3 Reasons to Order OCXOs in Large Batches

Posted by Bliley Technologies on Jan 16, 2023 8:00:00 AM

 

Virtually all electronic components benefit from mass production. As it turns out, it’s harder to benefit from buying a few parts compared to buying many. This is true for the production and ordering of Oven-Controlled Crystal Oscillators (OCXOs). There are several important advantages to buying these in bulk instead of in small quantities, including lower setup costs, shorter lead times, and reduced impact of supply chain issues.

Oscillator Aging: How Long Is an OCXO’s Shelf Life?

Posted by Bliley Technologies on Dec 19, 2022 8:00:00 AM

 

We’re often asked if it’s wise to purchase crystal oscillators in large batches, especially when commodity managers are aware all the oscillators might not be used right away. 

By nature, crystal oscillators are made of natural quartz material, which gives them a very long shelf life. In this article, we’ll take a look at why that is and how the stability of crystal oscillators gives them an indefinite shelf life.

OCXO Lead Times Explained: How Aging Factors into OCXO Development

Posted by Bliley Technologies on Dec 5, 2022 8:00:00 AM

 

“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.

Crystal Aging and a Counter-Intuitive Tip to Improve System Performance

Posted by Bliley Technologies on Nov 23, 2022 9:00:00 AM
One of the most common configurations of a frequency control device or oscillator is one where the voltage is adjusted to maintain a frequency lock within the system. In these types of systems, frequency error related to the oscillator can have a detrimental effect on system performance. In the most extreme cases, it can actually result in complete system failure when a good frequency lock cannot be maintained.

The Secret to Low Phase Noise in Crystal Oscillator Circuits

Posted by Rob Rutkowski on Aug 26, 2021 9:06:00 AM

Quartz crystal oscillators are the high and mighty option for low phase noise and added frequency stability in circuit design. Yes, simple oscillators like those made with resistor-capacitor (RC) or inductor-capacitor (IC) resonators are fine for some circuits. But if you're dealing with higher performance applications in aerospace, military, and space industries... you're going to want a higher performance crystal oscillator that can maintain low phase noise & strong stability. Otherwise, you'll risk deviating from the very specific (and many times critical) center frequency selected for your design.

Crystal Oscillators: The Beginners Guide (OCXO, TCXO, VCXO, Clocks)

Posted by Rob Rutkowski on Aug 9, 2021 7:03:00 AM

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 the almost endless application uses. From satellite communications in space, to military & defense, to telecom and more... there's so many different needs for crystal oscillators. 

In this post we'll cover the most common types of crystal oscillator which include

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

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.

Top 8 Cost Drivers of Crystal Oscillators (How to Save on Costs)

Posted by Rob Rutkowski on Jul 13, 2021 8:15:00 AM

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.

Note: Oscillator pricing is very dependent on your specific needs and application. Be sure to contact us for specific information and pricing based on your needs.

Buy OCXOs - Immediate Oscillator Pricing for Design Engineers

Posted by Rob Rutkowski on Oct 6, 2020 8:30:00 AM

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.

Also, be sure to check out our OCXO immediate pricing guide at the end of this post!
