Crystals

Crystals are widely used in modern communications, from basic radio transmitters to intricate applications such as radar, medical imaging, and optical communications. As such, there are a wide variety of crystal types, from basic quartz crystals to the more complex temperature compensating crystals.

When it comes to temperature compensating crystals, one of the most commonly used is the 9B-48.000MEEJ-B. This type of crystal is commonly used in a variety of applications ranging from frequency control in telecommunication transmitters to clock synchronization in integrated circuits. However, to understand how this type of crystal works, it is important to have a good understanding of the underlying principles of operation.

Application Field

The 9B-48.000MEEJ-B is a frequency control application type of crystal, meaning it is used to maintain frequency accuracy in radio transmission even if the outside environment changes. This ensures that radio transmission remains stable, reliable, and accurate regardless of the changing conditions. One of the more notable applications involves the use of the crystal in digital cellular technology, such as in cellphones. Other applications include timing and synchronization in microprocessors, clock accuracy in military and public safety radios, and external clock frequency accuracy in satellite devices.

Working Principle

How does the 9B-48.000MEEJ-B crystal work? At its most basic level, the 9B-48.000MEEJ-B crystal is a piezoelectric device, meaning it responds to applied mechanical stresses. The crystal consists of two quartz plates, one with an internal metallization that is used as an electrode. When an alternating electrical signal is applied to the quartz plates, the crystal will vibrate. The frequency of the signal is determined by the quartz plates’ dimensions and the thickness of the metallization layer. As the temperature of the environment changes, so too will the frequency of the crystal.

To counter this effect, the crystal is designed to incorporate a temperature compensating element. This element, when combined with the quartz plates, will cause the crystal’s frequency to remain stable despite changes in temperature. In other words, the frequency of the crystal will always remain at the same frequency, regardless of the environmental changes. This ensures that transmission and synchronization remains accurate despite environmental changes.

The 9B-48.000MEEJ-B is a type of frequency control application crystal, and its working principle is based on piezoelectricity and temperature compensation. This type of crystal is used in many types of applications, from cellphones to satellites, to ensure that transmission and synchronization remains accurate despite environmental changes.
