TD-76.800MCD-T

Oscillators are valuable components for many electronic or electrical systems, where they generate electrical signals with a certain frequency, or simply control a repeating event for an extended period of time. TD-76.800MCD-T is a specific type of oscillator which is used to produce a stable frequency signal for an extended period of time. In this article, the application field and working principle of this specific oscillator shall be discussed.

TD-76.800MCD-T is a quartz crystal oscillator which is suitable for many applications, most prominently in telecommunication systems such as cordless and cellular phones, mobile satellite systems, and wireless LAN. The primary function of a quartz crystal oscillator lies in its incredibly stable output frequency, which is typically lower than 100MHz and can remain stable for thousands and thousands of hours without any need for adjustment. The TD-76.800MCD-T in particular has a frequency range that spans from 1MHz to 10MHz with the option of adjusting the frequency output from 300Hz to 800kHz.

Working Principle

TD-76.800MCD-T is based on the oscillatory property of a quartz crystal, known as the piezoelectric effect. When a voltage is applied across a quartz crystal, the crystal will undergo a small deformation due to the attractive force between the electrical field and the crystal\'s structure. This deformation will cause a change in the crystal\'s electrical properties which, in turn, changes the voltage applied to the crystal. Since this process of applying and dropping the voltage is done cyclically, the output frequency of the crystal is also cyclically varied.

The frequency range of the oscillator is adjusted using an LC (inductor 1-capacitor) circuit. By varying the rate at which the LC circuit charges and discharges, its natural resonance frequency can be changed. This LC circuit follows the output of the crystal to modulate its frequency. In the case of TD-76.800MCD-T, the frequency can be adjusted from 1MHz to 10MHz.

The TD-76.800MCD-T is a stable, reliable, and easily adjustable oscillator. Its wide range of application make it suitable for many kinds of electronic or electrical systems, especially telecommunication related ones as its output frequency is incredibly stable and reliable over time.
