描述 Description

Hybrid Space-Qualified Crystal Oscillator (XO)Microsemi's 9922 series of?cyrstal oscillators (XOs)?uses proven designs and hybrid construction to provide high performance in space applications that require minimal size, weight, and power.The 9922 series?uses 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 ManufacturingThe 9920 series designs are based on Microsemi's 35-year heritage of design and manufacturing techniques proven for reliability in numerous space applications. The hybrids?are manufactured in a MIL-PRF-38534 class K facility in a class 100,000 clean room that ensures maximum reliability.Ruggedized High PerformanceThe 9920 series has demonstrated excellent performance after exposure to high levels of shock, vibration, and radiation, consistent with the rigorous requirements of space applications.Key FeaturesStandard Output Frequency 600Mhz10 MHz to 1.2 GHz output frequencyInitial accuracy +-10ppmMIL-PRF-38534 Class H or K certifiedSine wave or PECL outputsLow aging and phase noiseRadiation hardenedEnvironmentally robust
