Oscillators are devices that generate an electrical signal with a frequency that is generally controlled by an external signal, such as a crystal oscillator, voltage-controlled oscillator (VCO), and a temperature-compensated crystal oscillator (TCXO). The V7223T-074.1758M is a type of temperature-compensated oscillator (TCXO) and its application fields and working principle will be discussed in this article.

Application Fields

The V7223T-074.1758M TCXO is widely used in applications requiring highly stable frequency reference sources. It is suitable in communications protocols such Hot Sync, IrDA, Bluetooth, WiFi, and mobile communications timing circuits. It is also used for computing and consumer electronic products that require a stable frequency reference, such as laptops, computers, modems, cellular phones, and other mobile devices. Apart from that, the TCXO is also utilized as reference frequency sources in test & measurement, medical devices, industrial and military applications.

Working Principle

The working principle of the V7223T-074.1758M is based on Physik Instrumente\'s patent-pending mode-switch temperature control method. This is a temperature compensated voltage-controlled oscillator, which features a temperature-sensitive element in the frequency-control voltage path. This element can change its electrical characteristics based on the current operating temperature of the device, which allows the device to compensate for the temperature-dependent frequency shift and maintain its high stability performance.

The key component of the temp-compensated oscillator is the voltage-controlled oscillator (VCO). This is a device that controls the frequency of oscillation by modulating its control voltage. The control voltage is then phased locked by the onboard temperature controlled element, which tunes the oscillator\'s frequency at a variety of temperatures. This process allows the oscillator to maintain its high stability, even when subjected to operating temperature changes.

Conclusion

The V7223T-074.1758M is a temperature-compensated temperature-controlled oscillator which is suitable for a variety of applications. The onboard temperature controlled element allows the oscillator to maintain a stable frequency even when subjected to temperature changes. As a result, it is widely used in communications protocols, computing and consumer electronic products, test & measurement devices, medical devices, industrial, and military applications.
