Oscillators

This article is about the application field and working principle of 590AC135M000DG oscillator.
Oscillators are electronic circuits that generate repetitive signals in a particular frequency range. The main application of oscillators is to act as timing references for radio transmission, telecoms, computers, automated measurement and monitoring systems.The 590AC135M000DG oscillator is used for frequency synthesis of high accuracy and phase noise. It is an OCXO (Oven Controlled Crystal Oscillator) with a low profile. It has a frequency range from 10 MHz to 125 MHz with an operating temperature range of −40 to +85°C. It operates between −5.2 to +9 V DC with 0.25 V DC tolerance.

Working Principle of the 590AC135M000DG Oscillator

The 590AC135M000DG operates on the principal of a quartz crystal. When a quartz crystal is cut to a particular dimensions and then electricity is applied to it, a predictable mechanical vibrational frequency will be generated. When the crystal is added into a circuit it will continue to maintain this frequency over a broad range of temperature and humidity by using an active oscillator circuit.The 590AC135M000DG has a very accurate phase noise due to its resonator in the form of a quartz crystal. The crystal is heated up to the desired temperature using an oven, thus providing stable frequency operation over a wide temperature range. In addition, the oscillator includes a PLL (phase locked loop) circuit that reduces phase shift thus providing very accurate phase noise.

Conclusion

The 590AC135M000DG oscillator is a high accuracy and low profile OCXO that is suitable for use in applications such as frequency synthesis. It operates on the principle of a quartz crystal, which is heated up to the desired temperature in an oven. The oscillator also includes a PLL (phase locked loop) circuit that reduces phase shift and thus offers very accurate phase noise.
