What is a TCXO?

TCXO stands for Temperature Compensated Crystal Oscillator. This type of oscillator is used where the accuracy of a crystal oscillator on its own is not sufficient. 

The "Temperature Compensated" part simply means that the oscillator has a circuit that automatically adjust its frequency output to compensate for changes in temperature, over a wide temperature range. This helps make appliances for radio communications, GPS positioning and navigation possible in all conditions. 

Some of the most common applications that use TCXOs include:

  • GPS receivers
  • Wireless and cellular communications equipment
  • Test and measurement equipment
  • Scientific instruments
  • Aerospace and defence systems.

TCXOs are essentially a bridge between a XO and OCXO, which makes them often more expensive than a typical oscillator. A TCXO is much cheaper, smaller, and consumes much less power than an OCXO. The temperature compensation gives them a better accuracy than other oscillators and allows them to be used in applications where the accuracy is mandated. 

What is the difference between TCXO and VCXO?

A TCXO is similar in many ways to a VCXO but with one key difference:

A TCXO has an additional circuit that produces a tuning voltage that is dependent on the temperature of the circuit. This control voltage is designed to cancel out the temperature variation of the crystal and oscillator circuit frequency. For VCTCXOs the external tune voltage is added to the temperature correction voltage.
