Programmable Oscillators: SG-8101CG-TJHPC Application Field and Working Principle

Programmable oscillators are used in a variety of applications, from data communication and networking to high-speed computing and engineering. They are also commonly used for timing, frequency shift keying (FSK), and frequency chirping applications. SG-8101CG-TJHPC is one of these types of oscillators. It is suitable for automotive, industrial controls, medical, and telecommunications applications. This article will discuss its application field and working principle.

Application Field

The oscillator contacts low ESR capacitors, making it suitable for high-speed circuits and tight frequency regulation requirements. It also has a 16-pin QFN package, which allows a small footprint and high-density performance. The device has a clock frequency of up to 1 GHz and can achieve very precise frequency and time constants with minimal circuit complexity.The main application fields for SG-8101CG-TJHPC include automotive, industrial control, medical, and telecommunications industries. In automotive applications, this device has been used in engine control, transmission control, and airbag systems. In industrial control, it has been used in motor control, factory automation, and process control systems. In medical applications, SG-8101CG-TJHPC has been used in medical device monitoring and safety systems. Lastly, this device is used in telecommunications applications, such as PON and xDSL systems.

Working Principle

SG-8101CG-TJHPC uses a programmable quartz crystal resonator as its clock source. A quartz crystal resonator is a mechanical structure that vibrates when a voltage is applied to it. The frequency of the vibration is determined by the size and shape of the quartz crystal, as well as the temperature of the environment the crystal is kept in.The SG-8101CG-TJHPC converts the voltage of the quartz crystal resonator into a digital signal using a high-precision frequency measuring circuit. The digital signal is then filtered with a low pass filter and processed by a digital signal processor before being output as a digital clock signal. The digital clock signal is divided into pulses of a specific frequency, with each pulse having a specific value. By programming the clock frequency of the device, the user can adjust the frequency of the clock signal and thus the length of each pulse.The device also provides an “overtemperature” shutdown feature. This feature prevents the device from operating at temperatures above a certain threshold, protecting the device and the circuitry connected to it from damage due to excessive temperature.

Conclusion

SG-8101CG-TJHPC is a highly reliable, programmable quartz crystal oscillator. It provides excellent performance in automotive, industrial control, medical, and telecommunications applications. Its 16-pin QFN package provides a small footprint and high-density performance. The device has a clock frequency of up to 1 GHz and can achieve very precise frequency and time constants with minimal circuit complexity. The high-precision frequency measuring circuit and low pass filter make the device very accurate and reliable. Lastly, the “overtemperature” shutdown feature protects the device and the circuitry connected to it from damage due to excessive temperature.
