Programmable Oscillators

Programmable Oscillators are special electrical circuits that generate a periodic, repeating signal, often however, it is necessary to be able to adjust the frequency and other characteristics of the output waveform in response to either external stimuli or events, to provide greater control over the timing and operation of the device, circuit or system in which the oscillator is used. One of the most important components of programmable oscillators is the SIT9005ACU1D-25SN Programmable Oscillator. This oscillator is based on Smart Timing LLC\'s patented "Very-Low-Phase-Noise" (VLPn) technology, and provides a high precision output frequency without any need to trim or adjust the fundamentals, harmonics, or sub-harmonics. This oscillator can be programmed to output signals at frequencies ranging from 8kHz up to 200MHz, with adjustable amplitudes and pulse widths, depending on the application or system requirements. The primary benefit of the SIT9005ACU1D-25SN is that it eliminates the need to continually adjust frequency and other characteristics of the output waveform in order to achieve the desired performance.

Application Field

The SIT9005ACU1D-25SN programmable oscillator is ideally suited for diverse commercial, industrial, and military applications. It is widely used in systems where precise frequency control and stability is desired, including in military and aerospace systems, high-speed data communications networks, RF and microwave instrumentation, medical diagnostic equipment, and precision instrumentation. The SIT9005ACU1D-25SN is also suitable for applications such as test and measurement, avionics, and navigation.

Working Principle

The working principle of the SIT9005ACU1D-25SN is based on Smart Timing LLC’s patented "Very-Low-Phase-Noise" (VLPn) technology. This technology provides a high precision output frequency without any need to trim or adjust the fundamentals, harmonics, or sub-harmonics. Smart Timing’s VLPn technology works by making slight modifications to the signal output from the programmable oscillitory, improving the signal-to-noise ratio, and increasing the accuracy of the signal output. These modifications involve modifying the waveform shape, removing unwanted spectral components, and optimizing the signal\'s spectral purity.

The SIT9005ACU1D-25SN features AVX proprietary Automatic Frequency Control (AFC) feature, which allows user to easily program the desired frequency. It also includes an automatic gain control (AGC) feature with adjustable sensitivity to improve signal stability and accuracy. The AFC/AGC feature ensures that any frequency variations due to temperature fluctuations or aging components are automatically compensated.

The SIT9005ACU1D-25SN also offers a number of other inherent advantages over other programmable oscillators, such as excellent phase noise, low spurs, low power consumption, and excellent short-term frequency stability. It has a maximum output power of 30dBm, which enables greater signal stability, and improved accuracy of the waveforms produced. Additionally, the SIT9005ACU1D-25SN provides an ultra-low jitter performance of up to 0.4ps for improved precision of the waveforms created, making it an effective sensor for applications such as nuclear medical instruments.

In conclusion, the SIT9005ACU1D-25SN Programmable Oscillator features outstanding performance and provides a high-precision output frequency without any need to trim or adjust the fundamentals, harmonics, or sub-harmonics. With its high precision and automatic frequency and gain control features, this oscillator is optimized for use in diverse applications such as aerospace and medical instrumentation, and communications networks. The SIT9005ACU1D-25SN is an ideal solution for applications where precise frequency control and stability is desired.
