Oscillators

Oscillators are electronic components designed to produce an output signal with a predictable frequency. They are one of the most important active components in electronic circuits.

The 4HF212500Z3AACUGI oscillator is a type of temperature compensated MEMS oscillator (TCMO), which uses a miniaturized oscillator element with a frequency stability of ±2.5 ppm across a wide temperature range from 0 to 70°C. The TCMO approach enables the small size of these oscillators while still providing excellent frequency accuracy. The 4HF212500Z3AACUGI provides a frequency output of approximately 19.2 MHz.

Application Field

The 4HF212500Z3AACUGI oscillator is commonly used in a variety of applications, from consumer electronics to automotive electronics. Specifically, this oscillator is often used in applications that require high frequency accuracy in very limited space. These applications include, but are not limited to, frequency control, low-profile portable devices, Gigabit Ethernet, cellular radios, automotive electronics, and more.

Working Principle

The 4HF212500Z3AACUGI oscillator works by using a micro electro-mechanical system (MEMS) resonator. This resonator is a miniature component that uses highly stressed components made of both crystalline and amorphous materials. When a voltage is applied to the resonator, mechanical vibrations are generated. These vibrations produce an electrical signal, which is used to generate the oscillator output.

The MEMS resonator is the key component of the 4HF212500Z3AACUGI oscillator, and it works in conjunction with other components in order to generate the output signal. Other components include resistors, capcitors, active devices, and inductors. These components all work together to amplify the electrical signal produced by the MEMS resonator, creating the oscillator\'s output. The oscillator then produces an electrical signal with a predictable frequency.

The 4HF212500Z3AACUGI oscillator is a unique and reliable device that provides excellent frequency accuracy and a small footprint, making it well suited for various applications. The MEMS resonator in conjunction with other components makes this oscillator a dependable option for frequency control applications.
