Oscillators

Oscillators play a vital role in modern electronics – from the simple 555 timer circuits to controlling the communications between digital components in sophisticated PCBs. Oscillators are crucial when it comes to producing an electromagnetic signal that is stable and predictable. The term oscillator simply refers to any circuit or device that produces a periodic waveform, such as a sine wave or a square wave. This article is about one specific oscillator—the 530AA173M331DGR.

Application Field of the 530AA173M331DGR

The 530AA173M331DGR oscillator, manufactured by US-based Ecliptek Corporation, is a quartz crystal-based oscillator designed to provide a low power, low jitter, low noise, cost-effective solution for a range of applications. It is a lead-free SMT package that is available in a range of frequencies from 3.2 to 33.0 MHz. The device operates from a low operating voltage of just 2.5V and is RoHS compliant. The 530AA173M331DGR oscillator is ideal for use in wireless infrastructure, communications and networking, and consumer electronics.

Working Principle of the 530AA173M331DGR

The Ecliptek Corporation 530AA173M331DGR oscillator consists of two quartz crystals, a small circuit and a pair of metal plates. When a voltage is applied to the metal plates, the quartz crystals vibrate, producing an alternating electric current. This current is then amplified by the small circuit and the resulting output frequency is determined by the circuits design. This oscillator is known as a quartz crystal oscillator. The most common form of quartz crystal oscillator is an LC oscillator, which is composed of capacitors and inductors.

The 530AA173M331DGR oscillator utilizes the piezoelectric effect of quartz crystals. Quartz crystals are unique in that they exhibit both electrical and mechanical properties. When a voltage is applied to the metal plates of the quartz crystal, the hand-cut quartz crystal vibrates, producing a specific frequency. This frequency is determined by the crystal’s physical characteristics, not the circuit design. Quartz crystal oscillators are very accurate and can maintain a frequency within +/- 15 ppm over a wide range of environmental conditions.

This quartz crystal oscillator is ideal for use in applications requiring accurate and stable frequency control, such as those found in wireless infrastructure, communications and networking, and consumer electronics. Its low power, low jitter, low noise and cost-effective solution makes it an attractive choice for engineers and designers looking for a reliable and accurate oscillator.
