Application Fields

The AX7PBF3-725.0000T is designed to provide low-cost and reliable clocking solutions in a wide range of applications. It is particularly well suited to use in communications systems, such as mobile phones and base station equipment. The low jitter of the AX7PBF3-725.0000T and its wide operational temperature range make it an ideal choice for high-performance clocking requirements in those applications.

In addition, its low power consumption makes it ideal for use in portable devices and other battery-operated equipment. Its digital-controlled frequency range makes it suitable for image processing, radar and medical imaging applications, as well as a variety of data transfer and sampling applications.

Working Principle

The AX7PBF3-725.0000T employs a digitally-controlled oscillator (DCO) architecture based on a PLL-based frequency synthesizer. The DCO contains a programmable frequency synthesizer that uses a fractional-N frequency divider and a voltage-controlled oscillator (VCO) to generate accurate output frequencies. The output of the VCO is divided by a programmable divider to produce the desired output frequency.

The output frequency is controlled by the analog voltage applied to the input of the VCO. This voltage is generated by an on-chip digital-to-analog converter (DAC). The DAC is controlled by a digital programming interface, which allows the user to select one of 16 pre-defined frequencies or to program a custom frequency.

The AX7PBF3-725.0000T includes an on-board temperature compensated voltage regulator, which ensures a stable supply voltage and temperature compensation of the frequency output. This ensures stable operation over a wide temperature range, without the need for external components.

Conclusion

The AX7PBF3-725.0000T is a low-cost, digitally controlled oscillator from Abracon Corporation. It is designed to provide reliable clocking solutions for communications systems, image processing, radar and medical imaging applications. It employs a PLL-based frequency synthesizer architecture that allows for a wide range of frequency outputs and low jitter performance. In addition, its low power consumption and temperature compensated voltage regulator make it an ideal choice for portable and battery-operated equipment.
