SIT9121AC-2DF-33E200.000000T is also suitable for ultra-reliable EMC demanding systems that have requirements on noise suppression such as in professional audio systems.

The working principle of SIT9121AC-2DF-33E200.000000T is based on the relaxation oscillator circuit, where a variable resistor is connected to a quartz crystal as a tank circuit. When the power is on, the resistor charges the capacitor and keeps charging until the voltage reaches a certain level at which point the capacitor gets instantly discharged. This generates a square wave output with a specific frequency. The resistor adjusts the speed of the discharge and thus determines the output frequency.

The oscillator has a high output power level of 160mW. It has a low average frequency stability of ±10ppm over a temperature range of -10°C to +60°C, with a maximum startup time of 10ms. The oscillator is also equipped with short circuits and overvoltage protection, as well as with a pullability of ±50ppm. In addition, SIT9121AC-2DF-33E200.000000T also offers excellent thermal stability. It is designed for operations from -5°C to +50°C, with a power variation of less than ±5ppm.

In conclusion, SIT9121AC-2DF-33E200.000000T provides a reliable source of precision frequency with outstanding features for a wide range of applications. It offers excellent performance and reliability as well as excellent thermal stability and high average frequency stability.
