416F40011CLT

Application Field and Working Principle

The 416F40011CLT crystal is a special type of quartz crystal oscillator that can automatically maintain a consistent frequency of vibration. It is widely used for general purpose and communication circuit applications, in particular for cellular base station receivers and transmitters, as well as for precision timing for aerospace, aviation and missile systems. The 416F40011CLT is a surface mount package, and a leaded version (416F40011CLT-15) is also available.

Applications

The 416F40011CLT crystal is commonly used for general-purpose applications such as clock generators, frequency synthesizers, high-end data communication systems, lasers, and automatic test equipment. Moreover, the surface mount package makes it suitable for precision timing and high-frequency applications in mobile phones, base stations, and mobile data systems. Additionally, its low-power operation and fast settling time enable it to be used in high-speed circuits such as fiberoptic links and optical switches.

Working Principle

Quartz crystals are made of an alloy composed of silicon and oxygen (SiO2), which is compressed into a thin disk with metal electrodes. The metal electrodes act as an electrical capacity and the disk keeps them separated. When an alternating current is applied, the alternation of charges causes the metal electrodes to vibrate, thus creating an oscillating electrical signal. This oscillating electrical signal is amplified and converted into an accurately timed electrical signal, which is used to control the operation of digital devices (such as microprocessors and other digital logic).

The 416F40011CLT crystal is designed to work exactly in the same way as described above, with one exception: it uses a special “floating oscillation” circuit to maintain its accurate frequency. This circuit monitors the temperature of the surrounding environment and adjusts the operating frequency in real-time to compensate for any drifting due to temperature changes. As a result, the oscillation of the 416F40011CLT crystal can be held with an accuracy of 1 parts per million (ppm) or better.

Conclusion

The 416F40011CLT crystal is a reliable and accurate Quartz Crystal Oscillator that is widely used in both general purpose and communication circuit applications. Its surface mount package and floating oscillator circuit make it suitable for precision timing and highly-accurate frequency control in a variety of high-speed applications. As a result, the 416F40011CLT crystal is an important component in maintaining accuracy and reliability in devices such as cell phones, base stations, fiberoptic links, and other digital devices.
