Step-by-Step Guide: How to Choose an OCXO in 2020.

If you're in the market for an Oven Controlled Crystal Oscillator (OCXO) in 2020, there are a few key things to keep in mind before making a purchase. Here are four important tips to help you make an informed decision.

Step 1: Consider Your Application.

The first step in selecting an OCXO is to consider your application. OCXOs are commonly used in precision timekeeping, frequency synthesis, and signal processing applications, among others. Depending on your specific requirements, you may need an OCXO with very low phase noise, high frequency stability, or other specialized features. Take the time to carefully evaluate your application and determine which OCXO parameters are most important for your needs.

Step 2: Evaluate Frequency Stability.

Frequency stability is a critical parameter to consider when choosing an OCXO. OCXOs typically offer frequency stability on the order of parts per billion (ppb), with some models achieving stability as low as a few parts per trillion (ppt). Look for an OCXO that offers the level of stability required for your application.

Step 3: Assess Phase Noise Performance.

Phase noise is another important parameter to consider. It is a measure of the spectral purity of the output signal and is critical in applications such as communications and radar. Low phase noise is especially important for applications that require high sensitivity or low signal-to-noise ratios. To ensure optimal performance, look for an OCXO with low phase noise and good spectral purity.

Step 4: Choose the Right Package.

Finally, you will need to choose the right package for your OCXO. OCXOs are available in a variety of packages, including hermetically sealed metal cans, surface-mount packages, and more. Consider factors such as size, weight, and environmental requirements when making your selection.

By following these four tips, you will be able to choose an OCXO that meets the needs of your application. With careful consideration of key parameters such as frequency stability and phase noise, you can ensure optimal performance and reliability for your system.
