The CDCE949PWR is a 1-to-6 frequency generator, also referred to as a low-jitter programmable clock synthesizer. It can generate 1-6 output frequencies, with each output frequency as high as 250 MHz. The CDCE949PWR also includes an internal 14-bit phase accumulator, providing precise phase control over one or multiple output frequencies. In addition, the part offers considerable flexibility to users with the ability to program multiple phase values and frequencies within a single register.

The CDCE949PWR is commonly used in applications requiring high-frequency, low-jitter output signals, such as platforms and devices related to communications, broadcast, audio-video equipment and defense. The part is also ideal for applications which require multiple clock and data signals, such as digital signal processing, baseband, wireless and Ethernet applications.

The working principle of the CDCE949PWR is that the M/N divider is used to divide the input frequency into multiple prescaler outputs, and the resulting signals are then combined to form the required output clock frequency. For each output, a pair of M/N dividers is used, with the M/N ratio defining the frequency of the output. The phase alignment between the resulting signals is then obtained by using a cascade of multiplexers and changeover switches. This allows all the outputs to be synchronized with each other, even if the frequency and phase of each output is distinct.

The CDCE949PWR can be programmed to generate 1 to 6 unique clock outputs, and allows each output to be synchronized. Furthermore, the part includes an on-chip phase offset register, which enables phase shifting between the outputs, allowing each output to be accurately aligned in time. Moreover, the part has an integrated loop-filter which ensures that all outputs are both phase and frequency stable. Lastly, a low power consumption of 250mW (typical) allows the CDCE949PWR to be deployed in extended operating temperature environments.

Overall, the CDCE949PWR is a highly flexible and low-jitter programmable clock synthesizer, designed to generate 1-6 frequencies with a maximum frequency of 250MHz. The part is suited for use in systems requiring precise timing, such as digital signal processing, baseband, wireless and Ethernet applications. The on-chip phase offset register and loop-filter ensure that all outputs are both phase and frequency stable, while the integrated low power consumption allows the part to be used in extended operating temperature environments.
