A temperature-compensated crystal oscillator, or TCXO, is used when exceptionally high stability in a wide variety of temperature environments is required, i.e., when the oscillator’s frequency variation must be small across its whole operational temperature range.
The most cost-effective way to establish a steady and accurate reference frequency is to use oscillators that use AT quartz crystal plates, sometimes known as “blanks.” However, the precision of their frequency depends on the surrounding temperature. Accuracy is greatest at 25°C, which is the ideal temperature.
The frequency deviation will alter in accordance with a certain feature the farther the ambient temperature deviates from 25°C.polynomial function of third degree can be used to roughly represent the relationship between temperature and frequency deviation. You can also use a fifth degree function.
The Global Temperature Compensated Crystal Oscillators market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The term “TCXO” refers to a crystal oscillator that has a temperature-sensitive reactance circuit in its oscillation loop to correct the frequency-temperature characteristics of the crystal unit.
Epson printers are divided into two categories. One of these is a Direct-Type TCXO with an integrated temperature compensation circuit. The other type of TCXO indirectly controls oscillation frequency by including a temperature adjustment circuit separate from the oscillation loop.
Built-in quartz crystals allow Abracon TCXO Temperature Compensated Crystal Oscillators to provide temperature stability from 0.1ppm to 2ppm with frequencies up to 1.5GHz. In steady clock applications like Stratum III, GPS, RF, femtocells, and mobile communication, these TCXOs are perfect.
