Programmable Oscillators are well suited for a variety of applications, including frequency synthesis, frequency state selection, and precision frequency control for test & measurement and radio systems. The SIT9005ACB1H-XXDB Oscillators is a programmable multiple-output oscillator, providing frequency synthesized and state-selected outputs.

The SIT9005ACB1H-XXDB is used in a number of different applications due to its versatility and reliability. It can be used to generate frequencies from 8kHz up to 33MHz. It is commonly used in consumer electronics, military and aerospace systems, automotive navigation systems, and communications circuits. The multiple-output oscillator allows users to generate different frequencies in different components with a single device, saving board space and cost. The SIT9005ACB1H-XXDB also boasts a low power consumption and is ESD protected for operation in electrically sensitive environments.

The working principle of the SIT9005ACB1H-XXDB is based on a programmable system that uses digital signals to control a quartz crystal oscillator. This system, called a Direct Digital Synthesizer (DDS), receives digital codes that define the frequency, operational mode, and other parameters of the oscillator, then use this information to generate the desired output. The DDS uses a digital-to-analog converter (DAC) to convert the digital codes into analog waveforms, then feeds this data to the quartz crystal oscillator. The quartz crystal oscillator then generates the desired frequency, which is outputted as an analog waveform.

The SIT9005ACB1H-XXDB also features an on-chip charge pump that generates reference voltages to/from which it can regulate the output frequency. This allows the user to program the oscillator to a desired frequency within a range of +/-500ppm, using a highly precise and reliable feedback loop between the DAC and the quartz crystal oscillator.

The SIT9005ACB1H-XXDB is a versatile and reliable oscillator that is suitable for a wide array of applications requiring frequency control. Its multiple output configuration and low power consumption make it an ideal choice for applications that require precise and reliable frequency control. Furthermore, its DDS-based system ensures stability and accuracy, making it the perfect choice for a range of frequency control applications.
