AD9952:  400 MSPS 14-Bit DAC 1.8 V CMOS Direct Digital Synthesizer

Product Details

Product Status:Recommended for New Designs

The AD9952 is a direct digital synthesizer (DDS) featuring a 14-bit DAC (digital-to-analog converter) and operating up to 400 MSPS. The AD9952 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 AD9952 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 AD9952 via a serial I/O port. The AD9952 is specified to operate over the extended industrial temperature range of −40°C to +105°C.

Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
This month we conclude our two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
