Oscillators

Oscillators are circuit elements which can provide an output signal which oscillates, or fluctuates, at a predefined rate. One of the most common applications of oscillators is to generate alternating current (AC) electrical signals. Strictly speaking, an oscillator is an amplifier with feedback that is used to produce a periodic output signal. Oscillators are widely used in many radio, audio, and electronic applications. But the technology is more than just a useful tool, which explains why it has gained so far application in modern times.

XLL73V056.000000I application field and working principle

The XLL73V056.000000I Oscillator is a multifunctional oscillating system which works under three distinct modes: temperature compensated crystal (TCXO) oscillator mode, voltage-controlled crystal (VCXO) oscillator mode and oscillator pulse generator mode. It is designed to work with two independent supply voltages of 2.3V and 5V, which can be constant or varying. The device is based on a CMOS integrated circuit integrated over a quartz crystal. The main principles of operation of XLL73V056.000000i are as follows:

• The oscillator contains two independent oscillator circuits, which are connected in parallel to the same crystal. The first circuit is a frequency-variable, voltage-controlled oscillator, and the second circuit is a temperature-compensated crystal oscillator tuned to a fixed frequency.
• The frequency-variable oscillator works on a PLL (Phase Lock Loop) principle. An oscillation voltage is generated by an external voltage, and this voltage is compared to the output voltage of the PLL circuit. When they are in balance, the loop is locked, and the oscillation frequency is stabilized. The voltage-controlled oscillator works on a frequency-control principle, where an oscillation voltage is generated by controlling the bias current of the external voltage.
• The temperature-compensated crystal oscillator is designed to maintain a constant frequency even under different temperature conditions. The oscillator has a built-in temperature-compensation circuit which compensates the frequency according to the variation in temperature.

The XLL73V056.000000i Oscillator has a wide range of potential applications in electronic systems. It can be used for the generation of very stable output signals for use in frequency control, timing control, and phase synchronization systems.
