Oscillators

An oscillator is an electronic device that converts alternating current (AC) into pulses by “oscillating” or reversing direction at a certain frequency. They are used to generate an exact frequency for controlling the timing of digital devices, including microprocessors and communications systems. Oscillators include quartz crystal oscillators, voltage controlled oscillators, phase-locked loop oscillators, and MEMS oscillators.

The CMX309FBC16.000M-UT oscillator is a frequency control device that uses a quartz crystal oscillator housed in a small ceramic package. The quartz crystal produces a constant frequency that is determined by the size of the oscillator and is held at a steady rate by a feedback loop. In addition to frequency control, the oscillator can also be used for phase control.

Application Field

CMX309FBC16.000M-UT oscillators are primarily used as frequency and phase control devices in high speed digital applications. They can be used to transmit and receive data in communications systems, including cellular, Wi-Fi, Bluetooth, and satellite networks. In addition, they are also used in microprocessor-controlled devices, such as smartphones, computers, and medical equipment, as well as in consumer electronics, ranging from automotive infotainment systems to DVD players.

Working Principle

The CMX309FBC16.000M-UT oscillator is based on a quartz crystal oscillator circuit. A quartz crystal provides an accurate frequency reference, which is maintained by a feedback loop at a constant rate. When a signal is applied to the oscillator, the crystal vibration frequency is used to generate a corresponding sine wave signal. The oscillator is designed to ensure that the signal remains constant regardless of environmental factors or changes in electrical parameters.

The feedback loop within the oscillator provides stability to ensure that the frequency does not deviate from the set point. Synchronous rectification is used to reject any noise from the input signal, and the output is then buffered and filtered to ensure that it is clean and free of any jitter or distortion. Lastly, the output is amplified to match the required signal level.

The CMX309FBC16.000M-UT oscillator has a wide operating temperature range of -40°C to +85°C. It is also available with different output configurations to meet different application requirements. The package size is 7.0mm x 5.0mm, making it suitable for applications where space is limited.

CMX309FBC16.000M-UT oscillators are widely used in many different applications due to their high accuracy and stability. These oscillators are ideal for use in microprocessor-controlled devices as well as in automotive and communications applications.
