Functional Description:

The LGH300 Ultra-Low-G product family, incorporates Esterline Research and Design’s patented MSAC compensation architecture within an ovenized oscillator temperature control system.  This compensation achieves frequency stability performance of less than ±0.25 ppb over the temperature range of -40°C to +105°C.  The LGH300 design platform can deliver acceleration sensitivity performance of less than 0.01 ppb/g, translating into minimal phase noise degradation under vibration.  


The LGH300 also offers other unique and performance enhancing features.  Vastly superior turn-on characteristics as compared to traditional OCXO product offerings, with turn-on stability within +/-100 ppb of final frequency after 1 second of operation are achieved.  Wide pull ranges up to +/-1000 ppm, and superior aging options as low as +/-50 ppb over 10 years life are also ordering options.
