AD9859 Datasheet 400 MSPS/ 10-Bit/ 1.8 V CMOS Direct Digital Synthesizer

Manufacturer: Analog Devices

Overview: 400 MSPS, 10-Bit, 1.8 V CMOS Direct Digital Synthesizer AD9859.

General Description

The AD9859 is a direct digital synthesizer (DDS) featuring a 10-bit DAC operating at up to 400 MSPS.

The AD9859 uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a digitally programmable, complete high frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform at up to 200 MHz.

The AD9859 is designed to provide fast frequency hopping and fine tuning resolution (32-bit frequency tuning word).
