Crystals

Crystals are electronic components made up of two or more coupled networks or oscillators, with each network or oscillator electrically isolated from the others. The coupling between the networks or oscillators is provided through a crystal. Examples of crystals include the 7M-24.000MDHV-T, which is primarily used in oscillator circuits.

Application Field of the 7M-24.000MHV-T

The 7M-24.000MHV-T is a high-frequency voltage controlled crystal oscillator (VCXO) that operates from a low-voltage DC supply (1.8-3.3V). It is mainly used in the following areas:

• Wireless communication systems.
• Small to mid size portable electronics.
• Consumer electronics.
• Telecommunication systems.

Working Principle of the 7M-24.000MHV-T

The 7M-24.000MHV-T VCXO is based on a quartz crystal element, which will change its resonant frequency according to the applied voltage. The crystal element is surrounded by an oscillator circuit, which will sense the change in resonant frequency and adjust the frequency of the oscillator accordingly. The 7M-24.000MHV-T crystal operates at 24MHz, and its frequency can be varied by +-25ppm over its rated frequency.

The 7M-24.000MHV-T VCXO consists of two sections, the oscillator and the crystal. The oscillator consists of an amplifier, charge pump, and a loop filter that are required to stabilize the frequency of the oscillator. The crystal is a quartz element, which is responsible for generating the basic frequency of the oscillator. The frequency of the oscillator is determined by the characteristics of the crystal.

The voltage applied to the crystal is used to alter its resonant frequency. When the voltage is in excess of the rated voltage, the crystal will tend to generate a frequency greater than the basic frequency. Conversely, when the voltage is lower than the rated voltage, the crystal will generate a frequency lower than the basic frequency. This frequency variation is used to adjust the frequency of the oscillator to the exact frequency of the crystal.

The 7M-24.000MHV-T VCXO is built with a conditioner, which allows for the adjustment of the supply voltage. The conditioner uses a closed loop control to keep the frequency from drifting, and this design results in a highly efficient circuit operation. In addition, the 7M-24.000MHV-T VCXO is designed with a high-impedance input, which allows for the use of a wide range of control voltages.

Conclusion

The 7M-24.000MHV-T crystal is a versatile and robust oscillator that can be used in a wide range of applications. The voltage controlled crystal element allows for precise and consistent frequency control. The highly efficient circuit design and high-impedance input make the 7M-24.000MHV-T convenient and cost effective.
