Crystals are specialized components used in electronic circuits for their ability to oscillate at a desired frequency with a high degree of accuracy and stability. The AV-24.305MDQY-T crystal manufactured by Abracon LLC is one example of a small, low-cost, and high-precision crystal device used in modern electronic circuits. In this article, we will discuss the application field and working principle of the AV-24.305MDQY-T crystal.

The AV-24.305MDQY-T is an open-designed crystal, which means that its quartz structure is embedded in an opaque and molded metal case with an exposed metal contact. This design is optimum for applications that require high-frequency tuning and good frequency stability over a wide temperature range. The AV-24.305MDQY-T is used primarily in consumer electronics and other low-cost applications that require precision timing. It typically measures 0.22" (5.7 mm) by 0.24" (6.0 mm) in size and is rated for 12pF to 50pF load capacitance.

The AV-24.305MDQY-T operates on the principles of oscillation. Oscillation occurs when the electrical energy is coupled back into the device to create an oscillating magnetic field, which in turn drives the quartz crystal. This process is further enhanced by the fact that the quartz crystal has a very low elastic modulus, meaning its shape responds readily to external force. As a result, the AV-24.305MDQY-T crystal exhibits a very stable and accurate oscillating frequency.

The AV-24.305MDQY-T crystal is mainly used in voltage-controlled oscillators (VCOs) and frequency control units (FCUs). VCOs are used in circuitry to generate signals of varying frequency over a range, while FCUs maintain a predetermined frequency with low-noise and high-stability. In addition, the AV-24.305MDQY-T is also used as a timing element in microcontrollers, computers, and communications systems, as well as in analog and digital clocks.

The AV-24.305MDQY-T crystal boasts a frequency stability of ±20 ppm over a total temperature range between -40° C and +85° C, a frequency accuracy of ±30 ppm, and an average long-term stability of ±10 ppm, making it one of the most accurate and stable crystal oscillators on the market. This device also offers excellent EMI shielding performance, making it suitable for applications involving high levels of electromagnetic interference.

In conclusion, the AV-24.305MDQY-T crystal is a small, low-cost, and high-precision crystal oscillator that is primarily used in consumer electronics and other low-cost applications that require precise timing. It is capable of generating a very stable and accurate oscillating frequency and offers excellent EMI shielding performance. As such, it is an ideal choice for precision timing applications in microcontrollers, computers, and communications systems, as well as in analog and digital clocks.
