AD9530BCPZ is a high-performance and low-cost, low-power CMOS clock and frequency synthesizer for use in general timing applications in communications, data processing and networking systems.

The device allows for independent control of a programmable reference oscillator, phase detector, and fractional-N frequency synthesizer in order to provide multiple channels of stable, low-jitter clock output frequencies. It is the most cost-effective device in the AD9530 family with a simpler design, lower power consumption, and less stringent requirements on the reference oscillator.

Application Field of AD9530BCPZ

AD9530BCPZ is most suitable for applications with limited oscillator power, such as communications and networking systems, infrastructures, consumer electronic devices, automotive, and avionics. It can be used as a clock/timing solution for network edge signaling, featuring low-frequency jitter for high-speed implementation of new standards.

The AD9530BCPZ provides superior jitter performance over the broader range of frequencies, which is critical for the reliable operation of multiple communications and networking systems. It also provides flexibility in terms of its ability to support multiple output configurations.

Working Principle of AD9530BCPZ

The working principle of the AD9530BCPZ is based on an advanced differential charge pump-based design. The charge pump generates a voltage-controlled oscillator (VCO) clock output by linearly adjusting the VCO frequency over time according to the charge pump’s voltage control input. This process is called slew rate control.

The AD9530BCPZ contains a reference oscillator that produces a programmable output clock frequency. The reference oscillator frequency is then divided down by an internal divider stage and used to compare against an external clock frequency in a phase/frequency detector, which drives the charge pump.

The output of the charge pump is then fed into a low-noise VCO. The VCO frequency can be adjusted by the charge pump or by an external voltage source to achieve the desired output frequency. The VCO output frequency is then divided down to the desired output frequency by an internal divider stage and sent to the output pins.

The AD9530BCPZ provides a variety of features that make it simple to configure and use in a variety of applications. For example, it is capable of driving up to four clock/timing outputs with up to four separate CMOS levels or can be used as a jitter cleaner. Additionally, it offers a wide range of programmable parameters including phase shift, frequency division and input clock frequency selection.

The AD9530BCPZ is an ideal solution for customers needing to generate multiple clock/timing signals with high performance, low jitter, and low cost. The device supports a wide range of programmable parameters, making it a highly flexible and versatile solution that can be used in a variety of applications.
