An oscillator is a device or system that generates a periodic signal, such as sine waves, square waves, or sawtooth waves. EG-2121CA 125.0000M-LHRAB is an example of a high-performance, low-power oscillator which can provide high accuracy and stability, low power consumption, and good frequency-temperature stability characteristics. This oscillator can be used in a variety of applications, such as automotive and consumer electronics.

Design

The EG-2121CA 125.0000M-LHRAB is a miniature oscillator that incorporates a piezoelectric resonator in a hermetically sealed package. The piezoelectric resonator is a thin, quartz crystal which acts as a vibrating element when stimulated by an AC or DC signal. Its frequency can be adjusted by controlling the amplitude and/or shape of the AC signal applied to it. The resonator is enclosed in the device’s sealed ceramic package in order to protect it from external interference, mechanical damage, and environmental conditions that may affect its performance.

Working Principle

The EG-2121CA 125.0000M-LHRAB works by using a feedback loop to maintain the output frequency. The oscillator works by harvesting energy from the resonator and using it to provide a stable output frequency. This oscillator incorporates a hybrid circuit that uses both the basic circuit topologies of a low-power resonator and a higher power Pierce oscillator. This combination creates an efficient and reliable source for obtaining a stable frequency.

The EG-2121CA 125.0000M-LHRAB first starts its cycle by generating a negative voltage. This voltage is then feedbacked to the oscillator\'s amplifier stages, which in turn produces an output signal that is passed through an output amplifier before being sent to the device’s output terminals. As the signal travels through the oscillator’s components, its frequency is stabilized by the negative voltage generated by the resonator.

Application Fields

The EG-2121CA 125.0000M-LHRAB can be used in many different application fields, such as mobile communication, automotive electronics, consumer audio, industrial control, aerospace navigation, medical devices, and automatic testing. The device is also suitable for applications that require high performance but low power consumption. Typical applications include frequency control for radio receivers, cell phone base stations, Global Positioning System (GPS) receivers, satellite navigation systems, wireless clocks and watches, and personal video recorders.

Conclusion

The EG-2121CA 125.0000M-LHRAB is an excellent oscillator for many different application fields. It works by using a feedback loop to maintain the output frequency, and incorporates both a low-power resonator and higher power Pierce oscillator that are very efficient and reliable. This device offers high accuracy and stability, low power consumption, and good frequency-temperature stability characteristics, making it a great choice for a wide variety of applications.
