Next Generation Chip Scale Atomic Clock

Next Generation Chip Scale Atomic Clock

Posted: 10th December 2020
With the world moving towards global synchronous communication and data distribution, and high accuracy for autonomous applications, the need for greater timing accuracy is at the forefront of design engineers’ minds. One should not be forced to compromise application design parameters to account for the requirements of the on-board oscillator. This blog provides an… Read More

Bye bye to plastic packages

Bye bye to plastic packages

Posted: 19th October 2020
During the 1990s, a number of high profile global manufacturers of frequency products developed plastic packaged crystals and oscillators. They purchased a lower-cost alternative to what were back then more expensive, the ceramic-and metal-based packages. Consequently, large manufacturers dominated the marketplace and took many design-wins with these plastic devices over… Read More

How a few pico farads can ruin your timing accuracy

Figure 1  Trim sensitivity of a quartz crystal depending on the load capacitance

Posted: 1st September 2020
Quartz crystals are widely used in electronic applications because of their accurate frequency. Thanks to IoT, 5G and Industry 4.0, the demand for highly precise clock frequencies is increasing dramatically. However, by making a few mistakes during the design-in process the entire frequency accuracy of the quartz crystal can be ruined. This blog will focus on the… Read More

Myths around load capacitance – how to choose the right capacitors

Figure 1: Pierce Oscillator Circuit

Posted: 3rd August 2020
The load capacitance in the oscillation circuit is one of the most important values for guaranteeing the precision of a quartz crystal. Nevertheless, at the same time it is one of the most common causes of error during the design of an oscillation circuit. There are a number of misconceptions about load capacitance, which we want to clarify today. In addition to that, we… Read More
