Working Principles

The ADF4111BRUZ operates based on the principles of phase-locked loop (PLL) frequency synthesis. It uses a reference clock input and a voltage-controlled oscillator (VCO) to generate an output frequency that is locked to the reference input.

The PLL compares the phase and frequency of the reference input with the VCO output and adjusts the VCO control voltage to maintain synchronization. The charge pump, loop filter, and programmable prescaler are used to fine-tune the output frequency and achieve desired performance characteristics.
