Introduction

Crystals are one of the most versatile materials used in modern electronic applications, from timing circuits and resonators to oscillators and piezoelectric-based transducers. Knowing the various types available, their physical characteristics and how they work can help electricians and engineers make the right choice when selecting a crystal. This article examines the application field and working principle of one type of crystal in particular, the LFXTAL003102BULK.

Application Field

The LFXTAL003102BULK is a high-performance crystal that operates at frequencies of up to 102kHz. It is ideal for applications such as clock and timing generators, precision noise filters and frequency dividers. It is also used in a number of deriving frequency circuits, such as voltage-controlled oscillators, phase-locked loop oscillators, frequency synthesizers and temperature-compensated crystal oscillators.

Physical Characteristics

The LFXTAL003102BULK is a small 4-pin quartz-based crystal that measures 4.6 mm x 1.8 mm x 0.9 mm (L x W x H). It features a high-Q factor of 3500, a low aging rate and a low series resonance impedance of 1 ohm. The clock frequency accuracy of the LFXTAL003102BULK is +/- 10 ppm. The range of operating temperatures is between -20°C and +70°C.

Working Principle

The LFXTAL003102BULK uses quartz-based crystals that resonates at a precise harmonic frequency in the range of 0-102 kHz. It contains two plates of quartz that are connected in a series with two external pins. The quartz crystal acts as a circuit element to maintain the frequency of oscillation of a circuit at a given point. When a periodic voltage is applied to the crystal, it vibrates at its natural frequency. This vibration further induces an oscillatory current in the circuit. As a result, the oscillations of a circuit remain at the natural frequency of the quartz crystal even when a varying voltage is applied.

Conclusion

The LFXTAL003102BULK is a versatile quartz-based crystal that features a wide range of applications and a high-Q factor. It has a low impedance, a low aging rate and a frequency accuracy of +/- 10 ppm. With its small size and wide temperature range, the LFXTAL003102BULK is ideal for a variety of electronic applications such as frequency dividers, precision noise filters and voltage-controlled oscillators.
