Oscillators

An oscillator is an electronic device or circuit that creates a repetitive, periodic signal. It can generate a sine wave, square wave, triangular wave, or sawtooth waveform. Oscillators are essential components in many types of electronic circuits, such as digital clocks, televisions, radios, and alarm systems. One of the most commonly used oscillators is the ABLNO-125.000MHZ-T, so it is important to understand its application field and working principle.

Application Field

The ABLNO-125.000MHZ-T is a low-noise, straightforward crystal oscillator that is both small and cost-effective. It has a frequency range of 125MHz to 200MHz and can provide a frequency stability of ±0.2ppm in the industrial temperature range (-40°C to +85°C). The ABLNO-125.000MHZ-T has several different packages available including SMD, DIP, and LCC. This makes it suitable for use in a variety of applications such as clock generation, signal generation, and frequency control.

The oscillator has a wide range of uses in consumer electronics, telecommunications, instrumentation, and industrial equipment. For example, it can be used in smart phones, GPS receivers, digital television receivers, set-top boxes, service monitors, LAN switches, radio transmitters, and industrial controls.

Working Principle

The ABLNO-125.000MHZ-T uses a quartz crystal to generate an accurate, stable oscillation at a fixed frequency. The crystal is housed inside a sealed metal case that is hermetically sealed. The case is connected to an electronic circuit that controls the oscillation of the crystal. The circuit board contains two electrodes that are used to apply an electrical signal to the crystal. The electrical signal causes the crystal to vibrate at its resonant frequency.

The oscillation of the crystal is amplified using a transistor and then converted into a digital signal using a phase-locked loop (PLL) circuit. The PLL circuit locks the frequency of the crystal and ensures that it stays steady. The amplified digital signal is then converted back to an analog signal using a voltage-controlled oscillator circuit or gate array. This filtered signal is then sent out to the user devices.

The ABLNO-125.000MHZ-T is a highly reliable, low-cost solution and is used in millions of applications worldwide. Its ease of integration and wide range of frequencies makes it suitable for a variety of applications. Understanding the application field and working principle of the ABLNO-125.000MHZ-T is essential for the successful design and implementation of any system that relies on an accurate, stable oscillator.
