In this blog, we'll review the basics of how an OCXO works, the terms you need to know, how to determine the turning point, and the differences between AT and SC crystal cuts.

Although GPS might perform well enough consumer usage, signal jamming or other disruptions present serious threats to military operations. Enter assured positioning, navigation, and timing (A-PNT), new technology that enhances traditional GPS timing. Assured PNT uses additional sources to augment GPS and prevent vulnerabilities. Its goal is to ensure that accurate positioning, navigation, and timing (PNT) is always available . In this blog, we'll review GPS, its flaws, and other PNT systems (like the GNSS) and give you an overview of how assured PNT technology uses other systems to improve effectiveness.

A crystal oscillator combined with electronic frequency control (EFC)! Of course, determining if EFC would be a good addition to your crystal oscillator circuit design (and if so, which method is best for you) comes down to your specific application and its requirements. There are four options to choose from when selecting an electronic frequency control method for your crystal oscillator: Pulse width modulation (PWM)low-pass filter (LPF) Reference RF signalphase locked loop (PLL) Voltage divide Digital-to-analog converter (DAC) In this post, we'll take a closer look at each option and their best applications.

The crystal blank is the resonating element of the oscillator that, when subjected to a voltage potential, will begin to vibrate and oscillate at its fundamental frequency. The way the crystal blank is manufactured can have a significant impact on the oscillator's performance. In this blog, we'll be discussing how the orientation of the quartz when the crystal blank is cut can affect how your oscillator performs.

Posted by Bliley Technologies on Oct 27, 2023 9:00:00 AM Tweet Why is it important to choose the right crystal oscillator output signal? The output signal types of crystal oscillators can provide different benefits and drawbacks depending on what you're trying to accomplish with your product. With that said, it's important to understand signal types to avoid as much attenuating and distorting of your clock signal as possible . You'll also want to be sure you're receiving more benefits than drawbacks from the signal to meet your specific design needs.

But in the real world, no crystal oscillator produces a 100% perfect signal. Even if the signal is very strong and clear, there will still be tiny, random fluctuations in its waveform. This phenomenon can be represented visually in the frequency domain as sidebands on either side of the carrier. These unwanted fluctuations are referred to as phase noise . In the blog, we'll explain why you need to measure phase noise, what the methods are for measuring it, and Read More 0 Comments Click here to read/write comments Topics: crystal oscillators AT vs. SC-Cut Quartz Crystals: Is EFC Over-Specification Costing You? Posted by Rob Rutkowski on Oct 12, 2023 9:00:00 AM Tweet 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.

But a single perturbation can cause major problems in an application’s signal, including within GPS or missile systems. Imagine launching a missile and then losing control of its navigation. Or getting a very inaccurate GPS velocity reading of an aircraft. These (and many other problems) can be caused by a failure to spot activity dips in crystals. In this article, we'll help you understand what frequency perturbations are and how to prevent them from occurring in crystal oscillators.
