Introduction to Oscillators

An oscillator is an electronic circuit that can generate a continuous waveform whose frequency can be adjusted. Oscillators are widely used in electronics as timers and in radio transmission as transmitters. The output of an oscillator can be used to control the frequency or phase of a signal or to create a tone signal. Oscillators are also used in a variety of other applications, such as in clocks, watches, and alarms.

SIT8208AC-21-28S-16.367667Y Working Principle

The schematic diagram of SIT8208AC-21-28S-16.367667Y oscillator is shown below.

The working principle of this oscillator can be explained in the following steps:

1. The clock signal is generated by the quartz crystal oscillator (QCO) and is amplified by a bipolar operational amplifier (op-amp) before being routed to the clock input of the inverter.

2. The output of the QCO is also used to control the voltage of a voltage regulator, which supplies a regulated voltage to the oscillator.

3. The signal from the inverter is then passed through a buffer amplifier before being routed to the oscillator\'s output.

4. The output of the oscillator is an electrical signal that has a precise frequency determined by the resonant frequency of the crystal. The frequency can be adjusted by varying the supply voltage.
