Programmable oscillators are electronic components that are used to generate a signal of predetermined frequency and accuracy. They often contain an integrated circuit and two or more frequency-selective electronic components. In this article, I will discuss the application field and working principle of the SIT9005ACL1D-18DG Programmable Oscillator.

The application field of the SIT9005ACL1D-18DG Programmable Oscillator is quite broad. It can be used in a variety of electronics applications, such as medical equipment, automotive systems, communication systems, networking, and more. It is also a popular choice for embedded systems, such as embedded microcontrollers, because of its high level of precision and accuracy. The oscillator can also be used in high frequency mixed-signal designs, such as LCD displays and embedded high-speed communications networks.

The working principle of the SIT9005ACL1D-18DG Programmable Oscillator is quite simple. It utilizes the phase-locked loop (PLL) principle to generate a stable and accurate output frequency. The PLL consists of an oscillator, a phase detector, a loop filter, and a voltage-controlled oscillator (VCO). The oscillator creates an output signal of a predetermined frequency, which is usually determined by an external clock. The phase detector compares the output signal of the oscillator to an incoming reference signal and generates a control signal based on the differences. The loop filter processes the control signal to limit the correlation between the control input voltage and the oscillator output frequency. The VCO then takes the filtered output of the loop filter and produces the oscillator output.

The SIT9005ACL1D-18DG Programmable Oscillator uses a variety of features to ensure accurate and reliable performance. It has a wide operating temperature range of -40°C to +85°C and is compliant with the RoHS standard. It has a low power consumption of 18mW, with a low power mode of 2mW. It is also designed with a low phase noise of -90dBc/Hz at 1MHz and an operating frequency range of 400KHz to 10GHz.

The SIT9005ACL1D-18DG Programmable Oscillator is also designed with an integrated bus interface for digital programming. This allows for the quick and easy programming of the frequency and accuracy parameters, with a typical setup time of under 2 microseconds. Additionally, it has a wide range of configuration options and support functions available, including clock synchronization, pull-in mode, and a voltage-controlled input.
