Crystals serve integral roles in a variety of electronic applications. One type of crystal is the TFE202V32K7680R which is used in a number of communication systems. This article will explain the application field and working principle of the TFE202V32K7680R crystal.
The TFE202V32K7680R crystal is typically used in radio frequency (RF) and microwave applications. Its low ESR and tight frequency stability characteristics make it well suited for applications such as broadband television tuners, satellite systems, modems, cellular phones, and other RF/microwave components. The TFE202V32K7680R crystal has a frequency range of 2 to 32kHz and a free-running frequency of 76.8MHz.
The TFE202V32K7680R crystal works by producing a constant signal frequency when voltage is applied to its terminals. A crystal oscillator typically consists of a tank circuit and the TFE202V32K7680R crystal. The tank circuit is made up of a capacitor and an inductor that are both tuned to the resonant frequency of the crystal. As the voltage applied to the crystal oscillator\'s circuit is increased, current flows through the inductor, causing the circuit to resonate. The resonating circuit energy is transferred to the crystal, causing it to vibrate at its natural frequency.
The frequency of the crystal oscillator is determined by the internal resonance structure of the crystal. Crystals are made up of a small piece of crystal lattice with electrodes that are connected to the leads of the crystal oscillator. As electricity passes through the crystal, it creates an electric field which causes the crystal lattice to vibrate at its resonant frequency. The frequency of the crystal depends on the size of the lattice and the material used to make it.
In order for the TFE202V32K7680R crystal to produce its stable output frequency, it needs to be mounted properly. The crystal must be mounted on a circuit board in a way that minimizes interference from external sources. This is important in order to ensure that its output frequency stays consistent over time.
In order to maximize the performance of the TFE202V32K7680R crystal, the manufacturer recommends that it be operated at 5 volts with a loading capacitance of 20 pF. The frequency of the crystal can be adjusted by changing the loading capacitance, however, this should only be done by an experienced technician.
The TFE202V32K7680R crystal is a low-cost solution for applications requiring high-precision frequency stability and low ESR values. Its frequency range and free-running frequency make it well suited for broadband television tuners, satellite systems, modems, cellular phones, and other RF/microwave components. It is important to properly mount the crystal in order to maximize its performance and ensure its long-term reliability.
