ADF4117BRUZ-RL is a low-cost, highly stable clock generator and frequency synthesizers that are ideal for several applications.

This clock generator is recommended for industrial, medical and consumer applications such as Wi-Fi, Bluetooth, and GSM transceivers. It also supports high-performance applications such as cable headend applications and test and measurement.

This generator features a low RMS jitter of 1ps and a wide operating voltage range from 1.8 to 4.5V. Additionally, it supports frequency range of 25MHz to 2.5GHz with step sizes as small as 10kHz.

The working principle and design of the ADF4117BRUZ-RL can be broken down into three main components; the PLL, the VCO, and the Digital Control Logic. The PLL is a type of servo control system, in which an oscillator is actively tracked by feedback from a reference source. The PLL is what allows the oscillator to lock onto a specific frequency, and will continuously adjust the frequency based on the phase and frequency error signals.

The VCO, or voltage-controlled oscillator, is where the actual oscillation frequency is set. It is comprised of a resonator circuit and an amplifier, connected in a loop. The resonator responds to the change in supplied voltage such that the oscillation frequency gets higher when more voltage is supplied. This allows the PLL to control the output frequency by supplying different voltages.

The digital control logic is responsible for responding to the commands sent by the user. This is usually done through a serial interface which allows the user to change settings such as frequency, output channel, etc. It also handles generating the control signals needed by the PLL and the VCO, ensuring they are correctly supplied the required voltages.

The ADF4117BRUZ-RL is well-suited for applications that require high precision in both accuracy and stability. Its low RMS jitter and wide voltage range make it an excellent choice for various applications. It is also a great choice for power-sensitive applications as it is optimized for low power consumption.
