Oscillators

Oscillators form the cornerstone of many electronic circuits, providing the essential time base or frequency reference signals for many systems. They come in a wide variety of types and shapes, ranging from RC and LC oscillators to specialized crystal oscillators, such as the KC7050Y125.000L20EZU. This article will provide a brief description of its application field and working principle.

Application

The KC7050Y125.000L20EZU is an R-C oscillator, designed to operate in the frequency range of 100 kHz to 2 MHz in a variety of different applications. It is primarily used as a reference oscillator for precision frequency measurement or as a timing generator for precise timing applications. It is an ideal choice for frequency counters, digital clocks, frequency synthesizers, radio communication systems, and many more.

Working Principle

The R-C oscillator is based on the basic principle of the voltage-controlled oscillator. It consists of a resistance-capacitance (RC) network, which is driven by a voltage source. The RC network acts as an electrical filter, blocking and passing certain frequencies, leading to the formation of a resonant frequency, which is determined by the values of the components. The frequency of the oscillator can be adjusted by varying the resistive and/or capacitive elements of the RC circuit.

The KC7050Y125.000L20EZU consists of a resistor and a capacitor connected in series. It has an operating frequency of 125 kHz and a temperature stability of 0.06 ppm/K (-30°C to 70°C). It is a CMOS voltage-controlled oscillator, capable of producing low jitter, high accuracy and low noise signals. The output frequency can be tuned by applying a voltage to the TTL-compatible control input.

Conclusion

The KC7050Y125.000L20EZU is a versatile R-C oscillator, well suited for a wide range of applications such as precision frequency measurements and timing generators. It is based on the basic principle of the voltage-controlled oscillator and utilizes an RC network to produce a resonant frequency, which can be adjusted by varying the values of the resistors and capacitors. This oscillator is highly accurate, offering low jitter, low noise, and temperature stability of 0.06 ppm/K (-30°C to 70°C).
