Crystals are used throughout many electronic industries, from cell phones and radios to global navigation systems. ABL-LR-12.288MHz-T crystal is an example of a popular crystal used for a variety of applications. This crystal is constructed from quartz, and ranges from a frequency of 12.288 - 12.500 MHz throughout its range of temperatures. The fundamental mode of operation consists of delivering a highly consistent signal with a frequency of 12.288 MHz regardless of any temperature changes that occur.

ABL-LR-12.288MHz-T application field covers many sectors, including industrial, consumer and automotive industries. Industrial and consumer applications mainly involve triggering and timing requirements of radio frequency and microprocessors, such as consumer electronics and laptop computers. Industrial applications may incorporate triggering and timing needs in industries such as, medical imaging and other medical equipment. Automotive applications typically focus on clock signals necessary in many embedded controller systems.

The working principle of this crystal can be better understood by looking at cutaway diagrams and analyzing an individual crystal, as well as understanding its respective oscillation mode. The resonator includes a quartz crystal and headpiaces. The quartz crystal is protected from any mechanical stress or shock by the headpiaces, which are traditionally comprised of springs. The quartz crystal is mounted between the headpieces and has electrical contact points on its top and bottom.

When an electrical signal is applied to the contact points of the quartz resonator, a series of vibrations are produced in the crystal. These vibrations cause a resonance frequency to occur that can range anywhere from 12.288 to 12.500 MHz depending on temperature conditions. This frequency range is further impacted by changes to the logic chips, programming, and power levels connected to the crystal.

The resonance frequency is further impacted by the mounting of the quartz resonator. Poor mounting mechanisms may be responsible for signification frequency variances, thus affecting the overall run time of the device. It is recommended that the quartz crystal be firmly encapsulated in a glass or ceramic resonator to reduce any vibration interference from its surroundings.

ABL-LR-12.288MHz-T crystal is a versatile crystal with a range of applications in various industries and sectors. Its fundamental mode of operation is driven by the quartz resonator, which is sensitive to variations in temperature and logic chips and programming connected to the crystal. Properly mounting the crystal, along with glass or ceramic encapsulation, can assist in preserving the consistent frequency of 12.288MHz despite any temperature changes that may occur during operation.
