Crystals

A crystal is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. Crystals typically form symmetrically and have a well-defined external face, being at the same time a natural and orderly arrangement.

In electronics, crystals are used in a variety of applications such as oscillators, filters, and amplifiers. One such application is the 402F19222IAT, an integrated clock oscillator. The 402F19222IAT consists of an oscillator circuit built on a single silicon die, sealed in a hermetically sealed package. The device uses an FT32VN5-5LN crystal, which is tuned to a frequency of 10.75 MHz.

402F19222IAT Application Field

The 402F19222IAT is an ideal choice for applications that need reliable clock oscillators for a variety of clock speeds, including high-speed CPUs, DSPs, FPGAs, and ASICs. It is also well-suited for automotive and industrial electronics, medical equipment, and network routers. The device features low power consumption, low static power, and a wide operating temperature range (-40°C to +85°C).

402F19222IAT Working Principle

The 402F19222IAT utilizes a quartz crystal, a device that responds to an electrical signal of a certain frequency and then transmits back an identical frequency. When the crystal is placed in a parallel resonance LC circuit, the crystal will oscillate at its resonant frequency. This process is known as quartz crystal oscillation. The oscillator circuit of the 402F19222IAT is designed to maintain the quartz crystal at its resonance frequency of 10.75 MHz. The oscillator circuit also includes a power amplifier that boosts the signal enough to overcome the conduction losses in the output stage to produce a high frequency clock signal.

The oscillator circuit includes a low pass filter, which eliminates any unwanted signals from the circuit, providing stable and reliable clock signals from the 402F19222IAT. As the temperature changes, the quartz crystal’s frequency changes and the circuit adjusts for those shifts in frequency.

Conclusion

The 402F19222IAT is a reliable and cost-effective clock oscillator built on a single silicon die, sealed in a hermetically sealed package. The device is designed for a variety of applications, including high-speed CPUs, DSPs, FPGAs, and ASICs. It utilizes a quartz crystal to oscillate at a frequency of 10.75 MHz and includes a power amplifier and a low pass filter that eliminates any unwanted signals, ensuring stable and reliable clock signals.
