Oscillators are electronic circuits used in various applications such as timing signals, voltage regulation and communication. Among them, the VG-4231CE 28.3116M-CQEM is a miniaturized yet highly reliable quartz clock oscillator capable of providing accurate timing with a signal integrity rate of up to 5ppm. This article will give an overview of VG-4231CE 28.3116M-CQEM’s application fields and working principle.

VG-4231CE 28.3116M-CQEM is mainly used in the application areas of communication equipment, precision timing and high frequency applications. In terms of communication, it is frequently used for radio frequency (RF) communication due to its high frequency stability and low power consumption. Besides, it is often utilized in critical timing applications where accuracy, stability and impact resistance are most important, such as satellite communications, avionics, ship navigation, broadcasting, healthcare and computer peripherals. As for high frequency applications such as Bluetooth®, Wi-Fi® and 4G/5G communication, VG-4231CE 28.3116M-CQEM provides excellent signal clarity and reliability that is significant in avoiding potential interference from other devices.

VG-4231CE 28.3116M-CQEM follows a very simple digital oscillator circuit configuration. Inside the quartz-glass-package which is hermetically sealed, a temperature-compensated crystal oscillator (TCXO) is located. This TCXO is made up of four components: a quartz crystal, a pair of feedback capacitors, a diode detector and an operational amplifier. It starts to oscillate when an alternating signal is applied to one of the electrodes, making the quartz crystal vibrate at a specific frequency. The frequency of oscillation is determined by the resonant characteristics of the quartz crystal and is strongly affected by temperature. By combining two of these elements with an adjustable resistor, the inherent frequency stability can be compensated and improved.

With the help of the TCXO, VG-4231CE 28.3116M-CQEM generates very precise signals at a higher frequency and faster rates than most conventional quartz oscillators. On the other hand, the relatively high stability of the oscillator allows it to provide a very precise and stable signal even in a highly fluctuating environment, which makes it an ideal choice for precision timing. In addition, the device also utilizes a high-end hermetic packaging which further increases its resistance to shock and vibrations.

In conclusion, VG-4231CE 28.3116M-CQEM is a highly reliable and precision miniature quartz clock oscillator that is capable of providing accurate timing with a signal integrity rate of up to 5ppm. It is mainly used in communication, precision timing and high-frequency applications. The device is based on a very simple digital oscillator circuit with a temperature-compensated crystal oscillator at its core and utilizes a highly-reliable hermetic packaging to ensure high stability and impact resistance.
