Oscillators are an important element in many devices since their purpose is to create a stable amplitude oscillation. The ASEMB-25.000MHZ-LC-T oscillator is one of the oscillators available in the market for applications that require high frequency, good stability and precise wave shape. This oscillator is considered one of the most innovative, reliable and successful oscillators in the market thanks to its superior performance characteristics.

Application Field

ASEMB-25.000MHZ-LC-T oscillator offers an array of versatile applications areas for various electronic applications. Examples include: local oscillator signal in communication systems, electronic instruments, test and measurement equipment, GPS systems, point-to-point radio links, baseband non-transmitting frequency or clock signals in electronic circuits. Additionally, this oscillator is also suitable for any application that needs an exceptionally high frequency and precise wave shape.

Working Principle

The working principle of the ASEMB-25.000MHZ-LC-T oscillator is based on a quartz crystal as a resonator and an electrical circuit designed to receive, filter and amplify signals for generation of oscillations with precise wave shape and frequency. The oscillator works in open-loop configuration where the output is not regulated for incoming signals. The quartz crystal is housed in a cavity and when a voltage is applied to its plates, it vibrates according to its “natural” frequency. Feedback from the oscillator output to its input is used to control the frequency of oscillation. The frequency is also affected by the “load capacitance” of the circuit.

The quartz crystal has several advantages when compared to other types of resonators, like the mechanical resonators (e.g. pendulum) which require a continuous supply of energy to keep oscillations, suffer environmental disturbance, and are affected by mechanical disturbances. The quartz oscillator requires no external power, is robust, and provides a reliable frequency output in a stable environment.

Performance Characteristics

The ASEMB-25.000MHZ-LC-T oscillator is capable of operating over a wide temperature range of -20°C to +85°C. While oscillation frequencies remain relatively stable over the entire temperature range, the maximum frequency variation is 0.5ppm (parts per million) over the temperature range. In addition, the ASEMB-25.000MHZ-LC-T oscillator has a frequency-stability range of 0.08ppm, meaning that its accuracy is within 0.08ppm over its working temperature range. Furthermore, the ASEMB-25.000MHZ-LC-T oscillator has a low power consumption of 25mA and can output up to 125 mW. It also has an extremely low phase noise of better than -91dBc/Hz.

Conclusion

The ASEMB-25.000MHZ-LC-T oscillator is an extremely reliable and precise oscillator which offers a wide temperature range of working environment. Its superior performance characteristics make it an excellent choice for applications that require frequencies of around 25MHz, superior accuracy and precise wave shape. In addition to the advantages of quartz crystal resonators, the ASEMB-25.000MHZ-LC-T oscillator also has a low power consumption of 25mA and can output up to 125 mW making it a great choice for low power products.
