AD9517-1ABCPZ-RL7 is a member of Analog Devices’ precision jitter attenuators and clock synthesizers. It is a monolithic, low-noise, PLL-based device used to minimize jitter and noise in high-frequency clock signals in a range of commercial, medical, communication, and aerospace applications. The AD9517-1ABCPZ-RL7 is well suited for a variety of clock management applications, including Ethernet and wireless communication, medical imaging, and military/aerospace systems.

AD9517-1ABCPZ-RL7 comprises a precision jitter attenuator and clock generator. The jitter attenuator is a low-noise oscillator that can be used as a reference clock source to provide a clean input signal to the PLL. The jitter attenuator is designed to achieve up to 100ps of jitter attenuation for input frequencies up to 1GHz. It contains a phase detector, a low-noise current-mode loop filter, and a voltage-controlled oscillator (VCO). The PLL is a digitally tuned, low-noise frequency synthesizer designed to provide a wide range of output frequencies with low power consumption. The PLL is designed for a dynamic frequency range of1GHz and up to 500MHz using adaptive dynamic frequency scaling. The output of the PLL is actively and dynamically tuned using a sigma-delta control loop, which allows for precise frequency control and low jitter.

AD9517-1ABCPZ-RL7 is used in a wide range of applications, including precise frequency slicing, reference generation, clock distribution, military/aerospace systems, low-noise clock synthesis, Ethernet, and wireless communication. The precision jitter attenuator can be used to eliminate the jitter or noise in high-frequency clock signals, while the PLL can be used to generate precise clock signals tailored to specific needs. Additionally, the wide dynamic frequency range allows for efficient power optimization for a variety of applications.

AD9517-1ABCPZ-RL7 supports full spread spectrum clocking to meet the new jitter reduction standards. The spread spectrum clock generator is a low-noise oscillator with low jitter performance. The spread spectrum clock generator supports up to ±100PPM output frequency variation and can be configured to operate in either constant-amplitude or constant-center spread spectrum clocking mode. With the spread spectrum mode, the clock output is spread over a range up to ±500 PPM, providing a broad spectrum of frequencies to reduce the peak-to-peak jitter. The spread spectrum clock generator can also be used as a reference clock, providing a low-noise and low-jitter input clock to the PLL.

AD9517-1ABCPZ-RL7 is an excellent choice for low-noise and low-jitter clock synthesis and is suitable for a variety of applications in the industrial, communication, medical, and military/aerospace fields. With its high-performance jitter attenuator and wide dynamic frequency range, the AD9517-1ABCPZ-RL7 can reduce frequency errors and noise, reduce overall power consumption, and improve system performance.
