The AD9522-5BCPZ is a clock generator, phase locked loop (PLL), and frequency synthesizer designed specifically to provide the benefits of increased system efficiency and minimized clock jitter. The AD9522-5BCPZ provides low input and output clock jitter and integrates many features, such as spread spectrum clocking (SSC) and flexible output skew, that are required for modern microprocessor-based systems.

The AD9522-5BCPZ achieves its low input and output jitter performance through a combination of its PLL and frequency synthesis circuitry. Specifically, the PLL locks the input clock to a reference clock and then the frequency synthesis circuitry generates the required output clocks from the reference clock. The center frequency of the PLL can be adjusted to match that of the input clock and the frequency synthesis circuitry can generate the required frequency shift. This allows for the synthesis of frequencies that are different from the reference clock frequency.

The AD9522-5BCPZ also features many features that provide enhanced design flexibility and improved system efficiency. The PLL can be configured to accept an external reference clock, allowing the system to operate without the need for an on-board clock source. This reduces system complexity and cost. The AD9522-5BCPZ also features spread spectrum clocking (SSC), which reduces peak-to-peak input jitter, providing improved system performance and reliability. In addition, the device offers flexible output skew control, allowing designers to optimize the skew between clock outputs to meet system requirements.

The AD9522-5BCPZ is designed for applications that require low jitter clocks and frequency synthesis, including microprocessor-based systems, storage systems, communication systems, consumer electronics, computer peripherals, and system-on-chip (SoC) designs. The AD9522-5BCPZ provides a simple, cost-effective, and reliable solution for generating low jitter clocks and frequency synthesis.
