Introduction

Oscillators can be used as the clock source of a microcomputer system. They maintain a fixed frequency of oscillation, regardless of temperature, voltage and component variations. They are available in both digital and analog formats.Analog oscillators are made up of three main components: an amplifier, a tank circuit and a feedback loop. The amplifier converts the low-level signals from the tank circuit into high-level ones. The amplified signal is passed through the feedback loop which ensures that it oscillates at the desired frequency.SIT1602BC-32-28S-25.000625T is a type of analog oscillator, it has the characteristics of small size, low power consumption, low jitter, high precision, high stability and wide frequency range.

Working Principle of SIT1602BC-32-28S-25.000625T Oscillators

The working principle of SIT1602BC-32-28S-25.000625T oscillator can be broken down into three basic components: amplifier, feedback circuit and tank circuit.The tank circuit is composed of inductors and capacitors. It has two stages. In the first stage, the physical structure of the circuit is such that the two inductors and capacitors are coupled together. This forms a resonant circuit that is able to store and release energy periodically.The amplifier is responsible for amplifying the low-level signal coming from the tank circuit, so that the output can be high enough to drive the feedback circuit. The feedback circuit is composed of two components: a loop network and a feedback capacitor. This loop network is responsible for maintaining the oscillation frequency at the desired level.The output of the oscillator is the alternating voltage that is generated by the feedback circuit. This alternating voltage is then used to drive different components in the circuit.

Conclusion

SIT1602BC-32-28S-25.000625T is an analog oscillator. It is mainly used in communication, FPGA, SoC, microcontroller and other occasions. Its main features are small size, low power consumption, low jitter, high precision, high stability and wide frequency range. It works by amplifying the low-level signal coming from the tank circuit and passing it through a feedback circuit to maintain the oscillation frequency.
