TCXO / VCTCXO photo - International Crystal ManufacturingTCXOs / VCTCXOs

International Crystal Manufacturing (ICM) carries a narrow line of TCXOs / VCTCXOs manufactured to ICM specifications by our affiliates.

A TCXO is a temperature compensated crystal oscillator. Compensation components have been added to enhance the temperature stability of the basic oscillator to improve performance in more critical applications.

A VCTCXO is a Voltage Controlled Temperature Compensated Oscillator.

TXCO / VCTCXO product types

ICM offers two major categories of TCXOs / VCTCXOs:

  • Thru hole TCXOs / VCTCXOs - leaded holder typically manually installed used where size is not a critical issue and automated production is not necessary.

  • Surface mount TCXOs / VCTCXOs - leadless components designed for pick and place or automatated production and used where size is a critical issue.



ICM TCXOs and VCTCXOs typically have frequency ranges from 9.6 MHz to 20 MHz.

If your application requires frequencies outside the above range for your TCXO or VCTCXO applications, please contact our engineers at 1-800-725-1426.

Typical applications

TCXOs are used in telecom timing modules, wireless systems reference oscillators (Microwave, etc.), precision instruments, and other frequency sensitive applications.

VCTCXOs are often used for frequency control in tactical radios, telecom timing modules, wireless systems, phase lock loop applications, and reference oscillators.


Features and benefits

  • ISO 9001:2008 certified ensures ICM customers always receive high quality reducing costly returns and reinspection while keeping production lines running as scheduled.

  • All ICM custom manufactured high end precison crystals are 100% inspected on state of the art computer-controlled test equipment, not lot inspected, to meet specifications before shipment ensuring customers receive product that functions to required specifications every time ensuring no production downtime, minimizing rework, and eliminating customer returns due to component failure of ICM products.

  • U.S.-based complete automated, state of the art, manufacturing facility providing faster request response, better customer service, and faster deliveries.

  • Total control of all precision crystal production processes on custom-produced products ensuring deliveries meet needed product specifications.

  • Family owned, on-site management, ensures customers can speak directly to the ultimate decision maker resolving problems or providing solutions quickly.

  • No minimum order ensures customers can get exactly the quantities of product they need reducing receiving, inspection, and testing costs while also reducing inventory management costs.

  • On-shore automated manufacturing of precision crystals ensures quick deliveries reducing inventory-carrying costs.

  • Ability to produce prototypes to orders of tens of thousands of units ensuring customers get exactly what they want and reducing the number of needed suppliers to one.

  • Have crystal engineers on staff to provide design, prototyping, and pre-production support eliminating the need for multiple vendors and associated paperwork costs by having a single source for specialized precision crystal expertise.
