Inside Frequency Control

What if we told you that specifying more electronic frequency control (EFC) than you need could actually be hurting your company's wallet? Well, it very well may be!

Paying attention to whether your supplier is using AT-cut or SC-cut crystals will help you save money in the long run when it comes to oscillators. In this article, we'll review the difference between these two types of cuts and the impacts of EFC pull. 

Will a crystal oscillator operate outside its specified temperature range? This is a common question and the short answer is: yes, but it's complicated.

If, for example, a crystal oscillator is specified over 0 to 60 °C, it will most likely perform without any issues over -40 to 85 °C. But it's possible that it will fall outside its specified stability. This may not matter if the application needs just a stable frequency rather than an accurate frequency.

Poor manufacturing environments can significantly reduce the performance quality of a pressure transducer. A failing pressure transducer will lead to problems with sensors and will provide inaccurate readings (or none at all).

A faulty pressure transducer can not only cause frustration and waste time, but it can also lead to unnecessary costs.

To prevent pressure transducer problems or failure from happening in the first place, let's take a look at seven pressure transducer troubleshooting methods to keep your transducers and sensors working great!

Do you know all about atomic clocks in space and how they work? If not, it's about TIME you do. (Haha. Ha. Ha...)

Timing is everything when it comes to GPS satellites and other space applications. Even just a one-microsecond error in timing can lead to an error of 300 meters on the ground. Because atomic clocks can maintain very precise timing, they're a great solution for GPS and other LEO satellites.

We'll be honest, crystal oscillators aren't the easiest topic to understand. That's mostly because there's a wide variety of crystal oscillator types that do different things, in different ways, for different purposes. This is largely due to their almost endless applications. From satellite communications in space, to military & defense, to telecom and more... there are so many different needs for crystal oscillators. 

In this post, we'll cover the most common types of crystal oscillators, which include:

• Oven controlled crystal oscillators (OCXO)
• Temperature compensated oscillators (TCXO)
• Voltage controlled oscillators (VCXO)
• Clock oscillators (XO)
• And some other key types within these categories

I know it sounds like a lot to cover, but don't worry! We're about to make things a whole lot easier for you. By the end of this post, you'll learn the basic uses, advantages, and limitations of each crystal oscillator type.

“Good things come to those who wait,” as the saying goes, and while aging is a part of all life cycles, crystals shouldn’t age prematurely. The careful production stages and the time it takes to complete them are necessary to the efficient operation of OCXOs. 

One of the key things you need to know before purchasing a crystal oscillator is expected costs. There are multiple ways and specifications that can quickly drive up (and down) the costs of OCXOs and other crystal oscillators. In this post, you'll learn the top 8 cost drivers for crystal oscillators in order of most influential to least influential.

By the end of this post you'll have a much better idea of where to focus your cost-cutting efforts and to save the most in the long-term. Much of it just depends on your specific application and needs and where you're able to be more flexible.

Have you noticed how difficult it seems to find transparent pricing for frequency control & crystal oscillator components? If so, you're not wrong. Traditionally, it has been difficult to find quick, standard pricing for all things frequency control. Instead, you're basically forced to go through the long quoting process to even get an idea of expected pricing. So why is this? In this post I'm going to explain why OCXO oscillator pricing has been traditionally hard to find, and how Bliley's innovative pricing approach will make your procurement process so much easier.

The most common types of crystal oscillators in the world of electrical & RF engineering include OCXO, VCXO, clock oscillators, and (you guessed it) TCXO oscillators. If you're reading this post, you must want to learn more about temperature compensated crystal oscillators (TCXO). Let's dive in and learn the basics of TCXO oscillators.

Introducing the TCXO (Temperature Compensated Crystal Oscillator)

The TCXO, Temperature Compensated Crystal Oscillator (Xtal oscillator), is a form of crystal oscillator used where a precision frequency source is required within a small space and at a reasonable cost.

By applying temperature compensation within the quartz crystal oscillator module, it is possible to considerably improve on the basic performance of the crystal.

In view of their usefulness, a wide range is available from many suppliers in a whole variety of packages and mounts (surface, through-hole). Some TCXOs are compatible with the dual in line format used for many through hole mounted integrated circuits.
