Programmable Oscillators

Programmable oscillators are specialized components used in the production of radio-frequency signals, often seen in wireless communication and navigation systems, as well as scientific instruments and test equipment. One attribute of programmable oscillators which sets them apart from other oscillators is the ability to modify their operating frequency and/or phase using an external control input such as an analog voltage or a digital address bus. This allows the user to make fine-tune adjustments to the operating frequency, extend the dynamic range of these oscillators, and improve the overall performance of their systems.One type of programmable oscillators is the SIT9005ACE1D-28SO, designed to provide accurate and consistent frequency regulation in wireless communication and navigation systems. It utilizes a PLL (phase-locked loop) circuit that works by feedback-defined control of its various component components, including a voltage-controlled-oscillator (VCO) and digital frequency synthesizers. The input frequency is pre-programmed with a processor device, usually a DIP switch, so that it seamlessly integrates with the specific application requirements.The main advantages of the SIT9005ACE1D-28SO are its accuracy and stability. Its 15-bit divider and 32-bit accumulator ensure an impressive frequency resolution and excellent long-term stability; meaning minimal drift or deviation when the oscillator is exposion to environment fluctuations or power supply modifications. Its output frequency range can also be extended to cover a wide variety of different applications which require tuning with minimal disturbance to their performance.These oscillators are well-suited for navigating and surveying systems, such as base station broadcast tracking systems and automated weather stations, as well as telecommunication, medical, and instrumentation applications. In addition, it \'s compatible with the majority of commercially available microcontrollers and processors, allowing it to easily be incorporated into existing systems.Another good feature of the SIT9005ACE1D-28SO is its low power consumption as it has a sleep current of just 3μA and a single cycle locking time of just 500μs. The robust design of the oscillator also makes it reliable, with little to no maintenance required, and a warranty of up to 5 years on certain models.Overall, the SIT9005ACE1D-28SO programmable oscillator is a cost-effective solution for the long-term, reliable operation of wireless communication and navigation systems, telecommunications, medical, and instrumentation applications. As a result, it can be relied on to create a safe and consistent working environment, helping to limit personnel risk and improve overall efficiency.
