Working Principles

The ADF4153YCPZ utilizes a fractional-N phase-locked loop (PLL) architecture to generate precise output frequencies. It combines a high-resolution delta-sigma modulator, a low-noise digital-to-analog converter (DAC), and a wideband VCO. The PLL compares the divided output frequency with the reference frequency and adjusts the VCO control voltage to minimize the phase difference. This feedback loop ensures accurate frequency synthesis.
