Oscillators play a critical role in many electronic circuits and serve as timing references, frequency sources, noise sources, and ultimately, signal sources. The 520N10HT38M4000 is a monolithic oscillator that offers significant advantages in high frequency, low jitter, and low power operations. This oscillator uses an unconventional oscillator topology known as a “combination” oscillator, and offers significant improvements in output frequency stability, performance, and power requirements.

Application Field

The 520N10HT38M4000 is primarily used as a timing oscillator in a variety of applications including data communications, consumer electronics, and military/aerospace. Its combination oscillator topology gives it a wide range of frequency output options from 250KHz to several hundred MHz. This makes the 520N10HT38M4000 suitable for a variety of high-resolution, low jitter, and high speed designs. It is also capable of operating at very low power levels, which makes it ideal for battery-operated systems that require a low power consumption.

Beyond the frequency range and ultra-low power modes, the 520N10HT38M4000 is also used in applications that require high harmonic distortion tolerance. It is capable of rejecting 65 dB of harmonic distortion, and operates with no discernible performance penalties even when the input signal is heavily distorted. Thus, it is an excellent choice for applications that require high harmonic suppression.

Principle of Operation

A combination oscillator is based on two principles of operation. First, it operates under the principle of negative feedback, which means that the output signal is applied to the input as a reference signal, resulting in a stable, continuous wave output. Second, the oscillator combines an op-amp circuit with a voltage-controlled current source, which allows for a wide range of frequency variation with a minimum of distortion. In the 520N10HT38M4000, this combination results in a very high output accuracy and stability, even in unpredictable operating conditions.

The 520N10HT38M4000 operates on a 5 volt input supply, but can also accept a wide range of input voltages from 3.3 V to 8 V. This allows for easy integration and flexibility in a variety of diverse systems. Additionally, the oscillator is extremely power efficient, drawing an average of 1.2 mA of current from the input supply. This makes it an attractive solution for low power, low noise, high accuracy clock requirements.

Conclusion

The 520N10HT38M4000 oscillator is an excellent choice for any design that requires a high-resolution, low jitter, frequency source. Its combination oscillator topology results in superior stability and accuracy, and this oscillator is capable of operating in low power, low harmonic distortion, and different input voltage modes. Combined with its wide range of frequency outputs and acceptable harmonic distortion tolerance, the 520N10HT38M4000 is well suited to a wide variety of demanding applications.
