416F38012IDR Application Field and Working Principle

Crystals are a key component in many electronic circuits. These tiny components require precise manufacturing and highly engineered substrates in order to deliver accurate, reliable performance. The 416F38012IDR is a type of miniature crystal oscillator designed specifically for use in telecommunications applications, providing stability and reliability.

Application Field

The 416F38012IDR is an extremely small crystal that has an operating temperature range of –40 to +85°C. It is designed for use in legacy and next-generation telecommunications applications such as cellular phones, digital trunked radio networks, private branch exchange (PBX) systems, and digital signaling processors. It is engineered to fit within tight space requirements and is compatible with various low-voltage IC interfaces.

Working Principle

The 416F38012IDR utilizes a basic oscillator principle known as “tuning fork” design. A metal tuning fork-shaped resonator is cut along its two tips, causing it to vibrate at a precise frequency. This frequency is determined by the size and shape of the crystal, as well as its temperature. A driving voltage is applied to one of the tips to cause it to vibrate, and the other tip is connected to a circuit that detects the vibrations. This circuit is calibrated to produce an output frequency equal to the resonance frequency of the crystal.

The 416F38012IDR is designed to have a frequency stably within the range of 12.65 MHz to 12.80 MHz, with a frequency tolerance of ≤ ±0.5 ppm over the entire operating temperature range, allowing it to be used in many high-precision timing circuits as well as telecommunications applications.

Conclusion

The 416F38012IDR is an industry-standard crystal oscillator designed specifically for use in telecommunications applications. It utilizes a tuning fork-style resonator and is quite small, making it suitable for use in limited space requirements. Its high-accuracy performance makes it well-suited for use in related applications such as cellular phones, digital trunked radio networks, and PBX systems.
