Overview
The ADF4159WCCPZ-RL7 is a high-performance, 13 GHz fractional-N frequency synthesizer produced by Analog Devices Inc. This device is designed for applications requiring fast and precise frequency generation, including modulation and waveform generation capabilities. It features a 25-bit fixed modulus, allowing for subhertz frequency resolution, and includes a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. The synthesizer supports various modulation schemes such as frequency shift keying (FSK) and phase shift keying (PSK), and it can generate sawtooth, triangular, and parabolic waveforms.
