Everything You Need to Know About VCXO Oscillators

If you are looking into frequency control products, it’s important that you get your hands on the best supplies possible.

To this end, you will need to learn a little bit more about oscillators.

There are many different types available — to include Voltage Controlled Oscillators (VCXO).

There are many contractors that deal in VCXO components, so you’ll need to understand the key points.

For a primer on VCXO, read on and consider these points.

An Overview of the TCXO Oscillator

Crystals have long been used in watches and clocks because of the high level of dependability and accuracy they have. Crystal based oscillators like a TCXO use a vibrating crystal to ensure that electrical signals remain precise. They are a stabilizing tool that can help ensure a precise clock signal when included in digital circuits.

Weather, humidity, air pressure, or vibration can upset the accuracy of the frequency produced by crystals. That’s where temperature-controlled crystal oscillators (TCXOs) come in. They can help ensure a level of short-term stability during moments of interference.

The OCXO Oscillator: Everything You Need to Know

From mechanical vibrations and heat build-up, it’s time to choose stability over the status quo crystal usage. Here’s how an oven-controlled crystal oscillator can offer you optimal performance and a stable frequency:

Over-controlled crystal oscillators are used in situations that need the highest degree of stability. The OCXO is also called a temperature-stabilized crystal oscillator.

There are a few OCXO options that show a very high degree of stability, even as the outside temperature drops and rise at varying degrees. The oven-controlled crystal oscillators come in a bunch of different styles and packages. You’ll be able to find the perfect fit you.

Each package will have a different cost based on the type of oscillators in the bundle.

The Advantages of a Crystal Oscillator

advantage of crystal oscillatorsDo you prefer a quartz watch or a mechanical watch? You might hear some watch aficionados say that quartz watches have no soul or artistry. But one thing that they can’t deny is the superior accuracy of quartz watches. The secret to the accuracy of quartz watches is none other than the quartz itself. The quartz is the centerpiece of a crystal oscillator inside the watch. This electronic circuit produces precise electrical oscillations from the quartz’s piezoelectric property. This handles the clock’s timing signal.

There are other types of electronic oscillators such as the RC and LC oscillators. In timing circuits, crystal oscillators have the edge. Learn more about the advantages……

3 Factors That Affect Oscillator Frequency Stability

oscillator frequency stability

Your windows are down, your FM radio blares AC/DC at the highest volume, when all of a sudden, right in the middle of the guitar solo, you hear the sleep-inducing sounds of NPR. Don’t worry, you’re not going crazy. You’ve just encountered drift, an unwanted offset of an oscillator’s ideal frequency.

Drift often points to negative frequency stability. It’s not a big deal when it comes to radio broadcasts, but it plays a critical role in radar and satellite accuracy, where there’s little room for error.

But what affects stability in the first place? Many factors have a hand in oscillator stability. We’ve picked out the top three culprits. We’re going to show you how they affect stability and what you can do to control them.
