Oscillators play a vital role in the successful functioning of signal processing systems. With a wide range of applications and a number of designs available, these circuits have been adapted to fulfill modern engineering needs. The SIT9120AI-1C1-33S106.250000Y oscillators are designed to provide low-jitter performance, high frequency stability and temperature compensation which makes them ideal for embedded applications like Telecom, Automotive, Aerospace, and Robotic Modules.

The SIT9120AI-1C1-33S106.250000Y oscillators integrate a fixed frequency quartz crystal and a reliable PLL (Phase-Locked Loop) circuit based on CMOS logic to ensure superior timing performance with low maximum jitter. The output frequency of the clock signal is derived from a reference input frequency that is divided down inside the PLL. The reference frequency is further divided by two different dividers, the first divides by N, comprising an integer multiplied by a linear feedback shift register output for a low frequency clock output, while the second divider divides by M, resulting in a relatively higher reference frequency.

The dividers are adjusted to obtain the desired output frequency resolution. PLLs are used to manage multiple digital signals in real-time, enabling symmetric communication and synchronization across multiple digital components. Therefore, these oscillators are suitable for numerous embedded applications such as digital audio systems, RF transmission systems, multimedia applications, embedded systems, video streaming systems, etc.

The SIT9120AI-1C1-33S106.250000Y oscillators feature an output signal frequency of 106.250000 MHz+/-50ppm. They will operate at -40°C to +85°C and come with an ultra-low jitter performance of 0.2 ps maximum at 156.25MHz. The oscillator is RoHS compliant, and features charging pump circuits to reduce the power consumption levels. It also includes an off-chip LC network that can be used to reduce the output frequency spread.

In conclusion, the SIT9120AI-1C1-33S106.250000Y oscillators are designed to offer reliable and stable performance with high frequency accuracy and low jitter which make them ideal for embedded applications like Telecom, Automotive, Aerospace, and Robotic Modules. They are built on a PLL structure, and utilize two dividers for increased signal resolution, along with a number of other features that make them viable in real-time and demanding applications.
