GL200F33CET

GL200F33CET Application Field and Working Principle

The GL200F33CET crystal is an AT-cut resonator from Murata that operates at a frequency of 33.000MHz±30ppm tolerance. The crystal is often used in Very High Frequency (VHF) applications for functions such as oscillation, filtering, and pass/stop bandwidth control. It is heavily used in consumer devices such as Mobile phones, Radio Transceivers, and Narrowband Modems.

The GL200F33CET functions as a major component of an oscillator circuit and is essential in generating a signal that can oscillate at the desired frequency, in this case 33.000MHz. The fundamental principle upon which it operates involves changing the capacitance and inductance of the crystal to generate a signal at the target frequency. This is done by using an external oscillator circuit that interacts with the crystal to produce a signal.

When a signal is fed into the crystal, its capacitance and inductance change due to the effect of the signal. This generates a voltage across the crystal, and this voltage is then fed into the resonator. The resonator is the equivalent of an amplifier and it serves to amplify the signal generated by the crystal. The amplified signal is then fed back into the crystal and the cycle repeats, creating a cycle of oscillations at the target frequency.

The GL200F33CET has characteristics such as a low series resistance and a high frequency stability. Its low series resistance ensures that it does not draw more power from the system than is necessary, as it does not absorb the excitation signal. The high frequency stability enables it to hold the oscillations at a consistent frequency and tempo, ensuring that electrical signals can be transmitted reliably.

The crystal is also designed to be used in an environment with high temperatures and can handle temperatures from -20°C to 85°C without any problems. This makes it useful in a wide variety of environments and applications. All these features make Murata\'s GL200F33CET an ideal choice for various electronic applications.
