Oscillators – 550JE100M000DG Application Field and Working Principle

Oscillators are essential components for producing and controlling signals in telecommunications, computers, robotics, and other electronic devices. They are also used extensively in RF and microwave applications. The model 550JE100M000DG is a digital oscillator that operates in the frequency range of 0.01 Hz to 100 MHz. This versatile product provides a clean and reliable signal with low frequency and power dissipation.The 550JE100M000DG offers an excellent combination of features and performance, including low noise levels, low jitter, wide temperature range operation, high shock and vibration tolerance, and high accuracy. It also has a wide frequency range which is adjustable in 1.0 kHz steps. The device can operate in dual and single-ended modes and is compatible with a variety of communication systems.The 550JE100M000DG is typically used in radio, television, satellite receivers, cellular telephones, amplifiers, navigation systems, and in the military applications. It can also be used in the construction of bandwidth-limited systems, distortion cancellers, active digital filters, frequency synthesizers, delay lines, and other precision applications.The 550JE100M000DG is a crystal-controlled, direct digital synthesis (DDS) oscillator with a single frequency. Its core is based on a sigma-delta modulator architecture in which the clock signal is divided into two equal sub-cycles. The first sub-cycle is used to determine the phase and the second sub-cycle is used to control the frequency. Frequency adjustments are made by changing the size of the first sub-cycle. This is done by either adjusting the phase of the clock signal or by changing the divider ratio of the counter.The 550JE100M000DG oscillator has two built-in low-power amplifiers. The first amplifier is used to boost the phase shift signal from the sigma-delta modulator. The second amplifier is used to take the amplified signal and convert it into a square wave with adjustable frequency. The amplifier also includes a limiter and a feedback circuit to maintain a stable oscillation.The 550JE100M000DG oscillator has a built-in temperature-compensated temperature sensor to ensure stable operation over a wide temperature range. It also has a digital random noise generator designed to reduce low spurious frequency components. The oscillator is also equipped with a high-performance Automatic Gain Control (AGC) circuit which adjusts the available output power for optimum performance.The 550JE100M000DG oscillator is designed for easy integration into existing systems and is available in a variety of packages. The device is designed to meet the requirements of the international MIL-STD-883 standard for Crystal Oscillators. It is also capable of operating in an extended temperature range from -55°C to +125°C. The wide range of features, including low current draw, small size, and high reliability make the 550JE100M000DG a versatile digital oscillator suitable for use in a variety of applications.
