Oscillators

Oscillators are electronic systems that generate a periodic signal, such as a sine wave, triangle wave, sawtooth or square wave. They are used in a variety of applications, ranging from controlling the speed of electric motors to generating radio frequencies. In this article, we will discuss the application field and working principle of the 655L156G3C3T oscillator.

Application of 655L156G3C3T Oscillator

The 655L156G3C3T oscillator is a low-cost solution for applications which require a temperature-stable performance. It is especially suitable for microprocessor-based hardware designs as it is able to drive modern high-speed memory devices, which can help reduce software overhead. This oscillator is also used in systems which require accuracy, such as medical equipment, government installations or precision engineering. This oscillator combines the low power consumption, low cycle-to-cycle jitter, and exceptional frequency stability of a crystal oscillator, along with the fast startup of a voltage-controlled oscillator.

Working Principle of 655L156G3C3T Oscillator

The working principle of 655L156G3C3T oscillator is based on the power-on reset (POR) architecture. It consists of a 14-bit counter and a voltage-controlled oscillator (VCO). Upon power-on, the 14-bit counter will increment every cycle, according to the timing scheme. The timer will then take the output of the VCO as its input, and the output frequency of the timer will be determined by the phase of the VCO output. As the VCO output phase is affected by external environmental factors such as temperature, the output frequency of the oscillator varies from cycle-to-cycle, resulting in a low-speed jitter.

Conclusion

The 655L156G3C3T oscillator offers a low-cost solution for applications which require a temperature-stable performance and accuracy. It combines the low power consumption, low cycle-to-cycle jitter, and exceptional frequency stability of a crystal oscillator with the fast startup of a voltage-controlled oscillator. It’s working principle is based on the power-on reset (POR) architecture, and consists of a 14-bit counter and a voltage-controlled oscillator (VCO).
