AD9858 Datasheet 1 Gsps Direct Digital Synthesizer

Manufacturer: Analog Devices

Overview: 1 GSPS Direct Digital Synthesizer AD9858.

General Description

The AD9858 is a direct digital synthesizer (DDS) featuring a 10-bit digital-to-analog converter (DAC) operating up to 1 GSPS.

The AD9858 uses advanced DDS technology coupled with an internal high speed, high performance DAC to form a digitally programmable, plete high frequency synthesizer capable of generating a frequency-agile analog output sine wave at up to 400 MHz.

The AD9858 is designed to provide fast frequency hopping and fine tuning resolution (32-bit frequency tuning word).

Key Features

  • 1 GSPS internal clock speed Up to 2 GHz input clock (selectable divide-by-2) Integrated 10-bit DAC Excellent phase noise and SFDR 32-bit programmable frequency register Simplified 8-bit parallel and SPI serial control interface Automatic frequency sweeping capability 4 frequency profiles 3.3 V power supply Power dissipation: 2 W typical Integrated programmable charge pump and phase frequency detector with fast lock circuit Isolated charge pump supply up to 5 V Integrated 2 GHz mixer.
