Overview
The ADF4153BRUZ-RL is a fractional-N frequency synthesizer produced by Analog Devices Inc. This component is designed to implement local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. It features a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. The synthesizer also includes a Σ-Δ based fractional interpolator, allowing for programmable fractional-N division.
