MPC961PACR2 is an integrated multiloop clock generator solution designed for high-end system applications. It consists of three main components, a main clock synthesizer, a phase-locked loop (PLL) circuit and a frequency synthesizer. All components work together in unison to create a highly accurate clock signal that can be used in both digital and analog applications.

The main clock synthesizer generates a base clock frequency accuracy up to +/- 10 ppm. The PLL circuit further helps to compensate for temperature, voltage and part-to-part variations through frequency multiplying and phase shifting. Likewise, the frequency synthesizer assists in phase-locking the output clock frequency to that of a desired reference signal. Together, these components are capable of providing a single synthesized clock output at any frequency from different sources.

MPC961PACR2 can be used in a variety of applications, including high-speed clock generation for digital signal processors (DSPs), image sensors, cellular base station systems, as well as special purpose components such as frequency synthesizers and radio systems. In addition, its low jitter and low phase noise are essential for high-end RF applications such as WiFi, Bluetooth, WiMAX, and the IEEE 802.11 Standard.

In terms of its working principle, MPC961PACR2 utilizes a combination of phase-locked loop (PLL) and frequency synthesizer circuits to achieve a high level of accuracy and jitter performance. The PLL circuit works by transferring the phase information of the reference clock signal to the output clock signal, while still preserving its frequency characteristics. The frequency synthesizer further optimizes the output clock frequency by utilizing programmable loop filter parameters and phase-locked loop parameters to pull the output clock frequency closer to the desired reference clock signal.

MPC961PACR2’s unique features make it the ideal solution for high-end clock generation applications where tight control over accuracy, jitter and phase-noise are required. The integration of the two main components, a PLL circuit and a frequency synthesizer in to one chip, also make it a cost-efficient and reliable solution for any project.
