Crystals have been an integral part of electronics since the early days of the telephone. Today, crystals play a central role in almost every electronic application, such as providing the stable frequency output used to time events and generate high accuracy signals, or even acting as the heart of a watch. The 416F520X2ADR oscillator is a silicon piezo-electric crystal oscillator specifically designed for low-power, low-noise applications.

An oscillator is an electronic device that generates periodic electrical signals in a predictable, periodic manner. It consists of a resonator, like a quartz crystal, and an amplifier. A crystal oscillator works through the phenomenon of piezoelectricity, which is the ability of certain crystals to generate an electrical charge in response to mechanical pressure. Quartz and other piezoelectric materials consist of an axis of atoms arranged to form a lattice that, when force is applied, the crystal vibrates along its axis at a specific frequency, creating a voltage.

The 416F520X2ADR oscillator is designed specifically to operate at frequencies between 2 and 142.875MHz, making it ideal for high-precision applications, including radio frequencies, digital signal processing and broadcast timing. Its low power consumption—as low as 5mA—combined with its low noise makes it an ideal choice in embedded systems where power and space are limited.

The oscillator works by taking a quartz crystal and connecting it to an amplifier, which is a device that converts a low-voltage input (the oscillator\'s output) into a stronger signal. The quartz crystal and amplifier form a feedback loop: when the output of the amplifier is fed back into the quartz crystal, it vibrates at its resonant frequency, which then generates a voltage. This voltage is compared to a reference signal that is generated by the amplifier, and if there is a difference between the two, the oscillator adjusts its output frequency until it matches the reference.

The 416F520X2ADR oscillator is a reliable and cost-effective solution for low-power, low-noise applications. Its small size and low power consumption make it well-suited to embedded systems and its robust design makes it ideal for harsh operating environments. It is commonly used in a variety of applications including handheld devices, automotive systems, mobile communication devices, and video game consoles.
