Crystals are a very essential element in modern world. From the electrical circuits to computer chips, they are absolutely necessary to all these architectures. Recently, there is an emerging kind of crystal oscillator, called GL300F35IET, which is becoming more and more popular. Its application field and working principle will be introduced below.

GL300F35IET’s application field mainly resonates to the high precision timekeeping and portable communication device, such as mobile communication and positioning navigation. As it is particularly designed for satellite timing, GL300F35IET’s precision storage timer could keep the station for long term, even for years, ensuring users get enough precise data to help on their calculations. The operating temperature is -30℃ to +85℃, which is especially suitable for satellites since they are out of Earth’s atmospheric range. Its strong temperature performance ensures it is reliable and resistant to peripheral environment.

Talking about its working principle, simply speaking, GL300F35IET acts as a metronome with its high oscillation frequency, generally running over 10 MHz. As a quartz crystal based oscillator, the regular oscillation of GL300F35IET is generated by electromagnetic wave excited by voltage. A quartz crystal vibrates due to the piezoelectric effect and the resonant frequency is fixed by its dimensions, material and cut. The vibration in the crystal is then sent through transmission line and into the tuning circuit, which matches up the current running through the crystal to the resonant frequency. This helps establish and stabilize the frequency of the oscillator to ensure high precision timing.

GL300F35IET’s steady frequency output also has high immunity to aging. As long as the quartz crystal is not significantly damaged, its oscillations will remain constant. In addition, GL300F35IET uses open-loop frequency detecting, in which the frequency detector pulses the reference quartz crystal’s oscillation and uses the pulse’s width and fall to adjust the output frequency. As this method requires no comparison with an external reference oscillation, its stability is inherently higher than other clocks and no temperature compensation circuit is needed either. By probing the subject quartz crystal’s output once in a while and adjusting the output frequency, GL300F35IET can provide an actual and ever-precise timing output.

Therefore, GL300F35IET can provide excellent timing effect in satellite navigation system, digital telecommunication and other high precision timing applications. With its steady frequency output and resistant to temperature performance, GL300F35IET can be a reliable partner for these devices. As a state-of-the-art crystal oscillator, GL300F35IET is an indispensable component for more and more upcoming devices.
