Oscillators
Oscillators are electrical circuits that generate repeating waveforms. They are used extensively in a variety of applications such as sound synthesis, electronics testing, and telecommunications. While there are a variety of oscillator types, they all share the basic concept of oscillation, or the production of repeating waves over a period of time.
The SG-8018CG 18.4320M-TJHSA0 is a low-jitter, low-power, and low-noise oscillator that is specifically designed for embedded systems. It operates between 18.4320MHz and 19.2699MHz, and offers an output frequency stability of +/-0.5ppm over a +5V to +3.3V voltage range. It also features a low supply current of 8mA, as well as a jitter of 0.5psrms.
Applications
The SG-8018CG 18.4320M-TJHSA0 is best suited for applications where accuracy and low power consumption are essential. These could include microprocessors and digital signal processing (DSP) systems in mobile phones, digital cameras, automobiles, and the medical field. In addition, this oscillator may also be suitable for telecommunication systems, such as DSL modems and Ethernet routers.
Working Principle
The SG-8018CG\'s oscillatory function is based on a Pierce oscillator. This type of oscillator utilizes a combination of an LC (inductor-capacitor) circuit and an active element. The LC circuit forms an oscillation generator, while the active element provides the necessary gain for sustaining the oscillations.
The oscillator begins by ramping up the power in the LC circuit until it reaches a level sufficient to sustain oscillations. When this happens, the active element amplifies this signal, and the LC circuit now acts as an oscillator amplifying and sustaining itself. This process is repeated over and over again, producing the oscillatory waveforms.
Conclusion
The SG-8018CG 18.4320M-TJHSA0 oscillator is a low-jitter and low-power oscillator designed for embedded systems. It operates between 18.4320MHz and 19.2699MHz, and offers an output frequency stability of +/-0.5ppm over a +5V to +3.3V voltage range. It can be utilized for a wide variety of applications, and its operation is based on the well-known Pierce oscillator principle.
