TCXOs (Temperature compensated crystal oscillators)

Temperature compensated crystal oscillators typically employ a thermistor network to generate a correction voltage which reduces the frequency variation over temperature. TCXOs are preferred to oven oscillators in low power applications and when a warm-up period is not acceptable. The only warm-up time is the time required for the components to reach thermal equilibrium and the total current consumption can be very low - often determined by the output signal power requirements.

Our database is frequently updated with the latest brands and types of JITOs that enter the global market. For this we established a network of most reliable and known TCXOs manufacturers, suppliers and distributors. Good businesses happen through planning, cemented trust and a good corporate network.

Various factors lead engineers to design better and advanced product designs, these factors can very critical in determining the overall functionality of the device. One of the problems pointed out by engineers while testing their prototype was frequency variations over temperature; thus the idea for developing Temperature compensated crystal oscillators started taking shape. We have collected most famous types of JITOs available in the market onto a comprehensive database consisting of online catalogs of JITOs available online.

To multiply your business possibilities, you will have to develop strategies and erect pillars of trust with your clients; and we pledge to provide you with the resource to accomplish all these i.e. NETWORK.

Temperature Controlled Crystal Oscillators (TCXOs)
Temperature Controlled Crystal Oscillators (TCXOs) are used in portable telephones, cellular phones, communications equipment, cellular radios, and in aerospace and two-way radio communications.

Since they are available in low voltage, TCXOs are ideal for use in hand held, battery powered communications devices. These oscillators correct the output frequency against the effects of temperature. Temperature compensation is usually effected by a temperature-sensing device that regulates a variable capacitor, with the result that at any temperature within the design range of the oscillator, the output frequency remains nearly constant.
