In addition, the 637L50B6C3T oscillators are suitable for the highest precision industrial frequency control and timing applications in industrial controllers and process equipment.

Working Principle

To generate the desired output frequency, the 637L50B6C3T oscillator works by using a multiply cycle oscillator (or step oscillator) to divide a reference frequency with a precision divider. This divided output is then amplified by a voltage controlled amplifier (VCA) and the output of the VCA is fed back to the input of the divider. The feedback loop of the divider and amplifier maintains a stable output frequency. The VCA is controlled by the input voltage and can be used to charge or discharge the crystal oscillator, thus adjusting the frequency of the oscillator.

The 637L50B6C3T oscillator also has an auxiliary control input which is an external voltage controlled input used to control the frequency of the oscillator. This can be used to set the frequency within a certain range, or to trim the frequency if needed. The oscillator also comes with an adjustable control range up to 200 parts per million, which is more than enough to cover a wide range of applications.

Conclusion

The 637L50B6C3T oscillator is an ideal choice for precision frequency control and timing applications. Its wide frequency range makes it suitable for use in a variety of applications including radio and television equipment, audio and video processing equipments, industrial systems, automotive electronics, medical and laboratory equipment, and cosmetology machines.
