Oscillators are running a variety of electronic applications: from communication and navigation systems to robot controllers and remotely monitoring systems. Among them, the LFSPXO018077Bulk oscillator stands out as an example of a dependable, energy-efficient component to be used in all these applications.

The LFSPXO018077Bulk oscillator is an advanced quartz crystal oscillator with high frequency stability, low power consumption, and long life reliability. Featuring high stability, the LFSPXO018077Bulk runs for eight years without device failure, and has a frequency stability rate spread of ± 0.1ppm over an operating temperature of -40 to +85˚C - ideal for mission-critical and harsh environments.

In addition to its strong frequency stability, the LFSPXO018077Bulk offers a wide range of power supply options, from 1.8 to 3.3 V, and extremely low power consumption: only 0.3 milliwatts (mW) at 1.8 V and 5 mW at 3.3 V, making it ideal for battery-powered applications. The LFSPXO018077Bulk also features excellent phase noise and jitter characteristics, achieving an average frequency of 900 MHz. On the outside, the LFSPXO018077Bulk features a small footprint size of 5 mm x 3.2 mm that allows for easy design-in.

But how does it work? There are two main components in a quartz crystal oscillator that allow it to generate a stable frequency: the crystal material gently vibrates at its resonant frequency within a closed loop system; and the oscillator circuit which amplifies the crystal output signal and produces the necessary output waveform.

In the case of the LFSPXO018077Bulk, a tiny quartz crystal is enclosed within a hermetically sealed container and contained within the oscillator circuit. The circuit is designed to select a specified output waveform depending on the application requirements, usually a sinusoidal wave, and also filters out a number of unwanted frequencies and noise.

The quartz crystal and the oscillator circuit is combined together to form a two-stage LC oscillator network that produces a very stable oscillatory waveform. The oscillator circuit also includes a number of components that stores energy and supports the static electricity needed to keep the oscillator frequency constant over time.

The frequency of the output waveform is determined by the resonant frequency of the quartz crystal. This resonant frequency is mathematically determined by a series of combinations of inductors and capacitors in the LC network, so that the resultant frequency of the waveform is always within the operational parameters. This stability is especially important in applications such as embedded systems and communications where accuracy is paramount.

To sum up the main features and working principle of the LFSPXO018077Bulk oscillator, it has outstanding frequency stability, an expansive range of power supply options, a tiny footprint, and draws a negligible amount of power. All these characteristics make it an ideal choice for many applications.
