Description
AI
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.ApplicationsAgile LO frequency synthesisProgrammable clock generatorsTest and measurement equipmentAcousto-optic device drivers
