Symmetricom's 9940 series of XO's utilize proven designs and hybrid construction to provide high performance in space applications that require minimal size, weight and power.
The 9940 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.
