Programmable oscillators, such as the SIT3821AI-2B-33NY, are a type of oscillator which is designed to allow a user to program a desired frequency and other characteristics of the oscillation. These devices are typically used in a variety of applications, including audio and video encoding, communication systems, and clocking of digital processing systems.The SIT3821AI-2B-33NY is a programmable oscillator that offers a wide range of frequency and stability options. It is capable of generating frequencies between 10KHz and 80MHz, and it can accept input frequencies from various external clock sources. The device is also capable of outputting both a 250MHz output signal and a 400MHz phase-frequency detector (PFD) signal. Additionally, the SIT3821AI-2B-33NY has a phase jitter of less than 30ps RMS which makes it useful for applications requiring precise timing.

The working principle of programmable oscillators is based on the use of mixers to mix the frequency from an external source with internally generated frequencies. The devices typically use three or four frequency mixing stages, each stage being set to a different frequency. The external source is used as a reference signal, with the internally generated frequencies being used to modulate the signal. The signal is then fed into a filtering stage where it is filtered to remove unwanted frequencies. The signal is then output from the oscillator at the desired frequency.
