Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The SI51218-A07980-GM is an integrated device designed for clock/timing applications. It is a multi-output clock generator ideal for ultra-low power applications, portable designs, and high-performance Network Interface Cards (NIC). This integrated product achieves the lowest power consumption and highest performance in the industry, making it an ideal choice for highly efficient designs.The SI51218-A07980-GM clock generator combines a phase-locked loop (PLL), a fractional-N frequency synthesizer, a spread-spectrum modulator, and a bank of selectable low jitter oscillators. With its comprehensive feature set, the SI51218-A07980-GM provides the flexibility needed to meet most clock/timing requirements.The SI51218-A07980-GM PLL can be used to generate a wide variety of frequencies up to 825 MHz, with 1.4 ps of jitter. The PLL also includes a spread-spectrum modulator, which can be used to reduce electromagnetic interference (EMI) from high frequency oscillators, as well as provide phase noise reduction. The PLL also provides output phase control up to 30 degrees to apply phase delays to specific output frequencies.The SI51218-A07980-GM can also be used as a fractional-N frequency synthesizer to generate frequencies that are precisely related to a stable reference frequency. This feature makes the SI51218-A07980-GM ideal for frequency synthesis applications, such as synthesizing a frequency divider to generate a precisely controlled clock or to generate a frequency that is not provided by an oscillator.The SI51218-A07980-GM also provides selectable low jitter oscillators with output frequencies ranging from 125MHz to 825MHz. The clock generator also provides a multi-layer configurability which allows designers to program the device with a variety of output configurations.The SI51218-A07980-GM is ideal for a wide range of clock/timing applications including data communications equipment, dense wireless networks, ultra-low power designs, digital television equipment, and mobile multimedia. By using the SI51218-A07980-GM, designers can achieve lower power consumption, higher performance, and more reliable clock/timing solutions than with traditional designs. In summary, the SI51218-A07980-GM is a multi-output clock generator that includes a comprehensive set of features for clock/timing applications. It combines a PLL, a fractional-N frequency synthesizer, a spread-spectrum modulator, and a bank of selectable low jitter oscillators to provide the necessary flexibility for advanced designs. The SI51218-A07980-GM offers the lowest power consumption and highest performance in its class, making it an ideal choice for efficient clock/timing applications.
