Working Principle

The SIT3821AI-2D-33EB programmable oscillator works on the principle of resonance. The device consists of an oscillator section and a programmable resistor, which can be used to modify the frequency of the oscillator. The oscillator output can be frequency-modulated by either static external resistance or dynamic input voltage.

To begin with, a current is passed through a resistor, which is then tuned to a desired frequency. This variation in current results in a voltage across the resistor, which is fed back to the oscillator to control its output frequency.

The oscillator is then programmed by selecting a frequency, a phase shift and a duty cycle. The oscillator frequency can be adjusted over a wide range by changing the external resistor, allowing for accurate frequency control. The oscillator output is also tunable, with a wide range of frequencies available.

The SIT3821AI-2D-33EB programmable oscillator is designed to be used in systems with a wide voltage supply range, from 3.2V up to 5.5V. The oscillator works in a temperature range of -25°C to +85°C and is also RoHS compliant.
