Introduction

Resonators are component devices used to help attenuate unwanted noise, vibration, or interference in a system. The CSTCE16M0V51-R0, formerly known as H0V51R, is a robust ceramic surface mount resonator with a capacitance tuning circuit. It has excellent stability and is widely used for communication applications for providing less than 1 ppm frequency drift over temperature. This article will discuss the application field and working principle of the CSTCE16M0V51-R0.

Application Field

The CSTCE16M0V51-R0 provides temperature stability over a wide range, making it a widely used component and suitable for a variety of applications. It is capable of providing an oscillator frequency of 155.5 to 6250 MHz. The device is also compatible with a variety of other components, such as filters and mixers, and is suitable for use in demodulator and mixer modules. Additionally, it has a high rejection rate of up to 75 dBc/Hz which makes it suitable for use in wireless communication applications requiring high reliability and performance.The CSTCE16M0V51-R0 resonator is typically used in applications such as frequency-hopping, spread-spectrum communication, global positioning system receivers, Wi-Fi and Bluetooth applications, frequency synthesizers, and AM/FM radio tuners. It can also be used for oscillators requiring highly stable oscillation frequencies for various communication systems.

Working Principle

The CSTCE16M0V51-R0 resonator is based on a capacitance-controlled resonator (CCR) oscillator principle. The basic structure consists of a capacitor and an inductor, connected in parallel, and enclosed in a ceramic package. The resonance frequency is determined by the inductance and capacitance, and is not affected by temperature.The device has a built-in temperature compensation circuit that allows the oscillator to maintain a stable frequency over temperature. This is accomplished by a feedback capacitor which varies with temperature, and a thermistor connected to the feedback connection. The thermistor senses the temperature and adjusts the feedback capacitor accordingly, allowing the device to maintain a constant frequency as the temperature changes.

Conclusion

The CSTCE16M0V51-R0 ceramic-package resonator is an excellent choice for a variety of applications requiring the stability of a CCR oscillator. It has a wide range of operating frequencies and is compatible with various components, making it suitable for use in many communication systems. Furthermore, its temperature compensation circuit allows the oscillator to maintain its frequency stability even when confronted with temperature changes.
