Oscillators are electronic circuit components used to produce repetitive electronic signals such as square waves or sine waves. The CMX309FBC25.000M-UT oscillator is a high-performance crystal oscillator designed for precise timing applications. The CMX309FBC25.000M-UT operates at 25.000 MHz with excellent jitter performance at 0.75ps. This oscillator is available in a variety of standard packages, including the industrystandard 5x7mm SMD package.

The applications for the CMX309FBC25.000M-UT oscillator include, but are not limited to: GPS receivers, communication systems, aerospace, defense, space, satellite systems, medical systems, industrial systems, consumer products, and instrumentation. This versatile oscillator operates at a low power consumption of 0.7W, and it can withstand extreme temperatures from -40°C to 85°C.

The working principle of the CMX309FBC25.000M-UT oscillator is based on an LC oscillator circuit. The frequency of oscillation is determined by the resonant frequency of the LC circuit, which is directly proportional to the inductance and capacitance of the coil and capacitors that make up the LC circuit. In order to maintain a stable output frequency, the inductance and capacitance values should remain constant. To achieve this, the circuit employs a crystal that acts as a frequency reference. The crystal is designed to maintain a precise frequency whose output is then monitored by an oscillator circuit.

The oscillator circuit produces an AC signal whose frequency is monitored by the feedback mechanism of the oscillator. The signal is then divided by a divider circuit and compared to the reference frequency of the crystal, or resonator. The two signals are then compared in order to detect any discrepancies in frequency. If a discrepancy is detected, the oscillator will adjust itself in order to maintain the reference frequency. This process is referred to as “phase-locked loop” or PLL. By adjusting itself in this manner, the oscillator is able to maintain a constant output frequency.

The CMX309FBC25.000M-UT oscillator is intended for use in high-accuracy timing applications where precision and long-term stability are required. Its highly accurate output frequency of 25.000 MHz makes it ideal for use in GPS receivers, communication systems, satellite systems, medical systems, industrial systems, consumer products, and instrumentation.
