Product Summary
The AD9955KS is a direct digital synthesizer (DDS) featuring a 14-bit DAC operating up to 400 MSPS. The AD9955KS 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 AD9951 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 AD9951 via a serial I/O port. The applications of the AD9955KS include Agile LO frequency synthesis, Programmable clock generators, Test and measurement equipment, Acousto-optic device drivers.
