Oscillators are essential for many electronic circuits and devices. FJ2400002 is an oscillator IC, which is used in a wide range of applications. In this article, we shall discuss the application field and working principle of FJ2400002.

The FJ2400002 has been designed for applications in the automotive, industrial, medical, and consumer markets. It can be used in interfaces, control modules, automotive entertainment systems, medical monitors, and telecommunications equipment. This oscillator IC offers very low power consumption, high accuracy, and cost effectiveness.

The working principle of FJ2400002 is based on the phase-locked loop (PLL) technique. In this technique, an input signal is compared to an internal reference signal, and any difference is used to create a corrective action. The main components of PLLs include a phase/frequency detector (PFD), a loop filter, and a voltage-controlled oscillator (VCO). The PFD compares the signals and its output is then sent to the loop filter, which determines the frequency of the VCO.

The FJ2400002 contains both the PFD and the VCO, as well as a set of other features, such as an on-chip crystal oscillator, power-down mode, and fast transient response. This IC is capable of operating over a wide supply voltage range, from 1.8V to 5.5V. It has a programmable operating frequency ranging from 10MHz to 260kHz, and a maximum phase noise of -105dBc/Hertz.

FJ2400002 also offers several advanced features. These include temperature compensation for optimum stability, crystal-less operation for low cost, and a wide duty cycle range of 40% to 90%. Furthermore, the IC features a low supply current, with a typical value of 140μA, and a low output jitter of 2ps RMS.

In summary, FJ2400002 oscillator IC is designed for a broad range of applications, from consumer devices to automotive systems. Its low power consumption and high accuracy make it a cost-effective solution for many projects. The IC is based on the PLL technique, with an on-chip crystal oscillator, power-down mode, and other features. Finally, it offers temperature compensation, crystal-less operation, and a duty cycle range of 40% to 90%.
