Quartz crystals are most commonly found in communication systems, timer circuits, and temperature measurement systems. One specific product—the 7M40000129 frequency control quartz crystal—is a popular choice, due to its range of features, reliability, and affordability.

The 7M40000129 crystal is a surface mount device that is very similar to the industry standard 7M40000125. This type of crystal is used for a variety of applications including digital frequency synthesis, high-speed sampling, direct digital synthesis (DDS), and other types of sophisticated frequency control. It has the ability to yield stable frequencies, even in extreme environmental conditions. The 7M40000129 frequency control quartz crystal can be used in digital systems, such as frequency synthesizers, that require high frequency stability and accuracy.

The 7M40000129 crystal utilizes a continuous wave oscillator and frequency multiplying/dividing principle. The crystal is mounted on a ceramic plate, and the electrical leads are connected to the crystal directly. A sinusoidal voltage is applied across the crystal and the frequency is determined by the crystal\'s resonant frequency. Frequency variation can be achieved by increasing or decreasing this voltage, which changes the capacitance of the crystal and altering the resonant frequency. For a given voltage, the resonant frequency of the crystal can vary from a few kilohertz to several gigahertz depending on the type of crystal used.

The 7M40000129 crystal also utilizes a spread spectrum technique. This mechanism reduces radio frequency interference by spreading the frequency of the signal. The signal is spread over a wider frequency range and hence avoids interference from other signals in the same frequency range. This technique also allows the frequency of the signal to be more accurately measured, since it eliminates the need for adjusting the crystal frequency.

The 7M40000129 crystal offers several advantages. It is relatively low cost and easy to use. The oscillator circuit used with the crystal is simple and highly accurate.
