www.analog.com GENERAL DESCRIPTION
The AD9858 is a direct digital synthesizer (DDS) featuring a
10-bit DAC operating up to 1GSPS. The AD9858 uses advanced
DDS technology, coupled with an internal high speed, high
performance D/A converter to form a digitally programmable,
complete 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). The
frequency tuning and control words are loaded into the AD9858
via parallel (8-bit) or serial loading formats. The AD9858
contains an integrated charge pump (CP) and phase frequency
detector (PFD) for synthesis applications requiring the
combination of a high speed DDS along with phase-locked loop
(PLL) functions. An analog mixer is also provided on-chip for
applications requiring the combination of a DDS, PLL, and
mixer, such as frequency translation loops, tuners, and so on.
The AD9858 also features a divide-by-2 on the clock input,
allowing the external clock to be as high as 2 GHz.
The AD9858 is specified to operate over the extended industrial
temperature range of –40°C to +85°C.
