Oscillators: XLL530400.000000X Application Field and Working Principle

XLL530400.000000X (“XLL”) is an oscillator type used in various sensing applications. It is a direct voltage controlled, low frequency (absolute low frequency or ALF) two-terminal oscillator. It consists of three components: two inductors and a resonator. It offers a variety of benefits, including low power consumption, low noise, a wide frequency range and a wide temperature range. In addition, it has a self-compensation feature to prevent it from drifting with temperature and supply voltage changes.

Application Field

XLL is a highly integrated oscillator for various applications, such as position and speed measurement, vibration, temperature and humidity sensing, and navigation. The main application fields of XLL oscillators include embedded systems and home/office automation, automotive-related applications, medical instruments and equipment, industrial automation, and industrial and consumer electronics.

Working Principle

The main components of a XLL oscillator are two inductors and a resonator. The inductors are connected from the input to the output of the oscillator, and the resonator is connected to the opposite ends of the inductors. The inductors are magnetically coupled and create an impedance. As the magnetic field created by the inductor combination fluctuates (due to the oscillation of the crystalline resonator), it causes the inductance to drop and oscillate between the output and ground. This instantly creates an AC voltage across the supply, resulting in an oscillating voltage wave.

The operating frequency of an XLL oscillator is determined by the inductance and capacitance values of the integrated circuit. The inductors increase the inductance of the circuit, whereas the resonator decreases the inductance. The resonator also serves as the frequency voltage canceling device, which helps maintain the oscillation frequency by creating a filter effect over the range of the oscillation frequency.

The XLL oscillators are designed for high-precision performance, with a low power requirement, low noise level, and wide temperature range operation. In addition, due to its self-compensation feature, the oscillator can be used in applications without suffering from drifting with temperature and supply voltage changes.
