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). The frequency tuning and control words are loaded into
the AD9859 via a serial I/O port.
The AD9859 is specified to operate over the extended industrial
temperature range of –40°C to +105°C
