AX7DAF2-500.0000T

Oscillators

Oscillators are components that produce continuous output signals, usually sine or square waves, with a certain frequency. Oscillating circuits are generally constructed with an amplifier powered by a voltage source, an energy-storing device (capacitor or inductor) that determines the period of oscillation, and a feedback network that allows the amplifier to control the output level and the frequency. Oscillators are used to create waveforms that can be used to control motors, test circuits, time systems, or provide other functions in an electronic system.

AX7DAF2-500.0000T is a High-Performance, low-cost oscillator with excellent frequency stability. It has an internal AX7 ceramic resonator element to provide a stable frequency output with frequency tolerance to ±0.5ppm. The output frequency of the device is specified by the user and can be programmed with an external resistor.

The device has a wide operational temperature range of -40°C to +85°C with additional optional extended temperature range of -55°C to +125°C. It also has a low current consumption of 4 mA typical at 5 VDC. Because of its small size and low power requirement, AX7DAF2-500.0000T is suitable for battery operated applications.

The device supports a wide frequency range from 0.5kHz to 77MHz in 250kHz steps, and the user can select the output frequency by setting two external resistor values. It also is equipped with a power supply rejection rate of 125dB, and it is highly immune to noise interference and other external noise sources.

The working principle of the AX7DAF2-500.0000T is based on a voltage controlled oscillator circuit. When a voltage is applied to the AX7 ceramic resonator element, it changes its capacitance and, therefore, its frequency. By varying the voltage applied to the resonator, its frequency can be changed. This principle is implemented in the AX7DAF2-500.0000T to allow the user to set its frequency through an external resistor. The device has an I/O logic pin which allows the user to adjust the output frequency through a logic signal applied to the pin.

The AX7DAF2-500.0000T is a highly stable, cost-effective oscillator which can be used for various applications such as communication base station, test and measurement equipment, medical equipment, and automotive applications. It is designed to meet EMC, environmental, and electrical performance requirements. It is also suitable for use in harsh operating environments.
