Pin Configurable/Selectable Oscillators: 552AD000270DG Application Field and Working Principle

Oscillators are electronic circuits that generate a periodic, oscillating electronic signal. They are used in many applications such as timers, logic gates and clocks. A pin configurable/selectable oscillator is a type of oscillator that can be configured and selected via its pins.The 552AD000270DG is a Pin Configurable/Selectable Oscillator produced by Renesas Electronics Corporation. It has a jitter of 0.75 ps RMS, offers programmable frequency up to 25.17 MHz, and has a power supply range from 1.8 V to 3.3V. It is a low-cost and low-power solution for applications such as timers, logic gates and clocks.The 552AD000270DG pin configurable/selectable oscillator is a highly versatile device. It has many defining features:• Programmable frequency range from 0-25.17 MHz• Jitter performance of 0.75 ps RMS• Power supply range from 1.8 V to 3.3V• Low-cost and low-power solution• Superior stability and reliability• Wide selection of package types and pin configurationsThe 552AD000270DG pin configurable/selectable oscillator provide users with the flexibility to select a wide variety of frequencies, as well as to set their own frequency ranges. This allows users to tailor the oscillator to their specific application needs. It is an ideal solution for low-power, low-cost applications.The working principle of the 552AD000270DG pin configurable/selectable oscillator is based on a Colpitts oscillator circuit. A Colpitts oscillator is an oscillator circuit that consists of an inductor, a capacitor, and a transistor or multiple transistors.In the Colpitts circuit, the inductor is connected between the transistor’s base and the power source. The capacitor is connected between the transistor’s base and the output signal. When a voltage is applied to the transistor’s base, current will flow through the inductor and the capacitor. This current will create a magnetic field around the inductor. This magnetic field will induce a voltage across the transistor’s base, allowing current to flow again. This cycle will repeat itself and create oscillations. The frequency of the oscillations is determined by the value of the inductor and the capacitor.Typically, the 552AD000270DG is configured using a two-wire Interface that allows users to select the desired frequency and configuration. The two-wire Interface can be used to set the oscillator to a programmed range of frequencies or to set the oscillator to a fixed frequency. It also allows users to control the oscillator’s power supply, output signal, and other features.In conclusion, the 552AD000270DG pin configurable/selectable oscillator provides users with a low-cost and low-power solution for their applications. It features a wide selection of package types and pin configurations, superior stability and reliability, and a programmable frequency range of 0-25.17MHz. The oscillator functions using a Colpitts circuit and can be controlled using a two-wire Interface.
