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.
We sat down with our very own Greg Rogers, VP of Products, at IMS 2017 this year to give you an up-close and personal experience with Greg and, more importantly, our g-sensitivity oscillators :)
One of the core challenges any RF engineer faces is maintaining frequency stability in crystal oscillators. In an ideal world, an oscillator would transmit at the desired frequency indefinitely and without deviation…but of course, we don’t live in an ideal world, and frequency drift is a real problem in many applications. There are a number of factors which can cause an oscillator to deviate from the correct frequency, but it is not an insurmountable issue, and there are various approaches engineers can take to improve stability. In this article, we will discuss approaches to maintaining a high degree of stability in crystal oscillators.
Engineering firms across all industries often have to work with many different suppliers to build their products. In the field of radio frequency tech, one of the most critical components in any design is the oscillator which generates the frequency itself. If the wrong type of crystal oscillator is used or it is of poor quality, it can ruin a design which is superb in all other respects. That’s why it’s so important to make sure that you’re working with a reputable supplier. In this guide, we’ll cover some essential questions any RF engineer should ask their crystal oscillator supplier.
In a perfect world, a crystal oscillator would generate a signal that remains steady, consistent and clear with no deviations, for as long as that signal needed to be transmitted. But of course, we don’t live in a perfect world, do we?
When High Stability is a Must
One Size Does NOT Always Fit Well
When it comes to crystal oscillators, one size does not fit all. Different applications have different power requirements, ranges of phase noise, tolerance for acceleration sensitivity, and more. As a result, different types of crystal oscillators have been developed over the years and are all used for many different applications.
