DSC1101CI2-066.6667 Application Field and Working Principle

Introduction

Oscillators are electrical components that generate an alternating output signal through self oscillation, usually in the form of a sine wave, in the vicinity of a specific resonant frequency. Different oscillator types vary from those powered by direct current, to those sensitive to and powered by a signal input. One of such oscillators is the DSC1101CI2-066.6667.

Application Field

DSC1101CI2-066.6667 oscillators, supplied by Data Device Corporation (DDC), are incorporated within a variety of applications found in industrial, networking, military, mission-critical and medical systems, including radar, electronic warfare, communications, and mission-critical applications.

Avionics

Given its noise-cleaned and temperature-stabilized feature, the DSC1101CI2-066.6667 is particularly well-suited for avionics applications. Specifically, DSC1101CI2-066.6667 oscillators operate as reliable Clock Time Domain Reflectometers (TDRs) at up to 28GHz and can be effectively used to amplify and modulate an optical input.

Synthesizers

DSC1101CI2-066.6667 oscillators can also be used in quad-synthesizers, as required in radar and communications systems, for synchronizing, timing and frequency chain operations.

Radar

The high accuracy and repeatability of the DSC1101CI2-066.6667 makes it an ideal component for radar systems, where low jitter performance and high Spurious Free Dynamic Range (SFDR) is of paramount importance – the oscillator is capable of providing 125dB SFDR over 24GHz with minimal jitter and harmonics down to 131dBc (kHz to GHz).

Working Principle

The working principle of DSC1101CI2-066.6667 oscillators is based on voltage-controlled frequency and phase methods. The oscillator can be controlled via loop filters, for both frequency and phase modulation. The oscillator is powered using the crystal and RF input that is integrated on the oscillator board. The power is then converted into frequency by the crystal, and the phase and frequency are controlled by the input signal. The output of the oscillator can be further modified in terms of frequency by the feedback loops from the device. DSC1101CI2-066.6667 also works with noise-cleaned technology, meaning that signal noise that occurs due to environmental and temperature variations is removed from the output, making it more accurate and reliable.

Conclusion

The DSC1101CI2-066.6667 oscillator from DDC is widely used across avionics, synthesizers and radar systems due to its low jitter performance, high Spurious Free Dynamic Range (SFDR) and low harmonic distortion. The oscillator\'s working principle is based on voltage-controlled frequency and phase methods, and utilises crystal and RF integration on-board. Overall, the DSC1101CI2-066.6667 oscillator provided by DDC is an ideal component for mission-critical, industrial, networking, military and medical applications.
