353LB5C307T

Introduction

The 353LB5C307T is a oscillator which is categorized as a crystal oscillatoror quartz oscillator. It is a small size planar crystal monolithic oscillator which is highly resistant to shock and vibration and features a wide in operating temperature. It utilizes quartz crystals to obtain highly precise oscillations.

Application Field

The 353LB5C307T is widely used in systems requiring high accuracy such as telecom, navigation, medical equipment, and automotive. It is often used for synchronizing the clock generated signals coming from the host equipment, for tuning of radio frequency signals, and for sample and hold circuit tuning.

Working Principle

The 353LB5C307T oscillator operates on the principle of piezoelectric effect. The quartz crystal starts vibrating when certain voltage difference is applied between the two sides of the crystal. The quartz crystal is cut and shaped in such a way that it will vibrate at its resonating frequency. The frequency of the oscillations depends on the loading capacitance of the crystal. The quartz oscillator also emits electrical signals at the same frequency, which can be used as reference signals.

The quartz oscillator consists of two parts, the quartz crystal and an electronic circuit. The quartz crystal is connected to the electronic circuit. When a voltage difference is applied across the crystal, it starts vibrating and produces an AC voltage called Proof Mass Voltage (PMV). This PMV is coupled to the electronic circuit, which amplifies it and sends it to a sinusoidal signal output. The frequency of this output signal is determined by the resonant frequency of the quartz crystal. The frequency can be tuned by changing the external capacitance connected to the crystal.

The crystal oscillator also incorporates temperature compensation circuitry which ensures that the frequency remains consistent over the operating temperature range. This is a very important feature in many applications such as GPS and telecom.

Conclusion

The 353LB5C307T oscillator is a highly accurate and reliable oscillator. It is widely used in systems requiring high accuracy. Its output signals are generated based on the principle of piezoelectric effect. Its frequency is tuned using external capacitors and the oscillator is protected against temperature variations.
