Oscillators

Oscillators are electrical circuits that can produce periodic, repeating signals, often in the form of a sine wave. They are used in a wide variety of circuit designs, such as clock generators, radio frequency (RF) transmitters, filter networks, and power converters. The ECX-L22CM-155.520 oscillator is a surface-mountable device that is designed for applications such as wireless mobile communication and digital satellite broadcasting.

Working Principle

The ECX-L22CM-155.520 oscillator uses a quartz crystal in an oscillation circuit to produce a high-frequency signal. The crystal oscillator consists of an oscillator circuit and a quartz crystal element, which is a precision component whose size is only a few millimeters. In the oscillator circuit, electronic components such as capacitors and resistors form an LC (inductor-capacitor) circuit. This LC circuit is a resonant circuit that creates resonance when its capacitance and inductance achieve the right balance. The quartz crystal inserted into the oscillator circuit works as an element that determines the resonance frequency. When an AC voltage is applied to this LC circuit, it resonates according to the frequency of the quartz crystal. The application of this frequency generates an oscillation, and the output is taken from the oscillator circuit, enabling it to be used for various circuit designs. The oscillator circuit amplifies the oscillation signals to a usable level of output for the specific application.The ECX-L22CM-155.520 oscillator is an auto-frequency stabilizing device. This means that its resonance frequency changes gradually over time. To counteract this, the internal high-speed microprocessor actively monitors the oscillation frequency, and adjusts the frequency by controlling the inductance and capacitance. This ensures the stable output of a precise frequency.

Application Field

The ECX-L22CM-155.520 oscillator can be used in a variety of communication equipment, such as mobile phones, personal digital assistants, pagers, satellite broadcasting, and so on. The device is also used in frequency control modules for device clock synchronization. It is used in digital broadcasting equipment to ensure accurate Local Oscillator (LO) signal generation, and in wireless communication equipment to generate a stable modulated signal in order to achieve reliable reception. The ECX-L22CM-155.520 oscillator consists of several parts that work together in order to create a stable, precise output. The crystal oscillator consists of a quartz crystal element, a voltage-controlled oscillator circuit, and a high-speed microprocessor monitor. The voltage-controlled oscillator circuit is an LC circuit consisting of an inductor and a capacitor. When an AC voltage is applied to this circuit, the LC circuit resonates according to the frequency of the quartz crystal element. The application of this frequency generates an oscillation, and the output is taken from the oscillator circuit. The microprocessor monitor then adjusts the frequency by controlling the inductance and capacitance in order to maintain a stable output. The ECX-L22CM-155.520 oscillator is highly versatile and can be used in a variety of wireless communication and digital broadcasting applications, such as mobile phones, pagers, personal digital assistant devices, satellite broadcasting, and frequency control modules for device clock synchronization.
