Abstract :
Recently the significant increase of demand for Ultra Stable Quartz Oscillators has been evidenced. Such oscillators are used for many applications including CDMA, GPS/GLONASS, etc. The following major requirements are usually applied for these oscillators: frequency stability vs. temperature changes of ±(1-2)×10-10; long term stability of ±(1-2)×10-8 /year; short term stability of <5×10-12 for time intervals of 1 through 100 seconds. As the world experience shows, very tight combinations of requirements can be met in Double Oven Crystal Oscillators (DOCXOs). However, development, production and measurement of such DOCXOs is a quite technically complicated task.
