Crystal oscillators are widely used andapplied in consumer and communication applications ranging from inexpensive watches, to long-range and high-frequency communication through satellites. One of thelatest crystal oscillator types is the GL200F35CDT, a MEMS based Crystal Oscillator. This article will detail the application field and working principle of the GL200F35CDT Crystal Oscillator.

The GL200F35CDT Crystal Oscillator uses a MEMS pressure resonator that is designed to provide superior long-term aging and temperature stability performance while requiring no external tuning. This allows the oscillator to operate over a wide operating temperature range with minimal to no drift in frequency and makes it an ideal solution for applications that require long-term accuracy such as GPS, medical and industrial instruments. The oscillator also runs on low voltage allowing for a compact design with minimal power consumption.

The working principle of the GL200F35CDT is based on the frequency control of the mechanical oscillator. The resonator consists of a small square SiNx membrane mounted on top of the oscillator chip. This membrane is attached at the centerwith an anchor point and is suspended between four electrical contacts. When an electrical potential is applied between two of the contacts, the membrane deflects, creating a resonance frequency. This resonance frequency is then used to control the frequency of the oscillator.

The GL200F35CDT Crystal Oscillator is designed to operate between 1.71 - 45 MHz and is available in a CMOS or LVDS output. This allows the user to select the desired frequency while maintaining a low power consumption. The oscillator also provides a range of options such as pull or push-pull oscillations, operation in single, dual or triple frequency modes, and a sync or lock input. These features make it a versatile solution for time and frequency applications.

In conclusion, the GL200F35CDT Crystal Oscillator is a MEMS based oscillator that offers superior long-term aging and temperature stability, low voltage operation and a wide range of options. Its frequency control is based on the mechanical oscillator, where an electrical potential is applied between two contacts causing a resonance frequency that is used to control the frequency of the oscillator. This makes it an ideal solution for time and frequency applications.
