The working principle of the 550AF644M531DG depends on the operation of the integrated circuit. The device consists of two groups of transistors – one responsible for the clock signal generation, while the other to provide the power for the circuit. The first group of transistors is R2 and R3, which are in charge of conducting the current for the signal produced by the second group of transistors Q1 and Q2. This output of the second group of transistors, which is a sine-wave signal, is then sent to the output pin of the device.

When the power is connected to the device, the power supply voltage connects to the VCC pin, and a voltage drop is created between the two transistors of the first group. This voltage drop is sensed, and then it is rectified by the second group of transistors. This rectified signal is then sent to the output pin and this output is the final sine-wave signal.

The 550AF644M531DG has proved to be an effective and reliable oscillator when used for the generation of sine-wave signals. Its wide range of frequencies and small footprint, combined with its low power consumption and excellent temperature range make it an ideal choice for many different applications.
