Oscillators are electronic circuits which convert a direct current into an alternating current signal with predetermined or adjustable frequency. The SIT1602BI-21-30S-32.768000E is one type of oscillator falling into this subject. This oscillator which is a low-power consumption, ultra-low-voltage oscillator, provides an output frequency accurate to ±20 ppm over 0 °C to 70 °C.

The SIT1602BI-21-30S-32.768000E has a wide range of application fields. Firstly, it can be used in wireless communication such as wireless local area networks (WLANs), Bluetooth, ZigBee, and ultra-wideband (UWB) applications. Secondly, it is widely used in devices needing precise timing signals, such as smart cards, palmtops, personal digital assistants, and watches. Additionally, it is used in set-top box, voice over internet protocol (VoIP) applications. In addition, it can also be used in medical applications like heart rate monitoring, wearable healthcare devices, home health care equipment, and blood pressure monitors.

The working principle of SIT1602BI-21-30S-32.768000E is mainly based on CMOS technology. Its internal oscillator generates the signal frequency through feedback loops and frequency division, where the loop forms a path that produces the output frequency of oscillation. It works similar to a transistor-based harmonic oscillator. The oscillator board is composed of an inductor, capacitor, resistor and a main switch, all of which are integrated into the oscillator. When power is applied to the circuit, the capacitor charges, resulting in a reaction between the capacitor and the inductor which, in turn, creates a resonance inside the oscillator. This resonance creates a strong feedback loop. The frequency of the oscillator is determine by the components used in the circuit, such as resistors, capacitors and inductors.

In summary, SIT1602BI-21-30S-32.768000E oscillator belongs to the oscillator family and is a low-power consumption, ultra-low-voltage oscillator. It has a wide range of application fields such as wireless communication, precise timing signals, set-top box, VoIP, medical applications etc. Its working principle is based on the CMOS technology and resonates inside the oscillator.
