RF engineers are aware that temperature variations are the most significant factor contributing to frequency drift in crystal oscillators. Other variables affecting frequency output, such as humidity and pressure, can be easily alleviated with a hermetically sealed packaging of the crystal in a vacuum, or in an inert gas such as nitrogen. Controlling temperature for precise frequency output in a crystal oscillator circuit, however, requires a higher level of electronic RF design ingenuity. Enter... The Oven Controlled Crystal Oscillator (OCXO).

RF engineers would love to get their hands on an ideal crystal oscillator, one which transmits at the designated frequency for the life of the device without any deviation under all conditions. Unfortunately, that ideal circuit world is a mathematical fantasy. There are many factors that contribute to oscillator stability and frequency drift issues. To prevent these problems as much as possible, having a firm understanding of frequency stability will help give you the tools to keep your applications performing optimally. But there's another problem...

Here’s the scary thing…

Even if you sit for hours upon hours trying to set a precise initial frequency of an oscillator, it’s still going to drift and the oscillator will not be able maintain that frequency over the full course of its use. In this post, you’ll learn the MANY sources of frequency instability and why an Ultra-Stable OCXO may be the fix-all solution.
