Temperature Compensated Crystal Oscillators (TCXOs)

A temperature compensated crystal oscillator (TCXO) is a type of crystal oscillator that is designed to maintain a stable frequency over a wide temperature range. It is a type of crystal oscillator that uses a temperature sensor and a temperature-compensating circuit to maintain a constant oscillation frequency despite changes in temperature. TCXOs are commonly used in applications where frequency stability is critical, such as in GPS receivers, cellular phones, and test and measurement equipment. They are known for their high accuracy, low phase noise, and low power consumption.
