Oscillators

Oscillators are electronic circuits, which are designed to generate a repeating signal. They are widely used in audio, radio, and computing devices. Most oscillators are used to generate a periodic, continuous signal. The output signal can be a sine wave, a square wave, or a sawtooth wave, depending on the application. They are used to control the frequency of an oscillator circuit, provide a steady signal, or even drive the frequency of another circuit.

CMX309HBC53.125MTR application field and working principle

The CMX309HBC53.125MTR is a temperature compensated oscillator (TCXO) suitable for use in cellular communications, industrial automation, telemetry, and global positioning systems (GPS) applications. The operating temperature range of this oscillator is from -40°C to +85°C and it operates with a voltage of 3.3V and frequency of 53.125 MHz. This oscillator operates on the principle of sidebands, which create multi-frequency signals at distinctively separated frequencies from an initial signal.

The TCXO circuit consists of an oscillator, an amplifier, a temperature sensor, and a capacitive divider network. The oscillator is driven by an amplifier which is in turn supplied with power from the 3.3V input. The oscillator is a sinusoidal waveform and is generated by a quartz crystal. A temperature sensor placed near the crystal senses the temperature and provides a feedback signal. This feedback signal is then used to adjust the capacitive divider network which tunes the oscillator frequency. This way, the frequency of the oscillator is kept stable, even in the presence of electrical or environmental disturbances.

The output of the oscillator is a signal with an extremely small sideband of frequency 53.125MHz. Due to its operating temperature range and frequency stability, the CMX309HBC53.125MTR is very well suited for applications in which precision is of the utmost importance. These applications include cell phone base stations, telemetry and command systems, GPS receivers, high precision navigation systems, and other industrial automation applications.

The frequency stability of the CMX309HBC53.125MTR makes it an extremely reliable component for use in a variety of time- and frequency-sensitive applications.
