Oscillators: 656L66935C3T Application Field and Working Principle

An oscillator is an electronic circuit that produces an output signal periodically. Typically, the output, or output signal, is at the frequency of the input signal. Oscillators are used in many different types of application areas, from radio-frequency (RF) circuits and audio applications, to computer clock signals and control system timing. The 656L66935C3T is an oscillator, and it is used primarily in aircraft and automotive applications, and for frequency tracking communications systems.

The 656L66935C3T oscillator is a low-noise, voltage-controlled oscillator (VCO). It offers several features and benefits that make it ideal for its application areas. These include the following:

• Wide operating range – accepts inputs from 8.3 Mbps to 47 Mbps
• High frequency agility and stability – up to 3 GHz when interfaced with other devices
• Low Noise figure, typically 0.2 dBc/Hz
• Low power dissipation – typically 2.3 mW

The 656L66935C3T requires a 9V supply voltage and uses an active voltage-controlled crystal (VCX) as its core material. In addition, it relies on some external components, such as resistors and capacitors, to tune its frequency. These external components create feedback loops in the circuit, which allow the oscillator to rapidly respond to changes in the operating environment.

Just like any other oscillator, the 656L66935C3T produces an output signal at a certain frequency. This frequency is referred to as its ‘free running frequency’, as it only changes when the external components are adjusted. The accuracy of the free running frequency mainly depends on the quality of the external components used to tune the oscillator.

The primary working principle behind the 656L66935C3T oscillator is the same as any other voltage-controlled oscillator. The key elements in a VCO are the feedback loop and the voltage control elements. In the case of the 656L66935C3T, these are the external components (resistors and capacitors).

When a voltage is applied to the voltage control elements, they cause a change in the frequency of the output signal. This change is proportional to the voltage applied, and this is what makes the 656L66935C3T an ideal choice for tracking communications systems.

The 656L66935C3T is an excellent choice for aircraft and automotive applications, frequency tracking communications systems, and other applications that require rapid response and reliable performance. Its low-noise figure, high frequency agility and stability, and low power dissipation make it a reliable and efficient choice for any application.
