Product Introduction

Overview

The ADF4158CCPZ, produced by Analog Devices Inc., is a 6.1 GHz fractional-N frequency synthesizer designed with direct modulation and waveform generation capabilities. This device is particularly suited for applications requiring high-frequency resolution and fast lock times. 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 ADF4158 also supports various modulation schemes such as frequency shift keying (FSK) and phase shift keying (PSK), as well as multiple frequency sweep modes generating sawtooth and triangular waveforms.
