Crystals: 445A35G13M00000 Application Field and Working Principle

Crystals are materials made up of atoms structured into a symmetrical and repeating lattice pattern, which is then subjected to a process of cutting and polishing. This makes them capable of vibrating at a frequency determined by their physical structure. Crystal oscillators are devices that use this property of crystals to generate stable, accurate frequencies needed in many electronic circuits and applications. They are used in countless fields, ranging from radio and consumer products to medical and military devices.

Application Field of 445A35G13M00000

The 445A35G13M00000 series of crystal oscillators are part of the 7-pad surface mount oscillator series available from Mouser. It has the following applications:

• Timing and synchronization for consumer electronics such as TVs, DVD players, computers, GPS systems and cell phones.
• Test and measurement applications, such as frequency counters and time domain reflectometers.
• Manufacturing processes, such as in automated assembly line systems.
• Industrial applications, such as manufacturing and process control.
• Defense, maritime and aerospace applications, such as navigation and communication.

Working Principle of 445A35G13M00000

The working principle of the 445A35G13M00000 crystal oscillator involves the combination of two main elements. The first is the crystal itself which consists of a quartz slice cut in a specific way to make it precisely tuned to a particular frequency. This crystal is then combined with an oscillator circuit to produce a signal with a very precise frequency. This is achieved by using a feedback loop in the oscillator circuit that amplifies the crystal’s frequency to give a stable signal output.

The oscillator circuit consists of active components like transistors and capacitors, and passive components such as resistors. It creates electrical oscillations at its output terminal, which can be used for timing. The frequency of this oscillation is determined by the frequency of the crystal.

The 445A35G13M00000 series of crystal oscillators offer a frequency stability of ±50ppm (parts per million). They also feature a low phase jitter of 150fs (femtoseconds), which makes them ideal for digital audio and high-speed digital applications, such as Gigabit Ethernet and Fibre Channel systems.

Conclusion

In conclusion, the 445A35G13M00000 series of crystal oscillators are highly accurate components used in a wide range of electronic applications. They offer a precise, stable frequency and low phase jitter, making them suitable for modern devices and systems that require a high level of precise timing.
