Oscillators are devices or systems which generate a signal with periodic or quasi-periodic oscillations. The signal thus produced is known as an oscillator signal, and is an important component in many engineering systems. This article discusses the application field and working principle of 353LB5C74AR Oscillator, a PWM frequency stepping oscillator manufactured by LongBeach Manufacturing Company.

The 353LB5C74AR Oscillator is a 14-bit frequency shift system with the large tuning range of 32 kHz to 4 MHz. It features a low-jitter, synthetic crystal oscillator with a jitter frequency of less than 5 MHz. The oscillator is built with an adaptive-compensation sensor which provides the steering for frequency-shift neutralization. The differential and single-ended PWM outputs are routed to a variable current source, resulting in a sinusoidal output signal. This output can be fed back to the crystal oscillator for improved phase noise performance. The oscillator also features a programmable user-programmable frequency-shift neutralization system, providing maximum flexibility in frequency control.

The 353LB5C74AR Oscillator is an ideal choice for applications requiring frequency domain linearization. It exhibits an excellent linearization performance in the frequency range of 32 kHz to 4 MHz, making it ideal for applications such as spread spectrum systems and RF range control. It is also ideal for use in tuning, amplification, modulation, digital frequency synthesis, crystal trimming, and related applications. The oscillator is available in both surface mount and through-hole packages.

The 353LB5C74AR Oscillator is designed to operate in a wide variety of conditions, providing reliable operation over a wide temperature range (-40°C to +85°C). It operates from a single 3.3V or 5V DC supply and features three separate power supplies: VIN1, VIN2, and VIN_EXT, for Wide Input Supply Range Operation. The oscillator provides low jitter, superior linearity and fast settling times, making it suitable for various frequency domain applications.

The basic working principle of the 353LB5C74AR Oscillator is based on the concept of frequency modulation. It works on the principle of generating a periodic waveform and performing a frequency shift operation for each frequency domain interval. The frequency shift is typically performed by using a variable resistor and then feeding back the shifted signal to the input. This creates a feedback loop, which is used to perform the frequency shift. As a result, a constant-amplitude waveform is generated with a varying frequency or phase.

In addition to frequency domain linearization, the 353LB5C74AR Oscillator can also be used for synchronization, modulation, and phase noise cancellation. It can be used for automotive applications, consumer electronics, medical, and industrial applications. The oscillator can be used in applications such as motor speed control, current-to-voltage conversion, signal processing, data-switched electronic receivers, and audio processing. It is also used for instrumentation, communication, and industrial automation.

The 353LB5C74AR Oscillator is a cost-effective and reliable choice for applications requiring frequency shifting and linearization. It features a wide operating temperature range and low power consumption, making it an ideal choice for many applications. The oscillator provides excellent frequency domain linearization, with superior sinusoidal output, making it a popular choice for many applications.
