MPC9774AE is a high-performance integrated clock generator and frequency synthesizer. This device offers many features which make it ideal for a broad range of applications from communications to industrial and automotive. The architecture of the device utilizes a single crystal oscillator with a phase-locked loop (PLL) and digital logic to generate a wide range of frequencies, ranging from 10 to 2800 MHz. This enables applications to use fewer components and cost effectively address many timing needs.

Application Field

MPC9774AE clock generators are used in a variety of industries including 5G communications, consumer electronics, medical devices, automotive, industrial, aerospace, and defense. The various clocking solutions enable OEMs to quickly and efficiently produce a wide range of custom solutions without the expensive design time associated with custom-made or discrete components. The MPC9774AE universal clock generator is an ideal solution for applications requiring an accurate and stable clock signal with a broad range of support frequencies.

Working Principle

The MPC9774AE clock generator and frequency synthesizer utilizes a dedicated clock generator core, a phase-locked loop (PLL), and digital logic to generate a wide range of frequencies, ranging from 10 to 2800 MHz. This unique architecture provides very low jitter, fast amplitude settling time, and high accuracy. A dedicated control interface allows for direct access to the PLL and clock generator for configuration and optimization.

The PLL section consists of a low-noise, low-phase-noise frequency synthesizer and pre-programmed, predefined timing solutions. The clock generator section consists of an A/D converter, dual phase-domain filter, and digital filter. The combination of these components allows for very fast lock-time and superior accuracy.

The device also features clock selection logic and an on-chip active crystal oscillator that allow for harmonic lock. This feature allows the device to lock onto any harmonic of the crystal which provides improved jitter performance and fast settling time. The device also offers advanced start-up and shutdown techniques which ensure fast and accurate operation at power-on and power-off conditions.

The device supports a broad range of output clock solutions and power budgets and is capable of providing up to 10 different outputs. It also includes three separate clock output steering signals and a dedicated pulse-peak-detect (PPD) signal which provides direct access to the PLL output. These features enable the device to easily be incorporated into a wide range of different applications.

Conclusion

MPC9774AE is an ideal choice for many applications in the communications, consumer electronics, medical devices, automotive, industrial, aerospace and defense industries. With its low jitter, fast amplitude settling time, and high accuracy it is a powerful solution for clock and timing system development. The wide range of available output frequencies and support for three independent clock outputs make this device a great choice for applications which demand high performance and flexibility.
