All You Know about Electronic Crystal Kits

You can buy Electronic Crystal Kits to make your quartz crystal oscillators. These kits contain all the components you need to build your crystal oscillators, including a PCB (printed circuit board) that measures 3.0" x 1.5". These kits also contain a crystal tester and can be used as a building block for homemade circuits. Unlike other kits, you do not have to solder your crystals!

Piezoelectric Resonators

The most used piezoelectric resonators in electronic Crystal Kits products are extensional and transverse. Extensional mode resonators have electrode pairs that are continuous along the plate's length and width. Opposing electrode pairs are separated by a gap that runs the length of the plate. The two electrode pairs can be driven by opposing currents to produce a varying frequency.

This type of crystal has a variable signal level, determined by an oscillating circuit. This allows one crystal to be used for various chips that require different clock signal voltages. The advantage of this type of crystal is that they are more inexpensive than other types of resonators. They are also more accurate, ranging from 1 ppm to 100 ppm. Therefore, they are ideal for amateur electronic crystal kits.

Pierce Oscillator

A Pierce Oscillator is a basic electronic oscillator circuit. It is especially well-suited for crystal oscillator circuits. The Pierce oscillator is named after its inventor, George W. Pierce (1872-1956), and it is a descendent of the Colpitts oscillator. Because of the relatively low cost of manufacturing and its outstanding frequency stability, this oscillator circuit is commonly used in digital IC clocks.

To understand how this circuit works, you need to understand the three components that make up a ring oscillator. The first part is the crystal itself, and the second is the circuit's XO active core. In both cases, the crystal has a motional resistance, CSHUNT, and an electrostatic capacitance. The total capacitance is then equal to C0. The three components make up the circuit, and it is only the ring capacitance that is different.

Quartz Crystal Oscillator

A quartz crystal oscillator's output frequency is usually a fundamental resonance or exactly multiple of the fundamental frequency. Crystals exhibit several modes of oscillation, which are known as overtones. These modes are approximate, not exactly, multiples of the fundamental frequency. To create a frequency signal, you need to combine these overtone modes. You can create a ringing sound or a pulsating one with a quartz crystal oscillator.

The frequency of a crystal depends on its mass and how it is connected to a load. A low CL leads to RF phase noise that is degraded. Additionally, the frequency of start-up time becomes longer. If you're planning to build a radio-frequency oscillator, the frequency can be increased by increasing the mass of the two electrodes. However, it is not recommended to scratch the electrodes to increase the frequency, as it can damage the crystal and lower its Q factor. An alternative method is to use capacitor trimmers to adjust the frequency of the oscillator circuit.

TCXO

There are two basic types of TCXO components: JT-series and T-series. The former feature an external adjustment that allows the frequency to be periodically reset, removing the effects of crystal aging. However, both types of TCXOs have problems with temperature compensation. Because they are high-Q elements, the adjustment range is limited, and a voltage regulator is needed to avoid unwanted temperature effects and frequency shifts.

TCXO oscillators are available in two basic types: analog and digital. Analog models achieve temperature compensation by constructing a peripheral network that complements the crystal oscillator's temperature coefficient. Meanwhile, digital systems use a temperature sensor to measure and store data about temperature. Digital versions can boast higher frequency stability and wider temperature compensation intervals than analog models. To determine the proper TCXO for your project, you should purchase a TCXO Electronic Crystal Kit.

OCXO

OCXO Electronic Crystal Kits are a popular choice for DIY electronic projects. These kits provide everything you need to build a crystal oscillator and a programmable digital timer. Oscillators are used in electronics projects to generate precise clock signals. A well-built OCXO will give you the accuracy and frequency you need in any application. An OCXO is an important component of many electronic devices, and they are an essential part of every circuit.

The OCXO is much larger than a simple crystal oscillator and requires a thermistor to measure ambient temperature. It also requires a heat source, such as a power transistor or resistor. A comparator circuit controls the amount of power to the heat source, and the OCXO itself is temperature-sensitive. The resistor and op-amp in the circuit are controlled with thermostats, so the OCXO needs a relatively low power input to operate.
