588S130X2ITT APPLICATION FIELD AND WORKING PRINCIPLE

An oscillator is an electronic circuit or device with a continuous output signal, generated by the periodic, often harmonic, oscillations of a system. The 588S130X2ITT Oscillator is a state-of-the-art precision oscillator used in a wide variety of applications, spanning multiple industries. Most notably, it has been widely used in aerospace and defense industries, where its status as one of the most reliable available has made it the go-to choice in many cases.

The 588S130X2ITT is an oven controlled crystal oscillator designed to provide frequency stability in the order of ±1.0x10-6/year to the user. It has a frequency range of 10 to 125 MHz, and is capable of operating within an extreme temperature range of -55°C up to +125°C. All of this may sound complicated, but don’t worry - the technical details will be discussed further down.

In addition, a few of its notable features include extremely low phase noise of -122 dBc/Hz at 10 Hz offset, extremely low jitter of 1 ps at 10 KHz to 1 Gb/s, and extremely low current consumption of 8 mA for the smallest 1.25 V device package.

At its core, the 588S130X2ITT is based on the same fundamental principle as any other oscillator. This is illustrated with the following simple schematic:

The 588S130X2ITT itself may be quite different in terms of complexity and number of components, but the same principle applies at the core and it is this fundamental concept that we shall explore in this article.

At its fundamental level, the 588S130X2ITT oscillator revolves around the use of feedback in a system in order to produce a signal. Unlike other oscillators, this particular one focuses more on using crystal technology in order to provide frequency precision. This is achieved by taking advantage of the Piezoelectric effect which allows it to produce an oscillating signal at a precise frequency.

At the heart of the 588S130X2ITT is a crystal resonator, which is a specialized quartz crystal encased in a metal casing. The crystal oscillates in response to an applied electrical voltage, creating an oscillating electric field. This alternating electric field causes the crystal to physically vibrate at the same frequency, creating an oscillating current which is then used to drive the feedback circuit.

The autotuning circuit is then used to adjust the feedback circuit such that it produces the desired output frequency. This is done by comparing the output frequency with an internal reference. If the two differ, the feedback is adjusted until they match; at which point it is stable and will continue producing a signal at that frequency with extreme stability and precision.

In conclusion, the 588S130X2ITT is an extremely reliable and precise oscillator, ideal for use in extreme industrial applications. The combination of crystal technology, autotuning circuits, and carefully chosen components combine to make a very stable and accurate oscillator, capable of operating within an incredibly wide temperature range.
