Crystals

Crystals are the basic building blocks of electronic devices, playing an essential role in the operation of electronic systems. Crystals are used to control frequency and time stability in a wide range of applications including communication, navigation, and industrial production.

Crystals come in a variety of shapes and sizes and have different characteristics depending on their purpose. The 7B-29.4912MBBK-T crystal is a perfect example of a crystal employed in a highly specialized application. It is characterized by its impressive frequency accuracy, low power consumption, and wide frequency range.

7B-29.4912MBBK-T Application Field and Working Principle

The 7B-29.4912MBBK-T is a crystal oscillator manufactured by the UTC Aerospace Systems. It is a temperature compensated crystal oscillator (TCXO) and is mainly used in telecommunications and navigation systems. Specifically, it is used in systems requiring synchronization, such as baseband timing and data transmission in GSM, GPS and CDMA networks.

The 7B-29.4912MBBK-T works on the principles of piezoelectricity. This is the phenomenon in which a mechanical stress applied to a crystal produces a change in its electrical characteristics. When this crystal oscillator is energized, it produces an electrical field and a pressure wave that spreads across the crystals to create a standing wave. This standing wave then vibrates with a frequency determined by the physical characteristics of the crystal.

The frequency of the standing wave is the same as the frequency of the incoming electrical current and is referred to as the input frequency. The oscillator will stay at a steady frequency as long as the input frequency remains constant. The 7B-29.4912MBBK-T is designed to be relatively immune to temperature fluctuations, which ensures that its frequency stays as constant as possible from use to use.

The 7B-29.4912MBBK-T offers a wide range of frequency accuracy and stability, low power consumption, and long-term reliability. It has an impressive frequency range of 8.000 MHz to 55MHz. In addition, it has a wide operational temperature range of -40°C to +85°C. This makes it suitable for use in a wide range of applications, from home use to industry.

The 7B-29.4912MBBK-T also offers excellent performance with low power consumption. It has an average current consumption of 60mA, which is lower than most other crystals in the same range. This helps to reduce the total power usage of the device and ensures a longer battery life.

The 7B-29.4912MBBK-T crystal has proven to be reliable and accurate in a wide range of applications. It is especially popular for its frequency accuracy, low current consumption, and wide temperature range. As a result, it is becoming increasingly popular for use in communication, navigation, and industrial production devices.
