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, 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 and tuners. The AD9858 also features a divide-by-2 on the clock input, allowing the external reference 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.

Tools & Simulations

ADIsimDDS (Direct Digital Synthesis)

ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. ADIsimDDS calculates the required FTW, given the reference clock frequency and desired output frequency. This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters.
