TCXO Oscillators

A TCXO is a high-precision crystal oscillator that utilizes a temperature-load compensation circuit to maintain an approximately flat frequency-temperature characteristic. It achieves frequency stability within 1 ppm while being designed in the smallest possible form factors. HCI offers both voltage-controlled (VC-TCXO) and non-voltage-controlled versions, with various sizes, frequencies, stabilities, and output types available. These oscillators are widely used in communications, navigation, mobile terminals, precision instruments, and military applications.

Working Principle of Industrial Temperature TCXOs 2520

 

TCXO monitors changes in ambient temperature through a built-in temperature sensor and adjusts its output frequency in real time to offset the impact of temperature fluctuations on the crystal oscillator. Compared with ordinary crystal oscillators, temperature compensated crystal oscillator not only provides higher frequency stability, but also can maintain accurate frequency output in environments with great temperature changes. This technology makes it an ideal choice in many applications that require high-precision time synchronization.

 

How to choose Industrial Temperature TCXOs 2520

Frequency stability: Choose the frequency stability that meets your needs. Generally speaking, high-stability TCXO are more suitable for precision measurement and high-end applications, but their prices are higher.

 

Temperature range: Select the appropriate operating temperature range according to the use environment. Ordinary products can withstand temperature changes from -40°C to +85°C, while higher-end products can operate in extreme environments from -55°C to +125°C.

Power requirements

For battery-powered devices, low-power TCXOs can effectively extend battery life.

Package size

Select a TCXO of the right size according to the space limitations of the device to ensure that it can be integrated with the existing system.Such as TCXO 1612, TCXO 3225.

Cost-effectiveness

Select cost-effective products according to the project budget, taking into account performance and cost.

 

Checking of Industrial Temperature TCXOs 2520

 

Temperature coefficient test

The most important thing to check when working with TCXO's is its temperature coefficient. It is done by exposing the device to the temperature range as specified in the data sheet and monitoring the frequency variation during the process. This technique is crucial because TCXOs are designed to provide frequency stability over a wider temperature range.

Output frequency and signal shape

The output frequency and waveform are other crucial checks in TCXO 2520. Connect an oscilloscope to the output to observe the output signal if one is in doubt or wants to make sure of the signal form. The oscillator parameters have to output a certain specific frequency, which, when it deviates from the standard frequency, must not deviate more than a certain stipulated limit. Any significant deviation or distortion in the signal can affect the overall performance of the oscillator circuit that is designed to receive the output.

Power Supply Voltage

Another important thing to check on TCXO 2520 is the power supply voltage. Ensure that only the required voltage is supplied to the TCXO because voltage deviation can cause frequency instability or worse, damage the device.

Load Capacitance Check

Each TCXO has a load capacitance specification, which means that it has to be matched with its corresponding load capacitance. Further, deviations from this value may lead to frequency shifts, thus giving resultant frequency instability. An oscilloscope is to be connected to the TCXO output to measure the load capacitance.
