It is also able to take up a wide voltage range from 3.0V to 5.5V and is designed to operate in temperatures ranging from -45℃ to +125℃. Furthermore, the device is packaged in a 24-pin QFN package.

Working Principle

The working principle of 4HF133330Z3AACUGI is based on the design of crystal oscillators. It uses a quartz crystal as a resonator to produce a stable and accurate frequency. The external inductor (L1) and two capacitors (C1 and C2) oscillate and generate the required frequency. The crystal is connected to generate a frequency signal that is divided by a 1/N counter and the output signal is fed back to the input oscillator. The oscillator produces a square wave signal that is utilized to drive the output frequency of the crystal.

The circuit on the chip includes a crystal oscillator, a prescaler, a phase detector and a voltage controlling oscillator (VCO). The crystal oscillator is connected to the prescaler which divides the frequency output of the crystal by external capacitors, resistors and inductors. The output of the prescaler is then inputted into the phase detector which is used to compare the frequency of the divided output with a reference frequency to adjust the phase of the output signal to match the output of the crystal. The output of the phase detector is then fed back into the VCO which produces the required frequency oscillations.

In addition, the 4HF133330Z3AACUGI device also includes an internal voltage regulator, which allows for low-noise, low-power operation. The device also includes a temperature compensated crystal oscillator (TCXO) which helps to maintain the accuracy of the frequency signal over a wide temperature range. The device also has a wide range of temperature compensation options, such as digital controlled temperature compensation, manual temperature compensation, temperature pulse width modulation (PWM), and gain setting. This allows the user to select the optimal frequency stability and performance over wide temperature range.

In summary, 4HF133330Z3AACUGI is an oscillator used in applications such as radio, television, cell phone, satellite communication, microwave communication, clock generators and test equipment. Its working principle is based on the design of a crystal oscillator using a quartz crystal as a resonator along with an internal voltage regulator and temperature compensation options. 4HF133330Z3AACUGI offers high-speed performance and is designed to operate in temperatures ranging from -45℃ to +125℃.
