The AD9517-1ABCPZ is a clock/timing device designed as a clock generator, PLL, and frequency synthesizer, offering wide versatility and flexibility in clock and timing applications. It is suitable for a wide range of designs, from servers and test equipment to ASICs and FPGAs. The chip is programmable, allowing it to be configured to the exact requirements of the application. It is available in various packages including a Small Outline Integrated Circuit (SOIC) and a quad flat no-lead (QFN) package.

The AD9517-1ABCPZ utilizes a unique combination of clock synthesis, PLL and programmability to provide comprehensive clock generation, distribution and synchronization capabilities. It includes a number of programmable features, such as input and output dividers, phase-locked loop (PLL) dividers and architecture, polarity control and output edge selection. The chip offers an on-chip voltage-controlled oscillator (VCO), with an operating range of 2.7 GHz to 44 GHz. It also features four phase-locked loops that can provide phase and frequency accuracy. Additionally, the device contains several phase-locked loop sequencers which can be used to provide complete control of the exact frequencies at which the outputs are driven.

The chip boasts a wide range of integrated features that make it an extremely versatile and suitable solution for any timing application. The power supply and the system clock inputs are combined on the chip’s integrated power supply- and system clock-multiplexers; this simplifies the power and system clock distribution requirements of the board, improving board layout and minimizing the number of components required. The chip also includes a programmable watchdog timer, providing an external interrupter if the internal monitoring fails. It also includes a power-down function to shut down all internal circuitry when not in use, which helps maximize the chip’s energy efficiency and minimize power consumption.

The AD9517-1ABCPZ also features an advanced jitter attenuation technology (JAT) to minimize any jitter that may be present at its inputs. The chip also incorporates Digital Fractional-N Synthesis (DFS) for improved accuracy in frequency synthesis and flexible output ratios. The DFS enables a PLL to produce a wide range of output frequencies with very low jitter.

The AD9517-1ABCPZ also offers a wide range of configurable options and features. It supports four outputs with up to 3 GHz frequency; each output can be configured as either a single-ended or differential output. A range of user-programmable attributes, such as input and output dividers, can be configured to meet the specific requirements of the application. The chip also includes a wide range of system interconnects, such as an SPI bus, to facilitate communications with the system microcontroller.

In conclusion, the AD9517-1ABCPZ is an excellent choice for a wide range of clock/timing applications, offering great performance and excellent value for money. The chip offers comprehensive clock generation, distribution and synchronization capabilities, and its programmability, flexibility and configurability make it suitable for a wide variety of applications. Additionally, its advanced jitter attenuation and DFS technologies help ensure the best possible clock performance.
