Working principle

The SIT1602BC-83-30S-66.666660T oscillator is a monolithic oscillator based on a globally-available Si2100 temperature-compensated crystal oscillator (TCXO). It operates at a fixed frequency set by a quartz crystal. The output frequency of the oscillator is determined by the characteristics of the quartz crystal, the drive level applied to it, and the temperature.

The oscillator consists of a quartz crystal with a crystal oscillator circuit connected to it. The oscillator circuit typically consists of an amplifier, feedback circuit, and frequency-determining components. The amplifier is driven by an external signal, such as a voltage or current, and the feedback circuit feeds back the output signal to the amplifier. As the amplifier amplifies the signal, the frequency of the output signal increases. The frequency-determining components control the amount of feedback and the amplified signal level on the output, thereby controlling the output frequency.

The oscillator is temperature-compensated by a temperature sensor connected to the circuit. The temperature sensor monitors the temperature of the oscillator, and adjusts the oscillator\'s frequency to compensate for temperature variations. This ensures that the output frequency remains stable and accurate over a wide temperature range.

The SIT1602BC-83-30S-66.666660T oscillator operates at a frequency of 66.66666 MHz and is available in a range of packages. It has excellent stability and accuracy over a wide temperature range, making it ideal for applications where clock stability and accuracy is required.
