optional multiplication circuitry and output amplifier or driver stages. The precision crystals are contained within hermetic or vacuum sealed packages housed within the hybrid circuit package resulting in the lowest end of life frequency drift possible. Output frequency, output waveform, and package style can be chosen to meet a wide variety of standard and customized applications.
Mil Spec Manufacturing
The 9920 series designs are based on Symmetricom's 35-year heritage of design and manufacturing techniquesproven for reliability in numerous space applications. They are manufactured in a MIL-PRF-38534C class K facility in a class 100,000 clean room that ensures maximum reliability.
Ruggedized High Performance
The 9920 series has demonstrated excellent performance after exposure to high levels of shock, vibration and radiation consistent with the rigorous requirements of space applications.
