Oscillators

Oscillators are vital components in digital and analog circuitry. They provide a reliable time reference, helping ensure the steady delivery of power to components and processes. Additionally, they generate wave patterns for processing digital signals. Oscillators achieve this through electrical resonance — with the use of capacitors and inductors.

The 4MA155520Z4AACUGI8 oscillator (herein referred to as 4MA1555) is a component used to generate stable, accurate frequencies. It combines the Speed, Accurately, Low Power, and Frequency Stability performance features of oscillators for industrial, medical, and consumer applications, including communications, instrumentation, and automotive.

Application Field

The 4MA1555 provides a low power and small footprint, suitable for a variety of high-performance applications. It is capable of generating stable, accurate frequencies of 0.2MHz to 20MHz with high phase noise and wide frequency tolerance. The 4MA1555 is used in industrial, medical, and consumer applications including communications, instrumentation, and automotive. End users benefit from the low power consumption, frequency stability, and small form factor of the device.

In addition to its industrial applications, the 4MA1555 is suitable for consumer electronics, such as cell phones, video game consoles, and digital video decoders. Its low power consumption and ultra-low standby current help preserve battery life in low power applications. In medical applications, it is used in MRI, EEG, ECG, and EKG equipment to achieve precise and reliable frequency control.

Working Principle

The 4MA1555 oscillator works by setting up an electrical resonance between a capacitor and inductor. The oscillator circuit presents a current through an inductor and capacitor in series. The current creates an electrical field and causes the voltage across the capacitor to oscillate between positive and negative values. As the voltage across the capacitor changes, the current in the inductor also changes. This creates an oscillating current which generates a stable frequency.

The frequency of the oscillator can be adjusted by varying the capacitance and inductance of the components. The 4MA1555 is able to generate stable, accurate frequencies due to its high oscillator quality. It also provides for precise frequency adjustment turns ratio and its low jitter helps eliminate errors due to frequency instability.

Conclusion

The 4MA1555 is a highly versatile oscillator suitable for a wide range of applications. It combines the features of high speed, accurate frequency control, low power consumption, and frequency stability to produce reliable frequencies that are accurate and repeatable. It is particularly useful for consumer and medical applications due to its low power consumption and low jitter.
