The CDC2509CPWR Clock/Timing generator is a high-performance monolithic device that offers a comprehensive array of integrated features to increase system performance, reduce system cost and save on board space. It is ideally suited for a wide range of Clock/Timing applications such as time synchronization, clock signal distribution, and jitter cleaning.

The CDC2509CPWR was designed to be compatible with telecommunications, computing, and industrial control applications. It is built on a high-speed BiCMOS process that allows it to operate with a wide range of frequencies, including those above 500MHz. The device supports four different output configurations, including synchronous and asynchronous outputs, as well as a spread spectrum output.

The CDC2509CPWR utilizes an all-digital Phase-Locked Loop (PLL) and Frequency Synthesizer, which are core components of many high-performance clock/timing systems. The PLL provides frequency locking and jitter attenuation, while the frequency synthesizer provides a wide range of output frequency configurations. The CDC2509CPWR features a low-power architecture and extensive clock control features, and is capable of handing multiple output clock signals with only a single device.

The device has an on-board oscillator designed for stable operation over a wide temperature range. This oscillator is used to generate a reference clock signal, which is then locked using a digital-controlled divider. The PLL and frequency synthesizer circuits then generate the required clock signal with the desired frequency, phase, and jitter performance.

The CDC2509CPWR offers an extensive clock control interface, allowing designers to set the clock frequency, phase, duty cycle, and slew-rate. It also supports multiple output formats such as differential LVPECL, HCSL, and LVDS, as well as single-ended outputs. The device provides a wide range of clock outputs and selectable output drive strength.

The CDC2509CPWR has an integrated jitter cleaning filter, which can be used to attenuate random jitter components and improve overall jitter performance. The device also features a clock monitor circuit, which can be used to detect clock stop or oscillation during system operation. Additionally, the device has an integrated fan-out buffer, allowing multiple devices to be cascaded for applications requiring multiple outputs or larger fan-out.

Overall, the CDC2509CPWR is an extremely versatile and reliable clock/timing generator. It offers a wide range of features, such as jitter cleaning, frequency synthesis, multiple output formats, and clock control, all in a single device. This makes it an ideal solution for applications requiring high-quality and reliable clock/timing signals.
