Crystals

Crystals are components found in a variety of electronic and communication devices. They are used as oscillators, filters, frequency and phase control devices, and as information storage and retrieval elements. The7B-12.288MBBK-T crystal from TT Electronics is a quartz crystal that operates at 12.288 MHz frequency with a fundamental motional series equivalent to 10–13s. Quartz crystals are widely used for this frequency due to their low cost, stability and temperature performance.

Application Field and Working Principle

The 7B-12.288MBBK-T crystal from TT Electronics has a package size of 7x5 mm, and is ideal for a range of applications that require the accurate delivery of signals and data such as in telecom systems, smart cards, automotive, and media players. The crystal operates within an oscillator circuit, where it is used to provide an accurate reference frequency. An oscillator circuit consists of three main components: an amplifier, a filter, and the crystal which works as a resonator. The amplifier produces an alternating current that passes through the filter which in turn excites the quartz crystal.

The quartz crystal within the oscillator circuit acts as a piezoelectric material which vibrates at a given frequency depending on the size of the material and the frequency required. When the alternating current passes through the crystal it causes it to vibrate at the frequency of the current. The frequency of the alternating current is then determined and amplified by the amplifier and the filter. This exact frequency is then used as the reference signal. It is this frequency that is used to ensure accuracy of the application in which the crystal is being used.

The 7B-12.288MBBK-T crystal from TT Electronics provides excellent frequency stability over a wide range of temperatures, enabling it to be used in a variety of application fields.
