Oscillators have a unique set of characteristics that offer various capabilities and applications. These include but are not limited to powering electronic circuits, providing timing signals, signal stabilization, and frequency measurement. The AX7PBF1-491.5200T is a versatile oscillator that primely serves as a voltage-controlled crystal oscillator (VCXO) and is an excellent choice for powering critical circuits in common applications.

The AX7PBF1-491.5200T is a high performance oscillator with a frequency range of 4.91 kHz to 5.2 MHz, an output voltage of 3.3V, a start-up time of 4.6ms, and rise and fall times of 5ns and 3ns respectively. It features adjustable frequency stability from ± 25.0 ppm to ± 100.0 ppm via a voltage range of 0 volts to the maximum operating voltage. It is also equipped with a supply current of 11 mA, an input voltage of 1.8V, and a maximum supply voltage of 5.0V.

AX7PBF1-491.5200T is based on a quartz crystal resonator circuit and is used in applications that require precise frequency control such as telecommunications, television and radio transmitters, ultrasonic and medical imaging equipment as well as GPS systems. The frequency can be adjusted based on the input voltage, which is generated from an output of a digital logic circuit. This makes it ideal for systems requiring communication between digital circuits and other devices.

The oscillator circuit consists of a quartz crystal, a capacitively loaded feedback resonant circuit and an active amplifier circuit. The resonant frequency of the quartz crystal is determined by piezoelectric effect, which is caused by applying an alternating current to the crystal. The frequency of the alternating current is then determined by the inherent frequency of the quartz crystal. The amplifier circuit amplifies the output frequency of the quartz crystal in order to provide the output waveforms.

The amplitude of the output waveforms is adjustable by varying the input voltage. The maximum output will be achieved when the voltage is highest and the minimum output will be achieved when the voltage is lowest. This adjustable feature enables the oscillator to be used in applications where a specific frequency is required to achieve various goals. As such, it is a useful tool for providing timing signals and signal stabilization.

In addition to adjustable frequency stability, the AX7PBF1-491.5200T also features a zero-disable function. This allows the power to be disabled when the input voltage is at 0 volts, which helps to reduce the power consumption of the oscillator. Furthermore, the oscillator features low phase noise and jitter, which make it suitable for applications that demand low phase noise performance.

The AX7PBF1-491.5200T is a robust oscillator that is suitable for applications that require precise frequency control. It is a versatile solution due to its adjustable frequency stability, low phase noise and jitter, and zero-disable function. It is therefore suitable for powering critical circuits in common applications such as telecommunications, television and radio transmitters, ultrasonic and medical imaging equipment as well as GPS systems.
