Oscillators are integral components of almost all electronic circuits. They provide a means to generate a periodic signal, allowing the circuit to be synchronized with the outside world. One such oscillator is the LFTVXO009917BULK, which can be used to generate precise clock signals for CPU systems as well as producing high accuracy time-base signals for communications applications. In this article, we will look at the application field and working principle of the LFTVXO009917BULK.

Application Field

The LFTVXO009917BULK is a highly stable oven-controlled oscillator (OCXO) designed for use in applications that require a reliable and accurate reference frequency. The oscillator is suitable for precision voltage-controlled crystal oscillator (VCXO) applications, as well as for ultra-precise frequency standard applications, such as providing a reference frequency for telecommunications systems, digital audio systems, instrumentation, and GPS systems. It is also suitable for use in military, industrial, medical, and aerospace applications.

The oscillator is available in a range of frequencies, including 10MHz, 20MHz, and 40MHz, and with different temperature stabilities. The temperature stabilities vary from ±2.5 x 10-9 to ±1 x 10-10. The LFTVXO009917BULK is available in a variety of package designs, such as DIP, LGA, SMD, and ceramic packages.

Working Principle

The LFTVXO009917BULK is based on a basic bulk acoustic wave (BAW) oscillator architecture. The oscillator consists of a quartz crystal, an amplifier, and an oven for temperature stabilization. The quartz crystal is mounted between two electrodes, known as the ‘exitation’ and ‘ground’ electrodes. The quartz crystal is then electrically excited at its natural frequency, which causes it to oscillate. The output of the crystal is then amplified in the amplifier and fed to the oven. The oven maintains the temperature of the oscillator, allowing it to operate at a very precise frequency.

The overall accuracy of the oscillator is determined by the stability of the quartz crystal and the temperature-stability of the oven. The high temperature stability of the oven ensures that the oscillator can maintain a very precise frequency without any significant frequency drift. The low temperature-stability of the quartz crystal ensures that the oscillator does not experience any phase noise or jitter.

Conclusion

The LFTVXO009917BULK is an excellent choice for applications that require a reliable and accurate reference frequency. It is well suited for applications such as providing a reference frequency for telecommunications systems, digital audio systems, instrumentation, and GPS systems. The oscillator is accurate and highly stable, allowing it to generate precise clock signals and maintain high accuracy time-base signals.
