Oscillators: FN2700074 Application Field and Working Principle

Oscillators are essential components of modern electrical circuits that generate a repetitive or oscillating signal at a harmonic frequency. As such, they are used in a variety of fields, ranging from radio transmission and cellular broadcasting to instrumentation and environmental monitoring. In particular, FN2700074 oscillators are versatile, low-cost digital integrated circuits (ICs) that are widely used in commercial and home applications.

The FN2700074 oscillator is a versatile, low-cost three-pin, CMOS-based IC designed to function as a clock generator. It utilizes a fixed-frequency loop that delivers a highly stable frequency output from 1 MHz to 100 MHz. The device operates from a 5V supply voltage and exhibits low-noise and high-accuracy performance over an industrial temperature range from -40 to +85℃.

The oscillator is a self-contained unit, with a built-in R-C oscillator circuit consisting of a resistor, capacitor, and transistor. The transistor works as an amplifier, amplifying the signal present on its base to finally send a high-frequency output signal, proportional to the resistance and capacitance of the form. The resistor determines the frequency of oscillation, whereas the capacitor determines its stability and accuracy.

The FN2700074 oscillator has an output enable (OE) pin, which, when driven low, disables the output. It also features a positive-edge reset (PR), which can be used to reset the device. The oscillator also features an internal pull-up/pull-down resistor which can be used to help pull the OE or PR pin up or down, depending on the circuit requirements.

One of the advantages of FN2700074 oscillators is their low-noise performance. The device features a noise floor of -130 dBc/Hz at a 1MHz output, with a very low output jitter of just 0.5ps RMS. This ensures that it is suitable for precision applications where low noise and high accuracy performance is required.

FN2700074 oscillators are widely used in clock-generation applications such as sensors, detectors, control systems, and base-station applications. They are also used in wired and wireless communication systems, due to their low-noise performance and high accuracy. Additionally, the oscillators are also used in medical devices, where their low-noise and high accuracy features are important in ensuring the proper functioning of the device.

In summary, FN2700074 oscillators are versatile and low-cost digital integrated circuits that are widely used in commercial and home applications. They feature a built-in R-C oscillator circuit consisting of a resistor, capacitor, and transistor, and feature an output enable (OE) pin and positive-edge reset (PR) pin. The devices are used in clock-generation applications, such as sensors, detectors, and communication systems, as well as medical devices, due to their low-noise and high accuracy performance.
