Oscillators are electronic devices that produce a continuous output signal. They are used in many applications such as communication systems, control systems, test and measurement, sensing, and medical equipment. The DSC1001CI2-027.0000 is one such oscillator. It is a voltage-controlled oscillator (VCO) with an adjustable frequency range from 1 MHz to 130 MHz.
The DSC1001CI2-027.0000 consists of an oscillator core, an output buffer, and a voltage-controlled Varactor diode. The oscillator core uses the LC tank circuit, which is connected in series between two gates of an N-MOS transistor. A charging resistor across the two gates stabilizes the oscillations in the LC tank circuit. The Varactor diode allows a voltage-controlled tuning of the LC tank circuit, resulting in a frequency-to-voltage characteristics.
The output signal is buffered using an impedance-matched active buffer, which increases the output power while preserving the input signals purity. An additional low-pass filter is connected at the output stage eliminating any potential signals that appear outside of the desired frequency range.
The performance of the oscillator is further improved by using sigma-delta modulation techniques. This results in a higher frequency resolution ratio, increased frequency accuracy and improved phase noise performance. Moreover, the modulation technique is used to reduce the power consumption of the oscillator.
To ensure that the output signal of the oscillator is within the desired frequency range, the DSC1001CI2-027.0000 is equipped with various frequency stabilization features. These features are PLL (Phase-Locked Loop), calibration-based auto-tune techniques, and an open loop frequency adjustment.
The PLL circuit is used to lock the output signal to a reference frequency. When locked, the frequency of the output signal will remain constant within certain limits regardless of the input differences. The calibration-based auto-tune technique utilizes the capacitance of the Varactor diode and the charging resistor to create a micro-tuning technique. In this technique, the oscillator core works in open-loop mode, and the output signal is monitored using a voltage feedback loop.
The open loop frequency adjustment feature allows the user to make manual adjustments to the output frequency. This feature also helps in compensating for any drift in the oscillator due to temperature, loading or other environmental influences.
The DSC1001CI2-027.0000 is a widely used oscillator due to its wide frequency rangeas well as its high reliability and robustness. It can be used for communication systems, control systems, test and measurement, monitoring, sensing, and medical purposes. Its wide frequency range and voltage-controlled varactor diode provide reliability and flexibility when used in different applications.
