Ask the Engineer: how temperature-sensitive are quartz crystals?
Nowadays, Christmas without quartz crystals is unimaginable! Why? Even the modern time switches for outdoor lighting need a quartz to have an accurate time base. Also, a lot of our gifts are based on state-of-the-art electronics. Cell phones, smartwatches, PCs – they all need highly accurate frequency giving components to communicate with each other. Without

What is the similarity between a quartz blank and a pillow?
Do you already know the similarity between a quartz blank and a pillow? Exactly! Both have the same shape. The so-called “bevelling” or “contouring” in the production process of quartz blanks results in the characteristic lens shape of quartz blanks. “This procedure is mainly used for ‘thicker’ blanks, which are in the low frequency range,

Why does a quartz crystal have to be hermetically sealed?
What you always wanted to know about quartz crystals, but didn’t dare ask until now … – Why does a quartz crystal have to be hermetically sealed? At the end of the complex production of a quartz, or rather the small quartz disc, the quartz blank, it has to be mounted in a housing that

TCXO: How it works and why
A TCXO is a temperature-compensated crystal oscillator that is used whenever particularly high stability within a variant temperature environment is required, i.e. when the frequency deviation of the oscillator must be minimal over its entire operating temperature range. Oscillators using AT quartz crystal plates, so called “blanks”, are the most economical solution to create a

The Strengths of 32.768 kHz Oscillators
The boom of quartz watches in the 70s has shown: When it comes to precise time recording, there is nothing better than quartz crystals! This is no different today. Frequency control products with the characteristic frequency of 32.768 kHz can be found in almost all applications with integrated time measurement, e.g. laptops, mobile phones or

Oscillator Circuits: The Most Important Test Procedures
Many engineers do not spend much thought on quartz crystals while designing their oscillator circuit. For them, it is a standard feature that will work anyway. In fact, it’s not that simple. The oscillator circuit sets the heartbeat of the application and requires a careful matching between the quartz crystal and its other components. Otherwise

Customer Success Story: Deeper’s Smart Fish Finder
Fishing is one of the most relaxed hobbies you can imagine. Just cast out your line and hope a fish will take the hook. Sometimes however, the angler’s patience is not rewarded and he has to return home without having caught anything. If you want to avoid this disappointment and don’t want to rely on

How Does an Overtone Quartz Crystal Work?
A fast and smooth data transmission is critical in today’s world. Network and server systems are designed to process and forward information at lightning fast speeds. To achieve this, many of these applications depend on frequencies in the three-digit megahertz (MHz) range. Such high frequencies cannot be generated with an AT-crystal in the fundamental tone.

It’s All about the Angle – The AT-Cut for Quartz Crystals
Whether medical technology, telecommunications or consumer electronics, quartz crystals have established themselves as a precise frequency generator in all industries. When energized, the thin quartz disc oscillates at a steady rate and thus determines the heartbeat of the application. While this sounds simple, the matter is quite complex because quartz blanks are not all the
