Oscillators

The PBF550006 oscillator is an integrated circuit designed to replace quartz crystal oscillators in many applications achieving an especially robust design. It integrates both the oscillators and the frequency control circuits, eliminating the requirements for any external components. This oscillator offers exceptional frequency stability and it is also tolerant of environmental changes such as variation in temperature.

Application Field

The PBF550006 oscillator is a highly versatile device that can be used in a wide range of applications. It offers superior reliability in applications requiring frequency stability, such as in radios, television, cellular phones, personal computers, servers, printers, automotive systems, automation, energy storage systems, medical equipment, and more. Furthermore, it can be used in applications requiring quick response and no mis-tune or mis-triggering, such as frequency synthesizers, communications protocols, frequency counters, and digital clock circuit.

Working Principle

The PBF550006 oscillator uses a quartz crystal resonator configured in a Pierce power oscillator circuit. The circuit is comprised of an active transistor, a passive circuit with a quartz crystal, and a feedback loop. The transistor, along with the passive circuit, creates a signal which is then amplified by the transistor via the feedback loop. This amplified signal is then outputted as the oscillator output.

The frequency of the oscillator is determined by the capacitance and conductance of the quartz crystal in the resonance circuit. By carefully controlling the values of these two parameters, the oscillator can be tuned to the desired frequency. Additionally, the frequency of the oscillator can be adjusted by simply adding a capacitor across the quartz crystal.

The PBF550006 oscillator is a robust oscillator and has excellent frequency stability. It is able to maintain its frequency range even when exposed to dynamic environmental conditions such as temperature and vibration. Furthermore, it has a high immunity to electromagnetic interference which makes it an ideal choice for many applications.
