MPC9773AE is a state-of-the-art clock and timing device that integrates a Multi-Phase Clock Generator (MPC) and a synthesized, wide-range oscillator for all clock management needs. The MPC9773AE offers the highest level of performance and flexibility, enabling designers to efficiently manage the clock quality, power and cost trade-offs in their designs, with one device.

Application Field

The MPC9773AE is designed for a wide range of applications, including personal computers, workstations, network routers, storage-area networks and embedded systems. All types of designs, from low-cost and low-power systems to high-end and highly demanding applications, can benefit from the wide-range, multiple-output device. It is versatile, thanks to its integrated clock generator and synthesized oscillator, making it ideal for a variety of platforms, including general-purpose, multimedia, communication and mobile.

Working Principle

The architecture that enables the MPC9773AE’s highly capable clock management consists of a single-phase clock generator and a synthesized, wide-range oscillator. The clock generator produces two sets of multiple-phase, multiple-output (MPC) clocks, which provide designers with the flexibility to manage multiple clock domains and accurately synchronize their operation.The MPC9773AE also features the advanced, low-noise synthesized oscillator, which is well suited for generating the reference clock for multiple CPUs, system buses and other system clocks. The device’s wide-frequency range allows for generating high-frequency clocks, such as those needed for High-Speed I/O and 100Base-T applications, from a single crystal. The combination of the clock generator and oscillator enables a single device to provide multiple system clocks in one package.

The MPC9773AE features Clock Pruning Technology (CPT), which enables it to shrink the amount of chip real estate occupied by clock components, while maintaining excellent clock accuracy. CPT gives the device the flexibility needed to quickly accommodate any changes in the system clock requirements during the design cycle. In addition, the MPC9773AE offers two levels of programmable skew, allowing designers to control how quickly clocks transition and ensuring the highest level of clock synchronization possible, even across a wide range of temperatures.

The MPC9773AE also includes all relevant timing features, such as programmable duty cycles, clock enable, clock inhibit and asynchronous reset capability for all the output clocks, and it is di system power modes, including a low-power shutdown mode. In addition, asynchronous reset enables the device to recover from any power failure without disrupting the associated system. The integrated, wide-range oscillator also provides exceptional jitter performance, designed to meet the industry’s most demanding performance criteria.

In summary, the MPC9773AE is a complete, highly capable clock and timing solution for a variety of applications, offering unsurpassed flexibility, performance and power savings. Its integration of the MPC clock generator and the wide-range low-noise synthesized oscillator, paired with the Clock Pruning and programmable skew features, provide a cost-effective and reliable solution that can quickly adapt to changing system requirements.
