Oscillators

Oscillators are components which generate oscillatory electrical signals at a frequency determined by the components´ circuitry. Oscillations can be any regular, and repetitive, electronic signal, such as a sinusoid, square wave, or sawtooth wave. Oscillators can be used in a wide range of applications ranging from controlling the speed of motors to generating radio waves for transmission of signals. One type of oscillator is the SIT1602BC-81-25S-37.500000T.

Application Field

The SIT1602BC-81-25S-37.500000T is a synthesized TCXO (temperature-compensated crystal oscillator). It is designed for a wide range of applications such as GPS transmitter synchronization, Bluetooth™ communication, large-scale servers, personal computers, and other general purpose applications. It has excellent accuracy (at 1 ms/day) and stability (at 0.5PPM), making it suitable for precision systems that require high-performance oscillation control.

Working Principle

The SIT1602BC-81-25S-37.500000T is a temperature-compensated oscillator, meaning that it uses a crystal oscillator to provide an oscillation signal, and utilizes a temperature compensation circuit to keep the oscillation frequency stable. This is achieved by using an oscillator temperature sensor, also known as a frequency controlled oscillator (FCO), to detect the ambient temperature. This FCO then output an analog voltage which is used to compensate the frequency of the TCXO in order to keep it stable over a wide temperature range.

Furthermore, the SIT1602BC-81-25S-37.500000T uses a precision trimming technique to minimize the difference between the desired and actual frequency of the oscillator. This is done by using trimmer resistors to adjust the frequency output of the oscillator. The trimmer resistors are adjusted to compensate for any environmental factors that affect the oscillator’s frequency, such as temperature, pressure, and humidity. This ensures that the oscillator maintains its accuracy and stability under varying environmental conditions.

Conclusion

The SIT1602BC-81-25S-37.500000T is an example of an advanced temperature-compensated oscillator which is designed to operate over a wide range of temperatures and environmental conditions. It utilizes temperature compensation to ensure accuracy and stability, and its precision trimming technique minimizes the difference between the desired and actual frequency. Therefore, it is suitable for a wide range of applications that require high-performance oscillation control.
