Crystals: 416F40623ILR Application Field and Working Principle

Crystals offer a variety of applications in the field of electronics and engineering due to their electrical and mechanical properties. The 416F40623ILR, also known as the Industrial Low Ripple Frequency Crystal, is a type of crystal developed by ICMS, specifically designed for the industrial, automotive, and telecommunication markets. This article covers the application field and working principle of the 416F40623ILR crystal.

Application Field

The 416F40623ILR crystal is an electronic component that provides a highly precise frequency reference for many electronic circuits, ranging from micro-devices to larger power control systems. The crystal is suitable for use in commercial, military and industrial applications due to its features, including: low operating temperature range (-40ºC to 85ºC); tolerance range of +/- 15ppm; and a maximum frequency of 125MHz. The 416F40623ILR crystal is designed to be used in a variety of different applications, such as: clock generators, microprocessors and microcontrollers, digital signal processors, power supply unit, frequency counter and communication equipments. The crystal is also used in mobile, satellite and automotive communication systems, allowing users to benefit from high-quality reception and transmission.

Working Principle

The 416F40623ILR crystal works by converting an applied voltage into a precise, predictable frequency. The crystal is tuned to a specific frequency, referred to as its “fundamental frequency”. When the voltage supplied to the crystal is increased, the vibration frequency is increased to a point where unwanted harmonics are generated. To reduce the harmonics and to maintain a stable frequency output, the 416F40623ILR crystal includes two partially conductive crystals and two capacitors connected in series.When an alternating voltage is applied, the two crystals vibrate at their resonance frequencies, generating two separate outputs of opposite phases; this is referred to as “mode locking”. By combining the two outputs, a single, high-precision frequency is produced and all the unwanted harmonics are cancelled out. The capacitors are used to adjust the amplifier gain and can also be used to help dampen the vibrations, thereby reducing the harmonics.

Conclusion

The 416F40623ILR crystal is a powerful and reliable frequency reference suitable for a range of industrial, military and commercial applications. Its low operating temperature range and tolerance range make it a great choice for sensitive applications that require a high degree of accuracy and stability. The crystal\'s working principle leverages the properties of its two internal crystals and capacitors to generate a stable, precisely tuned frequency output, while eliminating any unwanted harmonics.
