ADF4159WCCPZ-RL7

Overview

The ADF4159WCCPZ-RL7 is a 13 GHz fractional-N frequency synthesizer with direct modulation and waveform generation capabilities. It features a low-noise digital phase frequency detector (PFD) supporting frequencies up to 110 MHz, enabling fast lock times without loop filter modifications. The device utilizes a 25-bit fixed modulus for sub-Hertz frequency resolution. It operates on a 2.7 V to 3.45 V analog supply and a 1.62 V to 1.98 V digital supply. Key specifications include a normalized phase noise floor of −224 dBc/Hz and programmable charge pump currents ranging from 300 µA to 4.8 mA.
