The ADF4117BRUZ is a clock and timing device and is categorized under Clock/Timing – Clock Generators, PLLs and Frequency Synthesizers. This family of devices are designed to provide an accurate programmable frequency synthesizer with automatic locking to a reference frequency. The ADF4117BRUZ is also used as a clock generator; it is capable of providing a wide range of programmable clock frequencies from a single external reference.

By combining both PLL and Voltage-Controlled Oscillator (VCO) architectures, the ADF4117BRUZ is able to provide a wide range of clock frequencies. The VCO allows for synthesis of frequencies up to 375 MHz and the PLL is able to generate a very low jitter clock (500 fs maximum) which allows for very reliable clocking in high-speed applications.

The ADF4117BRUZ family of devices are most commonly used in applications where efficient clock generation and frequency outputs are required. These devices are commonly used in high-speed telecommunications, where they are used to create data rates up to 6.144 Gbps. The devices are also used in Industrial Automation and Control, where they are used in motion control systems and in high-frequency RFID applications. Other applications include video processing, automotive engine control and digital audio, among others.

The ADF4117BRUZ device functions by using a divide-by-N prescaler, a Charge Pump, a Programmable Reference Divider, and a phase detector. The programmable dividers can be configured to divide the reference clock by any integer from 1 to 32, providing a very wide range of frequency generation in the output. The Charge Pump is used to supply current to the VCO and to tune the VCO frequency more precisely. The phase detector compares the phase of the output from the programmable dividers with that of the reference input to ensure that the output of the PLL is always on frequency. This provides an efficient and reliable way to generate a wide range of programmable clock frequencies.

The ADF4117BRUZ is a very efficient and reliable way to generate a wide range of programmable clock frequencies. The device is capable of providing very low jitter and is suitable for a range of high-speed applications, including telecommunications, Industrial Automation and Control, video processing, automotive engine control and digital audio. It is also capable of providing a very wide range of frequencies, up to 6.144 Gbps, with a fast lock time and an optimal level of noise performance. The combination of PLL and VCO architectures with two programmable dividers and a charge pump, provides an efficient and reliable choice for clock generation.
