Oscillators, such as ASTMUPCFL-33-26.000MHZ-EY-E-T3 are the devices used to generate electrical signals. These are classified into LC, RC, PT and Crystal models, depending on their working principle. ASTMUPCFL-33-26.000MHZ-EY-E-T3 is a LC oscillator which is specifically designed to generate a sinusoidal signal for providing clock to processors, memories, peripheral drivers in communication systems. As electronic systems require exact clocks to produce correct signals for transmitting a data, these oscillators are required.

A LC Oscillator, as the name suggests, requires an inductor with a capacitor in its circuit. This circuit is capable of producing sinusoidal output when powered with steady DC supply. This oscillator requires two capacitors and one inductor for its working. Its input is provided through two input pins. The output of the oscillator is taken from a third pin. Its oscillatory frequency is determined from formula ‘f=1/2π√LC’. Here, L is inductance of the inductor in inductor capacitor (LC) tank circuit of the oscillator and C is the capacitance of the capacitor in the same circuit.

ASTMUPCFL-33-26.000MHZ-EY-E-T3 oscillator is designed to work with an input voltage of 3.3V, typically. Its frequency can be adjusted to 26MHz with a capacitor in the tank circuit and an amplitude of 0.4V peak to peak sinusoidal output. It has relatively high stability and can be used for wide range of frequencies. Due to its small size, it can be mounted on the Printed Circuit Boards (PCBs). Again, the frequency provided from the signal of this oscillator is quite accurate as compared to an RC oscillator.

In order to choose the right value of an inductor and capacitor in the tank circuit, the required oscillatory frequency should be provided to it. This can be done by preparing a frequency versus capacitance graph and using an extrapolated value, for instance the graph can be plotted for frequency versus1/capacitance.Then, from this graph a plot of desired frequency is identified in parallel to the vertical line. After that the capacitance value can be determined from the corresponding intercept.

The function of an oscillators like ASTMUPCFL-33-26.000MHZ-EY-E-T3 can be explained by considering an ideal situation of its tank circuit. Here, power supply is provided to the circuit at 0.5V. Varying capacitor and resistor values produce different oscillatory frequencies. A inductor is mandatory in this system as it resists change of current flow in the circuit, thereby allowing current to oscillate. Thus, it keeps the same range of frequencies for a given circuit.

The main application field of ASTMUPCFL-33-26.000MHZ-EY-E-T3 is in providing the clock to processors, memories and peripheral drivers in communication systems. It can also be used for producing high frequency clock signal for digital and analog circuits. Moreover, based on its size and design, it can be used to generate precise time in ovens, clocks, timers etc. In short, this oscillator provides a steady clock in an electronic system and hence its application range is very wide.
