Oscillators have been widely used in many modern day communications systems. They are often used for signal reproduction, modulation, and generation, among other things, making them critical components of any system. Among the many oscillator models available today, one of the most popular is the ASTMUPCV-33-7.3728MHZ-LY-E-T. This article will discuss the application field and working principles of this oscillator.

Application Field

The ASTMUPCV-33-7.3728MHZ-LY-E-T is an inductor-capacitor type variable oscillator that can be widely used in satellite, wireless and fiber optic communication systems. It is specifically designed for cable television applications, specifically for providing the ultrosonic frequency reference to the video encoders and cable modems. The oscillator\'s frequency stability and low phase noise make it ideal for applications that require ultra-low noise output.

The ASTMUPCV-33-7.3728MHZ-LY-E-T also offers advanced temperature and supply voltage compensation, allowing for stable operation in a wide range of environmental conditions. The oscillator is reliable, digital adjustable and configurable for a wide range of applications, making it a versatile tool for system designers.

Working Principle

The ASTMUPCV-33-7.3728MHZ-LY-E-T relies on an inductor-capacitor (LC) tank circuit to generate an oscillating frequency. The LC tank circuit uses an inductor and a capacitor connected in series to create an ongoing oscillating frequency as electrons flow back and forth between the two components. By applying a voltage to the components, a signal is generated that oscillates at the desired frequency.

The ASTMUPCV-33-7.3728MHZ-LY-E-T is designed to maintain its frequency stability despite environmental and load variations. This is accomplished by using a voltage-controlled oscillator (VCO) as the core of its circuitry. The VCO is capable of responding to the external noise and stability sources, allowing the oscillator to maintain the desired frequency. Furthermore, an on-chip temperature-compensated crystal oscillator (TCXO) is used to maintain temperature stability as well.

The oscillator\'s output can be adjusted and configured using external components and the on-chip digital logic. An external resistor can be connected to the oscillator\'s input to adjust its pull-in range, and an external capacitance can be connected between the output and ground to maintain the output stability. Furthermore, the on-chip digital logic can be used to control the frequency, allowing the user to adjust the frequency to suit specific applications.

The ASTMUPCV-33-7.3728MHZ-LY-E-T is an example of an inductor-capacitor type variable oscillator that offers advanced performance and wide applications in satellite, wireless and fiber optic communication systems. Its high frequency stability and low noise output make it an ideal choice for system designers.
