Oscillators are electronic circuits that generate a periodic waveform. Oscillators are widely used in the communications and electronics industries, as well as in computer controlled systems. The DSC1124CI5-156.2578 is an oscillator that features a very accurate crystal timebase and operates with an external voltage supply range of 12.5 to 28 volts.

Application Field

The DSC1124CI5-156.2578 is used in a wide range of applications including radar systems, medical devices, navigational and instrumentation systems, telecommunications equipment, aerospace systems and automotive systems. Furthermore, it can be used in a broad range of frequencies, from 4KHz up to 5Ghz. Additionally, it is a widely used oscillator for verifying the accuracy of communications networks and for testing complex circuit configurations.

Working Principle

The working principle of the oscillator is based on a basic design that combines both analog and digital techniques. The oscillator\'s clock frequency is determined by a precise crystal-controlled timebase, while the amplitude of the output signal is determined by a DAC (digital-to-analog converter) controlled by an onboard current-to-voltage converter (I/V). As the I/V\'s input reference voltage changes, the oscillator\'s frequency will increase or decrease proportionally with the amount of voltage applied. The DSC1124CI5-156.2578 can also be used in a Mode Select mode in which the frequency can be altered by adjusting an internal bias voltage.

The oscillator\'s oscillatory output signal is handled by a preamplifier stage that converts the signal into a stronger, more predictable form that can be used by downstream systems. After conversion, the signal is passed through a low-pass filter to remove unwanted noise that may be present in the waveform. The filtered signal is then sent to downstream amplifiers, mixers, and other circuitry, where it is used as a reference signal for the various components.

The signal output is synchronized to the timebase frequency so that it is synchronized and accurate. Changes in voltage or frequencies are detected and held in the device\'s timebase registers and passed as addressable signals to subsequent circuitry. As such, the oscillator can be easily integrated into a variety of challenging applications that require a reliable frequency reference.

The DSC1124CI5-156.2578 provides an extremely stable clock reference, and is remarkably tolerant to temperature and voltage perturbations. This makes it particularly suitable for applications where accurate and reliable operation is required such as those found in the aviation, defence, and medical fields. Finally, the oscillator\'s robust design and wide operating temperature range ensure its reliable operation over long periods of time.
