406I35E19M66080 Working Principle

The 406I35E19M66080 is an OCXO, which uses an active temperature stabilization method to maintain frequency accuracy. In this type of crystal, the temperature of the oscillator is monitored using a thermistor. A control circuit, also known as an oven control loop, monitors and controls the oscillator temperature to keep it stable, thus maintaining its frequency output.

The oven control loop compares the oscillator temperature to a reference temperature and sends a signal to a heater in the oscillator housing. This heater raises or lowers the oscillator temperature to maintain the set temperature. The loop continues to monitor and adjust the oscillator temperature until it reaches the desired temperature.

The OCXO also utilizes a series of passive components, such as capacitors, resistors, and inductors, to form a complete temperature compensated oscillator network. This network ensures that the frequency output remains accurate, even in temperature variations.

Conclusion

The 406I35E19M66080 is an oven-controlled crystal oscillator used in a wide variety of applications requiring high accuracy and precision. Its active temperature compensation system keeps the oscillator stable and accurate in temperature variations, while the passive components form a complete temperature compensation oscillator network. This makes the 406I35E19M66080 an excellent choice for many frequency applications.
