TUMA2: Design issues for frequency sources based on Precision Low Phase Noise Oven Controlled Crystal Oscillators.

Presentation Abstract
Precision Low Phase Noise Oven Controlled Crystal Oscillators with output frequencies from 10 to 100 MHz are the key reference sources for modern RF equipment. Phase noise, aging and frequency stability vs. temperature are the main parameters of OCXO to ensure the quality of equipment. But another important parameters like dynamic temperature sensitivity, vibration sensitivity (not only for moving vehicles) are being ignored mistakenly by the developers. What parameters may be important for? What are the phase noise limit for oscillators? What type of crystals we use and how they influence the oscillator’s parameters?
