Inside Frequency Control

The TCXO Oscillator: 5 Elements of Temperature Compensated Oscillators

Posted by Bliley Technologies on Jun 23, 2020 8:15:00 AM

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.

The Ultimate Guide to Atomic Clocks in Space

Posted by Rob Rutkowski on Jul 9, 2019 11:20:13 AM

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. Atomic clocks can maintain very precise timing, making them a great timing solution for GPS and other LEO satellites.

7 Incredibly Effective Ways to Prevent Pressure Transducer Problems

Posted by Rob Rutkowski on Feb 19, 2018 8:28:00 AM

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 not only can cause frustration and wasted time, but 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 7 pressure transducer troubleshooting methods to keep your transducers & sensors working great!
