Introduction

Crystals are widely used in all kinds of electronic applications due to their precise frequency control and fast switching capability. This article will discuss the modern application fields and working principles of the 416F400X2CTT crystal oscillator, which is widely used for electronic circuit designs.

What is the 416F400X2CTT Crystal?

The 416F400X2CTT crystal oscillator is a crystal oscillator manufactured and sold by Fox Electronics Corporation. It is a precision tuning-fork oscillator that comprises a two-piece construction with two miniature tuning inserts. The tuning inserts are scaled down versions of their bigger tuning fork counterparts allowing them to operate with a full-scale oscillation frequency of 400KHz when powered under a 9V operating voltage.

Application Fields of the 416F400X2CTT

The 416F400X2CTT crystal oscillator has a wide range of applications, including being used as the clock source in several types of electronic systems. It can be used in microcontrollers, digital signal processors, pulse width modulators, mobile phones, and other consumer electronics as well. The 416F400X2CTT has also found applications in military and aerospace hardware and in robotic systems. One of the main advantages of the 416F400X2CTT compared to other crystal oscillators is its high operating temperature range and stable frequency behavior. This makes it ideal for use in situations where temperature stability and frequency stability are particularly important such as in satellite communication systems. The 416F400X2CTT is also highly accurate, with a frequency tolerance of +/- 0.35 ppm and an amplitude stability of 0.01 dB. This makes it suitable for use in precision frequency control applications such as in quartz clock movement circuits. The 416F400X2CTT is also used in medical implantable device control circuits due to its high accuracy and stability.

Working Principles of the 416F400X2CTT

The 416F400X2CTT crystal oscillator produces a stable reference frequency for electronic circuit designs. It is vibration-controlled and works just like a tuning fork. The tuning forks are placed between two fixed points, and when a voltage is applied, the tuning forks start to vibrate at their natural frequency. The frequency of the oscillations produced by the tuning forks is then used as the reference for the electronic circuit. The 416F400X2CTT crystal is designed to be temperature stable, so it can maintain an accurate reference frequency even in extreme temperatures. The 416F400X2CTT crystal oscillator also employs super-resolution techniques which allow it to produce a more accurate reference frequency than other types of crystals. This makes it ideal for applications where precision is of utmost importance such as in satellite communication systems.

Conclusion

The 416F400X2CTT crystal oscillator is a widely used precision tuning-fork oscillator that is used in a wide range of applications. It is highly temperature stable and accurate, making it suitable for use in satellite communication systems, medical implantable device control circuits, quartz clock movement circuits and other frequency control applications. It works by producing a stable reference frequency using the vibrations from two tuning forks when a voltage is applied. The 416F400X2CTT also employs super-resolution techniques for an even more accurate reference frequency.
