530EB000274DG Oscillators

Oscillators are electrical circuits capable of producing a repetitive, exact frequency output. They are used in numerous applications, ranging from digital watches and clocks to computer networks, radio transmitters and receivers, microwave frequency synthesisers, and mobile communication systems. The 530EB000274DG is a popular oscillator from Rakon, a New Zealand-based semiconductor and electronic components manufacturer. This article explains the application field of the 530EB000274DG and its working principle.

Applications

The 530EB000274DG is a low-phase noise rubidium oscillator, designed for use in precision frequency control applications. It is ideal for aerospace, military, and telecommunications applications requiring long cycle-to-cycle performance over a wide frequency range, such as temperature, shock, and vibration environments. The 530EB000274DG oscillator features excellent thermal and environmental performance, enabling reliable frequency control.The 530EB000274DG is highly suited for high-performance timekeeping and distribution applications. This includes satellite navigation in the Global Positioning System (GPS) as it can provide accurate timekeeping, phase-locked loops, frequency synthesizers, instrumentation, and miniature computers. It is also suitable for precision monitoring and measurement of seismic data.

Working Principle

The 530EB000274DG oscillator functions by using a rubidium reference-cell (Rb cell) to produce a stable frequency signal. The Rb cell functions as a frequency-stable cavity, filled with rubidium metal, which is an inert noble gas. The 530EB000274DG oscillator utilizes a surface acoustic wave (SAW) filter and a temperature-compensated crystal oscillator (TCXO) to ensure precision frequency control.The SAW filter is used to reduce noise signals coming from the environment, such as interference from radios, television signals, etc. The frequency stability and accuracy is maintained by using the low-drift characteristics of the Rb cell. The temperature-compensated crystal oscillator (TCXO) helps to further reduce drift by providing precise frequency temperature compensation.

Conclusion

The 530EB000274DG oscillator is a highly accurate and reliable oscillator for precision frequency control applications. It is ideal for a number of applications, such as satellite navigation in the Global Positioning System (GPS), instrumentation, miniature computers, phase-locked loops, frequency synthesizers, and precision monitoring and measurement of seismic data. The 530EB000274DG oscillator works by using a rubidium reference-cell (Rb cell) to produce a stable frequency signal, which is then filtered by a surface acoustic wave (SAW) filter and a temperature-compensated crystal oscillator (TCXO) to ensure precision frequency control.
